Skills and Specialties

A NOTE: To apply a modifier to a skill roll, simply scroll your mousewheel up or down over the "Modifier" box next to your dice tray. If rolling by double-clicking your skill chance, the modifier will automatically be added or subtracted to your listed skill rating. This Is Pretty Handy.
==Occupation and Skills==
To begin with, choose an occupation. Anything you think would be interesting to play is valid, but you should confirm this with your keeper. The occupations are only limited by your imagination. Once you have select the occupation, you should look at the list of skills on you character sheet.
===Occupational Skills===
Choose 8 skills which are appropriate for your character's chosen occupation. These are your "Occupation Skills." You now have to assign percentile points to the skills on the character sheet. Before you do so, please note that no skill can start play with a rating higher than 75.
You multiply your EDU score by 20 to get the number of points to spread amongst your Occupation Skills. Add any number of these points to the eight skills you chose.
Each skill on the character sheet also has a number in parenthesis next to it. This is the "Base Chance" that every investigator has with that skill. Any points you add to a skill stack with its Base Chance.
For example, if you add 15 points to the "Conceal" skill (Base Chance of 15) you would have "Conceal: 30".
===Hobby Skills===
After selecting the Occupation Skills, select your Hobby Skills. These are skills that your character has acquired over the course of his life. To determine how many points you have to spend on them, multiply your INT score by 10. Divide those points amongst any skills on the sheet you would like. Note that you may wish to save a few skill points to buy combat skills.
===Sample Occupations===
In the section below you have sample occupations from the Call of Cthulhu source-book. Do not take these as strict guides for this character occupation, merely as examples of how an occupation can help define a character.
====Antiquarian ====
=====Description=====
Revels in the timeless excellence of design and execution, and in the power of ancient lore, the most Lovecraft-like occupation. The antiquarian rarely deals in what he loves. More often, an independent income allows him to sharpen and define his pleasure in things old and obscure. He ahs an appreciative eye and a swift mind, and frequently finds mordant or contemptuous humor in the foolishness of the ignorant, the pompous, and the greedy – or are those perceptions clues to his own mental instability?
=====Skills =====
: Art, Bargain, Craft, History, Library Use, Other Language, Spot Hidden, and any one other skill as a personal or era specialty.
====Artist====
=====Description =====
: Self-absorbed with his own visions, but is blessed with a talent that lets him express himself. Often he also has a crafty entrepreneurial streak, and is usually a painter or a sculptor. Talented or not, the artist’s ego must be hardy and strong to surmount initial obstacles and keep him working if success arrives.
=====Skills =====
: Art, Craft, Fast Talk, History, Photography, Psychology, Spot Hidden, any other one skill as a personal or era specialty.
====Author ====
=====Description =====
: Distinct from the journalist, the author uses words to define and explore the conditions of human life, and especially the range of human emotions. It is said that an author does not so much write as rewrite; his labors are solitary and his rewards solipsistic: only a relative handful make much money. The work habits of authors vary widely. Typically an author withdraws during periods of intense creation. The author who is constantly expansive and sociable is written-out, or perhaps had no talent to start with.
=====Skills =====
: History, Library Use, Occult, Other Language, Own Language, Persuade, Psychology, and any one other skill as a personal or era specialty.
====Dilettante ====
=====Description=====
: The dilettante has so much money that specialists are needed to take care of it. He or she is well educated, though not systematically educated or necessarily accomplished in anything. Money frees the dilettante to be eccentric and outspoken. He or she has had plenty of time to learn how to be charming and sophisticated; what else has been done with that time betrays the dilettante’s true character. Lacking financial compulsion, his or her family relations are sometimes very odd.
=====Skills =====
: Art, Craft, Credit Rating, Other Language, Ride, Shotgun, any two other skills as personal or era specialties.
====Doctor of Medicine ====
=====Description =====
: Perhaps a general practitioner, a surgeon or other specialist, a psychiatrist, or an independent medical researcher. Apart from personal goals, three aims – helping patients, gaining money and prestige, and promoting a more rational and wiser society – are common to the occupation. Doctors tend to be self-sufficient sorts for whom families become adjuncts to respectability.
