Engineer

= Engineer =
Engineers are vital members of the Lands of Spira. They’re responsible for building and maintaining weapons, vehicles, airships, Magitek, and more with the help of their Automatons. Although many Engineers confine themselves to workshops, garages, and shipyards, many are drawn to a life of adventure and prefer to work “in the field.” Some of the best and brightest Engineers ply their trade aboard airships, on distant lands, and on the battlefield. Every organization and nation that depends on technology relies on their knowledge. Engineers use their knowledge of how things are put together to more effectively take things apart and are often called in to bypass security measures or whip up special weapons for field troops in dangerous situations.
Role: Engineers travel to pick up new and interesting skills and raw materials for their inventions. Unused to either huge or delicate machines with hissing steam and arcing electricity, common people find engineers disconcerting at the least, and often frightening. Their ability to create useful devices make them well-loved by adventuring parties. A group with an engineer seldom lacks the equipment they require.

== Class Features ==
All of the following are class features of the engineer.
=== Weapon and Armor Proficiency ===
Engineers are proficient with all simple weapons, plus any type of non-exotic crossbows, and simple firearms. Engineers are proficient with light armor, but not with any type of shields.
=== Limit Breaks (Su) ===
At 1st level, the engineer receives the Limit Breaks (Auto-Repair and Overdrive).
Auto-Repair (Su): This Limit Break grants the engineer an aura that extends out to 30 feet around him. Any damaged items or machinery chosen by the engineer within the area of effect start repairing themselves at 4 hit points + an additional 4 hit points per four engineer levels after 1st for a duration of 1 round + 1 round per four engineer levels after 1st. This limit break requires only a swift action.
Overdrive (Su): This Limit Break increases the overall combat effectiveness of the engineer’s automaton. For the duration of 1 round + 1 round per four engineer levels after 1st, the automaton gains a 2/- DR and +2 enhancement bonus to Strength and Dexterity. These bonuses increase by said amount per four engineer levels after 1st. This limit break requires only a swift action.
=== Crafter (Ex) ===
Few can match the engineer’s artifice when creating objects. At 1st level, an engineer gains a bonus equal to half his engineer level (minimum 1) to all Craft skill checks.
=== Repair (Su) ===
An engineer can fix broken items or his automaton with a mere touch. Starting at 1st level, as a standard action that provokes attacks of opportunity, the engineer repairs 1d6 points of damage plus 1d6 points of damage for every other engineer level beyond first (2d6 at 3rd, 3d6 at 5th, and so on). In addition, one use of Repair restores an item affected by the broken condition. The engineer can repair a number of times per day equal to 3 + his Intelligence modifier.
=== Technologist ===
At 1st level, engineers receive the Technologist feat for free.
=== Automaton (Ex) ===
Many engineers create automatons capable of performing a host of duties. Whether or not the servitor is created from intricate clockwork, or steam driven pistons, they share the same capabilities. Unless granted a Master Upgrade, all automatons are unintelligent constructs that follow the engineer’s instructions unfailingly. At 5th and every five levels thereafter, the engineer upgrades an Automaton they currently possess in order to represent his growing skill and power. Upgrades must be performed in order and the engineer must meet the level requirements for the upgrade.
The capabilities granted by previous upgrades remain and stack with any improvements granted by the new upgrade. When installing a new upgrade, the engineer may reconfigure old design decisions, such as damage types, made at previous upgrades unless otherwise noted. If an Automaton is destroyed, the engineer must rebuild from scratch, costing him 100 gil per engineer level in material components, plus 200 gil per upgrade, to rebuild his Automaton. Remaking a destroyed Automaton requires 8 hours of uninterrupted work, plus 8 hours for each upgrade. In all other respects, this resembles the process for crafting a magic item. Upon creation, the engineer chooses the base form he wishes the Automaton to take from the following four types. This form may not be altered upon subsequent upgrades.  Then he adds to the base statistics bonuses based on his levels in engineer using Table 3-16: Automaton Base Statistics.