=====Skills=====
: Biology, Credit Rating, First Aid, Latin, Medicine, Pharmacy, Psychoanalysis, Psychology, any one other skill as a personal or era specialty.
====Drifter ====
=====Description=====
: As opposed to someone who is poverty-stricken, the drifter’s wandering life is chosen, perhaps compensating for social, philosophical, sexual, or economic lacks. The drifter takes jobs, sometimes for months, but he is disposed to solve problems with the answer of mobility and isolation, not comfort or intimacy. The life of the road might seem especially American, but the same sort of life is chosen wherever travel itself is not systematically dangerous.
=====Skills =====
: Bargain, Fast Talk, Hide, Listen, Natural History, Psychology, Sneak, and one other skill as a personal or era specialty.
====Entertainer ====
=====Description =====
: This occupation might include dancer, singer, juggler, athlete, musician, or anyone else who earns a living in front of an audience. These people love to be seen, love to show what they do best, and love the consequent applause. These proclivities can be observed in children as young as age three or four, but the talent that reaps success may lie fallow for years. Show-business families make excellent incubators.
=====Skills=====
: Art, Credit Rating, Disguise, Dodge, Fast Talk, Listen, Psychology, any one other skill as a personal or era specialty.
====Journalist ====
=====Description=====
: Uses words to report and comment upon topics and incidents of the day, writing as many words in a day as an author may in a week. Journalists work for newspapers, magazines, and radio and television news services. The best report, but keep themselves independent of the corruption and self-serving they witness. That reality overwhelms the worst, who eventually forfeit any sensibility except for the power of their words.
=====Skills=====
: Fast Talk, History, Library Use, Own Language, Persuade, Photography, Psychology, any one other skill as a personal or era specialty.
====Missionary====
=====Description=====
: You have accepted the call to spread the word of God. May be independent of all except his or her vision, or may be backed by some organization to do just that – and in that case has demonstrated some ability to perform such duties. The clear-sighted missionary is able to focus on the humanity of the converts and does not confuse alien customs with human souls, so that questions of dress, behavior, or diet do not become paramount. Where morality leaves off and religion begins is by no means clear. This occupation requires settled emotions and a sense of humor. The successful missionary remains personally humble and exalts God. Christian and Islamic proselytizers are encountered worldwide, as well as Buddhist and Hindu teachers.
=====Skills=====
: Art, Bargain, Craft, First Aid, Mechanical Repair, Medicine, Natural History, Persuade, any one other skill as a personal or era speciality.
====Parapsychologist====
=====Description=====
:Prestigious universities grant no degrees for parapsychology. Standards in the field are based entirely upon personal reputation, and so the most acceptable representatives tend to hold degrees in related areas – physics, psychology, or medicine. Who chooses this study is unusually sympathetic to the notion of invisible mystical powers, and in validating that belief to the satisfaction of physical scientists. This would represent an unusual cohabitation of faith and doubt – the parapsychologist may have difficulty separating the conflicting desires. A person uninterested in observation, experiment, and proof is not a scientist, though he or she may be an occultist.
=====Skills=====
: Anthropology, History, Library Use, Occult, Other Language, Photography, Psychology, any one other skill as a personal or era specialty.
====Police Detective====
=====Description=====
:Though present day detectives may attend police science classes, take a degree, and undergo special training and endless civil service exams, police detectives of every era are grounded in their experiences as junior officers and ordinary patrolmen. Police routine and discipline becomes vital to self-identification as well as an ongoing source of frustration as the detective is tempted by extralegal shortcuts to successful arrests. The police detective may be a manager who coordinates staff in some important investigation, but rarely has the luxury of concentrating on a single case. In the United States, his responsibilities at any one time may number in the dozens or hundreds of open cases. The detective’s crucial function is to marshal enough evidence to allow an arrest, in turn leading to a successful criminal prosecution. Detectives everywhere sort truth from lies by evidence and reconstruction. The offices of detective and prosecutor are everywhere separate, so that the evidence may be weighed independently before trial.
=====Skills=====
: Bargain, Fast Talk, Law, Listen, Persuade, Psychology, Spot Hidden, any one other skill as a personal or era specialty.
====Private Eye ====
=====Description=====
:In most places the private investigator is licensed by the police and must be privately bonded as well, guarantees of minimal honesty. Proven malfeasance costs him his license and puts him out of business. The private eye usually acts in non-police situations: he gathers information and evidence for private clients in impending civil cases, tracks down fleeing spouses or business partners, or acts as an agent for private defense attorneys in criminal cases. In detective classics, the private eye is hired to handle some ordinary civil or private matter (such as a cheating spouse), and then is drawn into the investigation of a murder or series of murders as the case unfolds. Like any professional, the private eye separates his personal feelings from the job at hand, and cheerfully works for the guilty and innocent alike, as long as his fee is paid. The private investigator is usually shown to have been a member of a police force in the past, using those connections to his advantage in the present. Usually he is not prosperous and never has known much money, but his private code and keen awareness purify his manners. Depending on state or local law, police experience may not be necessary.
=====Skills=====
: Bargain, Fast Talk, Law, Library Use, Locksmith, Photography, Psychology, and any one other skill as a personal or era specialty.
====Professor ====
=====Description=====
:For the most part the occupation indicates a Ph.D. That rank can earn tenure at universities around the world. He is qualified to teach and to perform competent research, and has discernible academic reputation in his area of expertise. He may be an absolute idiot in other fields, of course, and such contradictory investigators are fun to play. Unless they are of independent means, and have taken leave of their universities, professor-investigators tend to be tethered close to home by their ongoing responsibilities to school and students. Indiana Jones was lucky to have a department head who would allow extended absences – your investigator may not have such an understanding boss.
=====Skills=====
: Bargain, Credit Rating, Library Use, Other Language, Persuade, Psychology, and any two of the following as a personal specialty: Anthropology, Archaeology, Astronomy, Biology, Chemistry, Electronics, Geology, History, Law, Medicine, Natural History, or Physics.
==Skill Specialties==
Whenever you have a declared specialty - and for combat skills, this specialty need be very specific, considering the particular specificity of combat skills - you add +15% to all rolls involving that specialty. This is added before any other modifiers to skill chance, including halving or doubling; it represents a significantly higher base chance with that skill. 
As with World of Darkness, specialties can be taken up to 3 times. If you really want to be an ace with a fencing foil or know everything there is to know about operating a scanning electron microscope, go right ahead. Yeah I have +45% to all rolls involving Flemish painters of the Renaissance. Note a specialty, despite its specificity, is not tied to a single skill as is the case in the WoD rules - having a specialty in, say, Flemish painters of the Renaissance would convey that specialty's bonus to all skills wherein that specialty is relevant.
==Skills and Starting Ratings==
Combat Skills, starting ratings, and descriptions are listed on the Combat Conversion Rules page.
*Accounting (10%) – Grants understanding of accountancy procedures, and reveals the financial functioning of a business or person. Inspecting the books, one might detect cheated employees, siphoned-off funds, payment of bribes or blackmail, and whether or not the financial condition is better or worse than claimed. Looking through old accounts, one could see how money was gained or lost in the past (grain, slave-trading, whiskey-running, etc.) and to whom and for what payment was made.
*Anthropology (01%) – Enables the user to identify and understand an individual’s way of life from his behavior. If the skill-user observes another culture from within for a time, or works from accurate records concerning an extinct culture, he or she may make simple predictions about that culture’s ways and morals, even though the evidence may be incomplete. Studying the culture for a month or more, the anthropologist begins to understand how the culture functions and, in combination with Psychology, may predict the actions and beliefs of representatives. Essentially useful only with existing human cultures.
*Archaeology (01%) – Allows dating and identification of artifacts from past cultures and the detecting of fakes. Having thoroughly inspected a site, the user might deduce the purposes and way of life of those who left the remains. Anthropology might aid in this. Archaeology may also help identify written forms of extinct human languages.