Class Level: The character’s engineer level. The engineer’s class levels stack with levels of any other classes that are entitled to an automaton for the purpose of determining the automaton’s statistics.
HD: This is the total number of 10 sided die (d10) Hit Dice the Automaton possesses. No Constitution modifier is applied to the Automaton’s hit points. The Automaton gets bonus hit points depending on its size: Medium 20 HP, Large 30 HP, Huge 40 HP.
BAB: This is the automaton’s base attack bonus. Automatons do not gain additional attacks using their natural attack for a high base attack bonus.
Saves: These are the automaton’s base saving throw bonuses. An automaton has poor saving throws.
Armor Bonus: The number noted here is the Automaton’s base total armor bonus. This number is modified by the Automaton’s base form. An Automaton cannot wear armor of any kind, as the armor interferes with the engineer’s operation of the Automaton. An engineer can enchant his Automaton’s body as if it were armor. In addition, magic items interfere with the engineer’s connection to his automaton. As a result, the engineer and his automaton share magic item slots. For example, if the engineer is wearing a ring, his automaton can wear no more than one ring. In case of a conflict, the items worn by the engineer remain active, and those used by the automaton become dormant. The automaton must possess the appropriate appendages to utilize a magic item.
Saves Bonus: Add this modifier as an equipment bonus to all of the Automaton’s saving throws.
Construct Traits: Automatons count as constructs and have the following two weaknesses:
* Vulnerable to Critical Hits: Whenever an automaton takes extra damage from a critical hit, it must make a DC 15 Fortitude save to avoid being stunned for 1 round. If it makes a successful saving throw, it is staggered for 1 round. The automaton remains immune to other sources of the stunned condition.
* Vulnerable to Lightning: Automatons take 150% as much damage as normal from lightning attacks, unless they are immune to lightning via other special defenses.
Armor Plating (Ex): At 1st level, the engineer chooses one of the following armor plating:
* Heavy Armor Plating: Grants the Automaton a +8 armor bonus to AC (with a max Dexterity bonus of 0), but with a -10 ft. movement speed and a -2 Dexterity to starting Dexterity score.
* Medium Armor Plating: Grants the Automaton a +4 armor bonus to AC (with a max Dexterity bonus of +4).
* Light Armor Plating: Grants the Automaton a +2 armor bonus to AC (with no max Dexterity penalty), movement speed increases by 10-ft., and a +2 Dexterity to starting Dexterity score.
Share Trick (Ex): At 2nd level, the engineer selects a trick he knows. The Automaton gains the benefit of this engineer trick. If the engineer chooses to share a gadget, the Automaton uses its own abilities to determine its effects with the exception of any saving throw DCs it requires, which are calculated from the engineer’s abilities. At 7th level and every 5 levels thereafter, the engineer can select an additional trick to share.
Ability Score Increase (Ex): The automaton adds +1 to any one of its ability scores.
Automaton Upgrade 1: An engineer may add this upgrade to their Automaton at 5th level. Adding the first upgrade to an Automaton creates a telepathic link between the engineer and his creation. They can mentally communicate across any distance as long as they remain on the same plane. Communicating in this way is a free action. The engineer may choose to increase his Automaton by one size category, granting it a +4 size bonus to Strength and 10 additional hit points based on its size. In addition, it gains DR 5/- and the engineer may add a +2 equipment bonus to Strength or Dexterity to his automaton.
Automaton Upgrade 2: An engineer may add this upgrade to their Automaton at 10th level. Adding the second upgrade allows the construct to make a second natural attack (as base form) during a full attack at the Automaton’s highest base attack bonus. It also gains a bonus feat from the following list, even if it would not normally qualify: Great Fortitude, Lightning Reflexes, Power Attack, or Toughness. In addition, the engineer may add a +2 equipment bonus to Strength or Dexterity to his automaton.