*Art (05%) – Specify song, some musical instrument, painting, cooking, etc. – any non-literary art which a creative person might seriously pursue through life. With a success, the performance or creation is pleasing and the audience is satisfied. Failure indicates that the artist was off-key or inexpressive. Lovecraft’s artists invoke the traditional muses, but the keeper might allow wider definitions of “art”. The points where Art ends and Craft begins vary with each keeper. The investigator sheet contains blank spaces for different versions of this skill. The player should note the style or medium – opera singer, oil painter, etc.
*Astronomy (01%) – The user knows or knows how to find out which stars and planets are overhead at a particular day or hour of day or night, when eclipses and meteor showers occur, and the names of important stars, and something of current perceptions about life on other worlds, the existence or the formation of galaxies, and so on. An academic might be able to calculate orbits, or discuss stellar life cycles.
*Bargain (05%) – The skill of obtaining something for an agreeable price. The bargainer must state the price at which he or she wishes to purchase the item and, for each 2% difference between the price and the asking price, he or she must subtract 1 percentile from his Bargain skill. The seller will not take a loss, no matter how good the bargaining. The keeper usually determines the bottom-line secretly. Example: Harvey Walters purchases a shotgun in Germany, to take with him while he investigates the disappearance of his manservant, Kurt, in the old ruins nearby. The elderly shopkeeper asks $100 American for the weapon, and Harvey is on a limited budget. Harvey offers the shopkeeper $70, and his player makes a D100 roll. Harvey has Bargain 20%, but he wants the gun for 30% less than normal, so his chance of success is reduced by 15 percentiles to only 5%. The player rolls 22 – a failure. Harvey then offers 80%, increasing his chances to 10%. The player rolls 02, a success
: By implication, use this skill in any negotiation which features an exchange value. Combination rolls with Credit Rating, Fast Talk, or Persuade might help in bargaining.A simple bargain may be struck in a few minutes. A complex contract might take weeks, and Bargain might then work in combination with Law.
*Biology (01%) – The science of life, including botany, cytology, ecology, genetics, histology, microbiology, physiology, zoology, and so on. The investigator’s understanding reflects the era of play. With this skill one might develop a vaccine against some hideous Mythos bacterium, or isolate the hallucinogenic properties of some jungle plant.
*Chemistry (01%) – A study of the composition of substances, the effects of temperature, energy, and pressure upon them, and how they affect one another. With chemistry, one might create or extract complex chemical compounds, including simple explosives, poisons, gases, and acids, requiring at least a day or so with the proper equipment and chemicals. The user could also analyze an unknown substance, given proper equipment and reagents.
*Climb (40%) – A climb roll must be attempted every 10 to 30 vertical feet, depending on the difficulty of the climb as the keeper perceives it. Conditions such as firmness of surface, wind, visibility, rain, etc., may be factors.
*Conceal (01%) – Allows the visual covering up, secreting, or masking of an object or objects, perhaps with debris, cloth, or other intervening or illusion-promoting materials, perhaps by making a secret panel or false compartment, or perhaps by repainting or otherwise changing an item’s characteristics to escape detection. With it, a person might be secreted from sight, but could not be disguised to evade even a cursory inspection. Larger objects of any sort should be increasingly harder to conceal. Things larger than elephants should not be concealed by one person, though they might be a group.Compare with the Hide skill.
*Craft (05%) – A craft is a specialized skill for making and repairing practical things or for creating pleasing effects. It requires manual dexterity or artful application. As an occupation, a craft typically provides more income than laboring, but not as much as a profession. A multitude of crafts exist, from house painter to lion-tamer to safecracker. Particularize a craft on craft on the investigator sheet, in the same general fashion as for Art: for instance, Craft (Cobbler), Craft (Barber), or Craft (Blow/Vacuum Tube).Making or repairing something typically requires equipment and time, to be determined by the keeper if necessary. With a very low result, a craftsman might make exceptionally fine item. With a failing roll, the item might break on its first use, or fail to fit into some larger whole. A successful Craft roll might provide information about an item, such as where or when it might have been made, reveal some point of history or technique concerning it, or who might have made it.
*Credit Rating (15%) – Narrowly, how prosperous and confident the investigator seems to be. This is the investigator’s chance to panhandle or get a loan from a bank or business, and it is also the chance for the investigator to pass a bad check or to bluff past a demand for credentials. In small towns, or in narrow societies such as Edwardian England, everyone knows everyone, and Credit Rating amounts to an index of personal reputation as well as monetary worth. Thus, Credit Rating might ebb and flow because of scandal or personal behavior, while the loss of accumulation of money effected minor change or no change. As appropriate, the keeper may cause a character to make clear such distinctions.
*Disguise (01%) – The user changes posture, costume, and/or voice in order to seem another person or another sort of person. Theatrical makeup may help. Dim lighting definitely helps. Increase the chance for detection if the disguise involves significant differences in sex, age, size, or language. To look like a specific person, as opposed to a particular kind of person, halve the Disguise skill percentage – this sort of illusion is best left maintained by distance.A successful Spot Hidden or a Psychology roll might lead an observer to suspect someone in disguise. A successful Fast Talk roll by the player of the disguised character lowers the success for either of those skills by 10 percentiles.Though explaining die results is the province of the keeper, a low and successful D100 result might give the disguised character some ability to issue convincing orders or to pass inspection by intimates. A failed Disguise roll causes onlookers to notice uncharacteristic behavior or expression. A very high failure, from 90 to 00, declares in effect, “This person is suspicious! Investigate immediately!”
*Drive Automobile (20%) – Anyone with this skill can drive a car or light truck, make ordinary maneuvers, and cope with ordinary vehicle problems. If the investigator wants to lose a pursuer or trail someone, both participants might attempt Driving rolls until one fails and the other succeeds. Dangerous maneuvers always call for Drive rolls.
*Electrical Repair (10%) – Enables the investigator to repair or reconfigure electrical equipment such as auto ignitions, electric motors, fuse boxes, and burglar alarms. To fix an electrical device may require special parts or tools. Jobs in the 1920s may call for this skill and for Mechanical Repair in combination.
*Fast Talk (05%) – Causes a target to agree with the user for a short time. Without reflecting, the target signs the paper, allows the trespass, lends the automobile, or whatever else within reason is asked. Given a little more time to think and the benefit of a successful Idea roll, the target comes to his or her senses, and the Fast Talk loses effect. In a few game minutes, Fast Talk may pass off suspect goods as valuable, false facts as reliable, and fine items as not worth bothering about. In contrast, Persuade and Bargain may take hours or days to conclude. Fast Talk is quick to take effect, but it can be used at most on a handful of people. Fast Talk will not work on targets whose minds are made up; use Persuade instead.
*First Aid (30%) – The percentage change of awakening an unconscious or stunned comrade, setting a broken limb, treating burn damage, resuscitating a drowning victim, etc. First Aid has no effect on diseases or subtle physical ailments, nor on poisonings unless the keeper allows the roll. Treated with First Aid, an investigator’s healing rate stays at 1D3 points per week. (Moved to a hospital and successfully treated with Medicine, that rate rises to 2D3 per week.) Failure in applying First Aid requires that the user wait some reasonable amount of time to try again (something new, presumably, since what was done didn’t work), but another practitioner could make an attempt in the next round.
-A success with this skill allows the user immediately to heal 1D3 points of a single attack or injury. Thus an investigator suffering multiple gunshot wounds might receive First Aid for each, as long as they were not incurred in the same combat round.
-In the same or the succeeding combat round, an investigator who has just died may be returned to life if the emergency treatment raises hit points to at least +1.
-A success with First Aid immediately awakens any victim of a knocked-out attack and, if the keeper wishes, anyone unconscious for other reasons.Once a character has had First Aid successfully applied to an injury, further applications either of First Aid or of Medicine have no effect on that injury. A new injury would be treated independently. An application of the skill takes a combat round, or as the keeper determines. See also Medicine.
*Geology (01%) – Enables an investigator to tell the approximate age of rock strata, recognize fossil types, distinguish minerals and crystals, locate promising sites for drilling and mining, evaluate soils, and anticipate volcanism, seismic events, avalanches, and other such phenomena. Sherlock Holmes was expert in London-area soils, and could trace a man’s movements by studying the dirt on his boots.