Automaton Upgrade 3: An engineer may add this upgrade to their Automaton at 15th level. Adding the third upgrade to the Automaton grants it the use of an elemental energy attack. At the time of the upgrade the engineer chooses from fire, ice or lightning elemental energy and picks either a 60 ft. line or 30 ft. cone, inflicting 4d6 points of damage plus an additional 1d6 points of damage for every 2 HD the Automaton possesses. A successful Reflex save (DC 10 + 1 per 2 HD the Automaton possesses + the engineer’s Intelligence modifier) halves the damage. This ability is usable once every 1d4 rounds and cannot be changed until the Automaton is upgraded again. In addition, the engineer can choose to increase his Automaton by one size category, granting it an additional +4 size bonus to Strength and 10 additional hit points based on its size. The maximum size of an Automaton is Huge. The Automaton also gains the Grab special attack on all of its slam attacks. In addition, the engineer may add a +2 equipment bonus to Strength or Dexterity to his automaton.
Automaton Master Upgrade: An engineer may add this upgrade to their Automaton at 20th level. Adding the fourth upgrade gives the Automaton an Intelligence score of 10. It can now act upon its own volition, but always according to the intention of its creator, gaining an identical alignment as the creator’s at the moment it gained sentience. It gains feats appropriate to its hit dice and 2 skill points per hit dice, treating any skill the engineer has ranks in as a class skill. The engineer may also increase the size of the Automaton once more (to a maximum of Huge), and change the Automaton’s elemental energy attack to earth, water or wind damage. In addition, the Automaton’s DR increases to 10/- and the engineer may add a +2 equipment bonus to Strength or Dexterity to his automaton.
=== Tinkering (Ex) ===
When it comes to tearing apart salvage, engineers are highly adept. By 2nd level, engineers become so used to tinkering with machinery that they come to understand the finer points of trap mechanisms. An engineer adds half of his engineer level to Perception skill checks made to locate traps and to Disable Device skill checks (minimum +1). An engineer can use Disable Device to disarm magic traps.
=== Combat Awareness (Ex) ===
At 2nd level, an engineer is ready to spring into action at a moment’s notice. He gains his Intelligence modifier as a bonus on all initiative rolls.
=== Engineer Tricks ===
At 2nd level, and every 2 levels thereafter, an engineer learns a technical innovation called an engineer trick. These engineer tricks come in three forms: augmentations, gadgets, or techniques. Unless otherwise noted, an engineer cannot select an individual engineer trick more than once. Some engineer tricks can only be received if the engineer has met certain prerequisites first, such as learning other engineer tricks. The DC of any saving throw called for by an engineer trick is equal to 10 + half of the engineer’s level + his Intelligence modifier.
* Augmentations are engineer tricks that enhance or otherwise add on to an Automaton.
* Gadgets are tangible items that engineers can craft. Generally, they are only usable a certain number of times per day and some require the engineer to provide some form of fuel. Only the engineer knows the peculiarities of their function, preventing others from using them. Unless otherwise noted, they are all Tiny items with AC 10 (when not being held); hardness 5 and 10 HP. If a gadget is lost or destroyed the engineer may spend 100 gil and 8 hours of work in order to rebuild it.
* Techniques are tricks that the engineer has learned that are not tied to any single item, however many require an item to be used in conjunction with them.
* A complete list of engineer tricks can be found here: Engineer Tricks
=== Rough and Ready (Ex) ===
At 3rd level, the engineer has trained with activating his gadgets under pressure that it becomes almost intuition to bring them to bear as his hands move with blinding speed. Once per day, the engineer can activate a single gadget that requires a standard action to activate as a swift action. At 7th level and every four levels beyond, the engineer can use this ability one additional time per day to a maximum of 4 times per day at 15th level.
=== Salvage (Ex) ===
At 3rd level, the engineer can salvage electrical and mechanical parts from destroyed vehicles, constructs, and airships. Salvaging a destroyed vehicle, construct, or airship takes time as noted in the table below. At the end of this time, the engineer makes a Perception check. If the check succeeds, he regains a number of uses to his repair ability equivalent to the number listed, as well as an equivalent insight bonus to a single chosen repair check. He cannot gain uses over his normal daily limit, and the bonus to repair checks is lost whenever the engineer refreshes his repair uses. A particular vehicle, construct, or airship can be successfully salvaged only once. Any further attempts to salvage the wreckage fail automatically.
== Table: Salvage (Vehicle, Construct, and Airship) ==
Size 	Time Required	Perception Check DC	Bonus
Tiny to Small	10 minutes 	10 	1
Medium 	30 minutes 	15 	2
Large 	1 hour 	20 	3
Huge 	3 hours 	25 	4
Gargantuan 	6 hours 	30 	5
Colossal 	12 hours 	35 	6
=== Demolish (Ex) ===
At 3rd level, an engineer has come to understand the key workings of mechanical devices and constructs so well that he can strike constructs or machinery for an additional +1d6 points of damage as long as he is using a blunt or piercing melee weapon. This increases by +1d6 every three levels after 3rd (6th, 9th, 12th, 15th, and 18th). In addition, the engineer can ignore up to 3 points of hardness/damage reduction against any construct. This increases by 3 every three levels after 3rd.
=== Jury-Rig (Ex) ===
At 4th level, the engineer gains Field Repair as a bonus feat, even if he does not meet the feat’s prerequisites. In addition, the engineer can make temporary repairs to broken technology on the fly. Jury-rigging a broken object (including a vehicle’s driving devices or engines) has a Craft DC equal to the Disable Device DC to disable a device of the same complexity, and requires the same amount of time; the Craft skill for this check must be relevant to the object being jury-rigged. If the check is successful, the object is relieved of the broken condition for up to 5 minutes. If a jury-rigged object takes any damage, it regains the broken condition. A jury-rigged object cannot benefit from this ability again until it has been repaired.
=== Support Droid (Ex) ===
At 4th level, an engineer can build a support droid. Support droids, like Automatons, are unintelligent constructs that follow the engineer’s instructions unfailingly. If a support droid is destroyed, the engineer must rebuild from scratch, costing him 100 gil per hit dice in material components, to rebuild his support droid. Remaking a destroyed support droid requires 8 hours of uninterrupted work.

Class Level: The character’s engineer level. The engineer’s class levels stack with levels of any other classes that are entitled to a support droid for the purpose of determining the support droid’s statistics.
HD: This is the total number of ten-sided (d10) Hit Dice the support droid possesses.
BAB: This is the support droid’s base attack bonus.
Saves: These are the support droid’s base saving throw bonuses. A support droid has poor saving throws.
Armor Bonus: The number noted here is the Support Droid’s base total armor bonus. This number is modified by the Support Droid’s base form. A Support Droid cannot wear armor of any kind, as the armor interferes with the engineer’s operation of the Support Droid. An engineer can enchant his Support Droid’s body as if it were armor.
Saves Bonus: Add this modifier to the Support Droid’s saving throws.
The support droid has no combat capabilities until level 12, but possesses two different support modes (Repair and Shield) at a 30 foot range.
* Repair (Ex): In Repair mode, the support droid will start repairing the automaton or any designated machinery the engineer commanded it to fix. The support droid repairs 1 damage per HD it possesses for a duration of 1 round per engineer level. While repairing, it can only take move actions. If all of the duration is used up for repairing, it must wait 1d4 rounds to regain the energy to repair.
* Shield (Ex): In Shield mode, the support droid will shield an ally with a protective barrier. The support droid encases the designated ally the engineer commanded it to with a protective barrier that does the following: +1 deflection bonus to AC, +1 morale bonus to saving throws, and DR 1/- per two HD it possesses for a duration of 1 round per engineer level. While shielding, it can only take move actions. If all of the duration is used up for shielding, it must wait 1d4 rounds to regain the energy to shield.