*Hide (10%) – As opposed to Conceal, Hide concerns the individual user’s ability to escape detection in an unprepared position. Use this skill only in a pursuit situation, or when under surveillance or patrol. It lets the user choose objects, bushes, deep shadows, etc., in which to lurk for a while. Some sort of cover must be present. In an area being watched, the user can move while hiding. Figure the chance for successful movement by halving the Hide skill amount.
*History (20%) – Enables an investigator to remember the significance of a country, city, region, or person, as pertinent. Lessen the chance if the facts are obscure. A successful History roll might be used to help identify tools, techniques, or ideas familiar to ancestors, but little known today.
*Jump (25%) – With a success, the investigator can leap up vertically and grab to his or her height, safely leap down vertically to his or her height, jump horizontally from a standing start across a gap for a distance equal to the jumper’s own height, or run and then jump horizontally to a distance of twice the jumper’s own height. If falling from a height, a successful Jump prepares for the fall, subtracting 1D6 from the loss to injury.
*Law(05%) – Represents the chance of knowing pertinent law, precedent, legal maneuver, or court procedure. The practice of law as a profession can lead to great rewards and political office, but it requires intense application over many years. A high Credit Rating is crucial to it. No other profession is so easily sullied by the bizarre behavior common to investigators. In the United States, one’s practice of law must be sanctioned by the State Bar of a particular commonwealth or state. In another country, halve the chance for success with this skill, unless the character has spent 30-INT months studying that nation’s law.
*Library Use (25%) – In many ways this is the most important skill in the game. Library Use enables an investigator to find a given book, newspaper, or reference in a library or collection of documents, assuming that the item is there. Each use of this skill marks four hours of continuous search. An investigator rarely gets more than two tries per day.This skill can Locate a locked case of rare-book special collection, but Fast Talk, Persuade, Bargain, Credit Rating, a bribe, or special credentials might be needed to get at the books.
*Listen (25%) – Measures the ability of an investigator to interpret and understand sound, including overheard conversations, mutters behind a closed door, and whispered words in a café. The keeper may use it to determine the course of an impending encounter: was your investigator awakened by that crackling twig? By extension, a high Listen can indicate general awareness in a character.
*Locksmith (01%) – The user may repair locks, make keys, or open locks with the aid of skeleton keys, picks, and other tools. Especially difficult locks may lower the chance for success. A locksmith can open car doors, hot-wire autos, jimmy library windows, figure out Chinese puzzle boxes, and penetrate ordinary commercial alarm systems. Sophisticated safes, vaults, and other serious defensive systems are beyond your skill. Keepers might combine Locksmith with DEX or POW rolls to cover a variety of surreptitious situations.
*Mechanical Repair (20%) – This allows the investigator to repair a broken machine, or to create a new one. Basic carpentry and plumbing projects can be performed. Special tools or parts may be required. This skill can open common household locks, but nothing more advanced. See the Locksmith skill. Mechanical Repair is a companion skill to Electrical Repair, and both may be necessary to fix complex devices such as an auto or an aircraft.
*Medicine (05%) – The user diagnoses and treats accidents, injuries, diseases, poisonings, etc., and makes public health recommendations. If an era has no good treatment for a malady, the effort is limited, uncertain, or inconclusive. Failure in application requires that the user wait some amount of time to try again, but another practitioner could make his or her attempt in the next round.-In an emergency, the successful user of Medicine can immediately restore 1D3 hit points, once per wound or injury.-In the same or the succeeding combat round, an investigator who has just died may be returned to life if hit points rise to at least +1.-An investigator successfully treated with Medicine heals at 2D3 hit points per game week, including the first week.-Including any emergency treatment, the total recovery for the first week of Medicine’s application could be 3D3 hit points.-A success with Medicine immediately awakens any victim of a knock-out attack and anyone unconscious for other reasons.-The keeper may rule that a medical condition is not treatable. See also First Aid.
*Natural History (10%) – Originally the study of plant and animal life in its environment. By the nineteenth century this study had long separated into many academic disciplines. As a game skill it represents the traditional knowledge and personal observation of farmers, fishermen, inspired amateurs, and hobbyists. It identifies species, habits, and habitats in a general way and is able to guess at what may be important to a particular species. Natural History information may or may not be accurate – this is the region of appreciation, judgment, tradition, and enthusiasm. Use Natural History to judge horseflesh at a country fair, or to decide whether a butterfly collection is excellent or just excellently framed.
*Navigate (10%) – Allows the user to find his or her way in storms or clear weather, in day at night. Those of higher skill are familiar with the astronomical tables, charts, instruments, and satellite location gear as they exist in the era of play. One could also use this skill to measure and map an area, whether an island of many square miles or the interior of a single room.
*Occult (05%) – The user recognizes occult paraphernalia, words, and concepts, and identifies grimoires of magic and occult codes when he sees them. The occultist is familiar with the families of secret knowledge passed down from Egypt and Sumer, from the Medieval and Renaissance West, and perhaps from Asia and Africa as well.Comprehending certain books may provide percentiles of Occult.
*Operate Heavy Machine (01%) – Required to drive and operate a tank, backhoe, steam shovel, or other large-scale construction machine. Once the skill is sufficiently known, no skill roll is needed except for difficult and dangerous tasks, or bad or dangerous conditions. For very difficult sorts of machines, the keeper may decide to lower an investigator’s nominal skill if the problems encountered are mostly unfamiliar ones: someone used to running a bulldozer, for instance, will not be quickly competent with the steam turbines of a ship’s engine room.
*Other Language (01%) – Specify the language. An individual can know any number of languages. The skill represents the user’s chance to understand, speak, read, and write in a language other than his or her own. Ancient or unknown languages comparable to Aklo should not be chosen, but ordinary earthly languages may be. Occasionally the keeper may determine that a number of separate complex points exist in a document or speech, and call for several such language rolls, one for each point. Similarly, the keeper may momentarily reduce the user’s skill in a language if archaic speech or writing in that language is encountered. A single successful Other Language roll normally comprehends an entire book.If an investigator has several points in a particular Other Language, he or she grasps the gist of normal conversation. A character needs EDU x 5 or better points in a second language to pass for a native speaker. Blank spaces exist for other languages on the investigator sheet.
*Own Language (EDU x 05%) – Specify the language. In infancy and early childhood, most humans use a single language. For most people in the United States, the tongue is some dialect of English. The tongue chosen by the player for the investigator’s Own Language automatically starts at EDU x5: thereafter the investigator understands, speaks, reads, and writes at that percentage or higher. Normally no skill roll is necessary to use Own Language. If a document is extremely difficult to read, or in an archaic dialect, the keeper may reduce the user’s skill chance in that situation.Authors typically have high Own Language skills.
*Persuade (15%) – Use Persuade to convince a target about a particular idea, concept, or belief. (Like Fast Talk, Persuade may be employed without reference to truth.) Unlike Fast Talk, Persuade’s effect lingers indefinitely and insidiously, for years perhaps, until events or another Persuade turn the target’s mind in another direction. The successful application of Persuade might take an hour to several days, depending on what’s being attempted.
*Pharmacy (01%) – The user recognizes, compounds, and perhaps dispenses a wide variety of drugs and potions, natural and man-made, and understands side effects and contra-indications. He or she has a good practical knowledge of poisons and antidotes, and can use Pharmacy as a first-aid skill in cases of poisoning. The skill grants no ability to diagnose diseases nor the right to prescribe medicines.
*Photography (10%) – Covers both still and motion photography. This skill allows one to take clear pictures, develop them properly, and perhaps enhance half-hidden detail. Failures are blurred or do not show what was desired.
*Physics (01%) – Grants theoretical understanding of pressure, materials, motion, magnetism, electricity, optics, radioactivity, and related phenomena, and some ability to construct experimental devices and test ideas. The degree of knowledge depends on the era of use. Practical devices such as automobiles are not the province of physicists, but experimental devices may be, perhaps in conjunction with Electronics or Mechanical Repair.