Fine-Tuning (Ex): The support droid gains the Evasion ability. If it makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, it instead takes no damage.
Support Droid Upgrade 1: An engineer may add this upgrade to their Support Droid at 8th level. Adding the first upgrade to a Support Droid creates a telepathic link between the engineer and his creation. They can mentally communicate across any distance as long as they remain on the same plane. Communicating in this way is a free action. The engineer may improve his Support Droid with the following abilities: Increase Flight Speed by 30 feet, Increase Dexterity Score by 2, Grant the Support Droid a Feat (must meet prerequisites), or Grant the Support Droid a DR of 1/-.
Improved Fine-Tuning (Ex): The support droid gains the Improved Evasion ability. Even if it fails a Reflex saving throw against an attack, it takes half damage.
Support Droid Upgrade 2: An engineer may add this upgrade to their Support Droid at 12th level. The Support Droid gains a new mode, Attack. This new combat mode allows the Support Droid to fire a ray of plasma with a range of 50 feet. In addition, the engineer may improve his Support Droid with any of the abilities from the 1st upgrade.
* Attack (Ex): In Attack mode, the support droid will start blasting a target creature the engineer commanded it to attack. The support droid uses a ranged touch attack and deals 1d6 points of half fire/half lightning damage per two HD it possesses for a duration of 1 round per engineer level. While attacking, it cannot take any other actions. If all of the duration is used up for attacking, it must wait 1d4 rounds to regain the energy to attack.
Stout Servant (Ex): The support droid is more durable and resilient. The support droid gains DR 5/-. This damage reduction stacks with any support droid upgrades.
Support Droid Upgrade 3: An engineer may add this upgrade to their Support Droid at 16th level. The Support Droid gains a new mode, Disrupt. This new combat mode allows the Support Droid to focus a beam of disruption energy that becomes a hindrance to any targeted spell-casters with a range of 50 feet. In addition, the engineer may improve his Support Droid with any of the abilities from the 1st upgrade.
* Disrupt (Ex): In Disrupt mode, the support droid will fire a concentrated beam of disruption energy at a target spell-caster the engineer commanded it to disrupt. The support droid causes the spell-caster to make concentration checks to cast spells with a –1 penalty for every two HD it possesses for a duration of 1 round per engineer level. In addition, the target must pay an additional MP for any successful casted spell. While disrupting, it can only take move actions. If all of the duration is used up for disrupting, it must wait 1d4 rounds to regain the energy to disrupt.
Support Droid Master Upgrade: An engineer may add this upgrade to their Support Droid at 20th level. Adding the fourth upgrade to the support droid increases its senses. The support droid can now see invisible creatures and objects. It has a darkvision of 120 feet as well as low-light vision. It also gains a force field. A force field sheathes the support droid in a thin layer of shimmering energy that grants 50 bonus hit points. All damage dealt to a support droid with an active force field is reduced from these hit points first. As long as the force field is active, the support droid is immune to critical hits. A force field has fast healing 10, but once its hit points are reduced to 0, the force field shuts down and does not reactivate for 24 hours. In addition, the engineer may improve his Support Droid with any of the abilities from the 1st upgrade.
=== Crafting Expertise ===
At 5th level, the engineer gains Master Craftsman as a bonus feat.
=== Quick Craft (Ex) ===
At 7th level, an engineer learns how to craft ordinary scratch-built items more quickly than normal. The engineer reduces the building time of ordinary objects and masterwork objects by half.
=== Durable Materials (Ex) ===
At 8th level, the engineer learns how to build for durability and toughness. Any item crafted by the engineer receives a bonus to hit points equal to the level of the engineer at the time of its creation.