*Pilot (01%) – The air/water equivalent of Drive Automobile, this is the maneuver skill for flying or floating craft. An investigator might have several versions of this skill in the spaces on the investigator sheet. Each starts at 01%.-Bad weather, bad visibility, and damage apply to air and water craft.-A skill user of less than 15% knows just enough to get into trouble. He or she can sail or fly on a calm day with good visibility, but needs Luck rolls for take-offs and landings, dockings, changing sails, judging wind and current, etc. Keepers must require Pilot rolls for storms, navigation by instrument, low visibility, and other difficult situations.
: Pilot Aircraft:
The understands and is increasingly competent with a general class of aircraft named below. Upon any landing, even under the best conditions, a Pilot roll must be made. If conditions are good, double the chance of success. If conditions are bad, the pilot lands at his or her normal chance. A failure may represent damage to the craft, which must be repaired before next takeoff. Pilot and passengers may walk away or need Luck rolls to avoid serious injury. A result of 00 is a memorable disaster. 
-Each class of Aircraft counts as a different skill, and should be listed independently: Pilot Balloon, Pilot Dirigible, Pilot Civil Prop.
: Pilot Boat:
The character understands the behavior of small motor and sailing craft in wind, storms, and tides, and can read wave and wind action to suggest hidden obstacles and approaching storms. In a wind, novice sailors will find docking a rowboat difficult.
*Psychoanalysis (01%) – Enables the user to staunch a temporary and indefinite insanity for a day or so. If the condition persists beyond that period, the unfortunate person relapses, and only time heals the insanity. This emergency treatment takes up to an hour to perform, and can be applied just once per person per incident of insanity, no matter how many analysts are available.-Treatment by a psychotherapist can add Sanity points during indefinite insanity.-Psychoanalysis cannot increase a person’s Sanity points beyond POWx5, nor above 99-Cthulhu Mythos.The skill refers to the range of emotional therapies, not just to Freudian procedures. Sometimes it was looked on as a fraudulent study during the 1920s. The common term then for an analyst or scholar of emotional disorders was alienist.
*Psychology (05%) – A skill common to all humans, it allows the user to study an individual and form an idea of his or her motives and character. In general, the keeper will make the rolls for this skill and keep the results secret, announcing only the information, true or false, that the user gained by employing it. Players should not expect that this skill penetrates skillful deceit unless the person’s confidence somehow has been shaken.
*Ride (05%) – Intended to apply to saddle horses, donkeys, or mules. A camel might be ridden successfully at a lowered percentage chance. The skill grants knowledge of basic care of the riding animal, riding gear, and how to handle the steed at the gallop or on difficult terrain.Should a steed unexpectedly rear or stumble, the rider’s chance of remaining mounted equals his or her Ride. If an investigator falls from a mount, either because the animal has collapsed, fallen, or died, or because a Ride roll failed, he or she loses 1D6 hit points in the accident. A successful Jump roll saves 1D6 hit points. Wielding a weapon effectively while riding takes both a weapon skill and a Ride skill in excess of 50%. The keeper might apply modifiers to reflect a particular situation.
*Sneak (10%) – The art of moving quietly, without alerting those who might hear. Used in combination with Hide, the investigator makes a single D100 roll, the result of whichis matched against the investigator’s percentages in both skills. Use this combination when silent movement is necessary. See also Hide.
*Spot Hidden (25%) – This skill allows the user to spot a secret door or compartment, notice a hidden intruder, find an inconspicuous clue, recognize a repainted automobile, become aware of ambushers, notice a bulging pocket, or anything similar. This is an important skill in the game.
*Swim (25%) – The ability to float and to move through water or other liquid. Only roll Swim in times of crisis or danger when the keeper thinks it appropriate. A failing Swim roll starts the drowning procedure. Someone drowning may receive a Swim roll attempt each round – with a success, he or she reaches the surface and breathes. With a second success, he or she can begin to move through the water. If the second Swim roll fails, drowning begins again.
*Track (10%) – With Track, an investigator can follow a person, vehicle, or animal over soft earth and leaves. Subtract 10% from the chance for success for each day that has passed since the tracks were made. Rain may made tracking impossible. A being cannot be tracked across water, over concrete, or at night except in unusual circumstances.