=== Salvage Expert (Ex) ===
At 10th level, the engineer has gotten so good at keeping an eye out for spare parts that he can always decrease the cost of repairs or construction to his automaton or support droid by 25%. In addition, when using the Salvage ability, the engineer gains a competence bonus on his Perception checks equal to half of his engineer level.
=== Unflustered (Ex) ===
An 11th-level engineer can perform complicated tasks without provoking attacks of opportunity from adjacent foes. During any round in which the engineer uses the Craft, Disable Device, or Repair skill, he can first make a concentration check (DC 15, using the engineer’s level as his caster level) to use the desired skill without provoking attacks of opportunity.
=== Precise Timing (Ex) ===
At 13th level, the mechanical timing of a construct or automaton becomes incredibly predictable to someone intimate with how machines act and move. The engineer is now so familiar with this timing that he can never be caught flat-footed by a construct, and gains a +4 dodge bonus to AC against them as well.
=== Master Mechanic (Ex) ===
At 14th level, the engineer becomes fully experienced in the art of quick repairs and mechanical tinkering, even under pressure. The engineer can always take 10 on his jury-rig check or when using Disable Device, even when under adverse conditions. In addition, the engineer can make repairs or disable a device with masterful speed. He can make repairs on an object or vehicle in half the normal amount of time (repairing double the normal amount of damage per day of work). Furthermore, Simple devices can be disabled as a standard action, Tricky can be disabled in 1d2 rounds, and Difficult and Extreme devices can be disabled in 1d4+1 rounds.
=== Rapid Rebuild (Ex) ===
At 15th level, the engineer becomes faster at making things he is familiar with. As long as he has built something once in the past, he may rebuild it in half the time it would take to build normally. This ability only applies to the engineer's Automaton and Support droid, along with mundane crafting. 
=== Construct Expertise ===
At 15th level, the engineer gains the Craft Construct feat. The engineer does not need to meet the prerequisites for this feat. He uses his engineer levels as his effective caster level when creating constructs. The engineer can eschew spells needed to craft a construct, but the costs to craft are doubled, or he must have access to the prerequisite spells, either through use of a magical item or cast by another spellcaster.
=== Clockwork Mimicries (Ex) ===
At 16th level, an engineer can use his mechanical mastery to create clockwork mimicries of powerful magic items. Doing so takes 1 hour of uninterrupted work, and allows the engineer to create a wondrous item that functions for a number of hours per day equal to his engineer level. When creating such a clockwork item, the engineer must use materials worth an amount equal to the wondrous item’s construction cost. He need not meet any of the item’s other creation requirements. An engineer cannot create a mimicry of a consumable wondrous item or a wondrous item with finite charges, and he can have only one mimicry at a time. The clockwork item never functions as a wondrous item for any other creature.
=== Master Engineer (Ex) ===
At 17th level, the engineer’s expertise with dealing with crafting and repairing becomes exceedingly easy. The engineer is considered always taking 10 on any Craft and Repair checks. The engineer can also take 20 in half the time.
=== Primal Technomancy (Su) ===
Beginning at 19th level, an engineer can choose to use a scroll without consuming it or a wand/materia without expending a charge. Whenever he uses the Use Magic Device skill to activate a scroll or a wand he may add an additional +10 to the DC. If he fails this check the charge or scroll is expended as if he failed to activate the item. If he succeeds the scroll or wand is used but is not expended.
=== One With Machines (Ex) ===
At 20th level, the engineer floods his body with nanobots. The engineer becomes immune to poison and diseases. He also gains Fast Healing 5. In addition, the engineer may use the Repair ability upon himself as if he were a construct. Once per day, these nanobots can bring the engineer back to life as a Raise spell. The engineer will no longer takes penalties to his ability scores for aging. Any such penalties that he has already taken, however, remain in place. Bonuses still accrue. When the engineer’s natural life span is reached, the biology inside it fails, and its remaining systems become a construct with all of the same stats it had in life, but it no longer has independent thought.
