Treasure ( Final Fantasy XII ) Treasures are randomly spawning objects that contain items or gil in " Final Fantasy XII " . Sometimes what appears to be a treasure , is a Mimic type monster , which attacks the player when they attempt to claim the treasure . When a player approaches a treasure two exclamation marks and the word " Treasure " appear on the screen . Game time is paused when picking a treasure and treasures can be claimed even in the middle of battle . Appearance . The treasure chests ' appearance varies depending on the area . In Rabanastre Lowtown the treasures appear as grey pots covered with cloth . In the deserts surrounding the treasures are brown pots with patterns . Most commonly treasures are the greenish - hued metallic containers found in dungeon areas . These are the chests Mimics imitate ; Mimics can take on various colorful appearances to set them apart from the normal treasures . In Tomb of Raithwall and Stilshrine of Miriam the treasures are traditional treasure chests , and in Giruvegan and in Great Crystals treasures are represented by large colored gemstones . Mimics . Mimics are a genus of monsters that take the appearance of treasures . They attack only when inspected . Two bosses in the game are also Mimics , the Mimic Queen and the superboss Omega Mark XII ; if the player ventures to Omega ' s lair before activating the Hunt for Yiazmat , Omega appears as a gigantic object that resembles a treasure chest that cannot be roused . The Rare Game Ithuno is a notable mimic , for the Deathbringer sword that can be stolen from it . Mechanics . The treasures randomly spawn with random content . Once a treasure has been collected , it can be re - spawned by going three areas away and returning ( only one zone in the " International Zodiac Job System " version ) . Certain treasures , however , contain specific items and do not respawn once opened . There are many random elements in place . First , a treasure has a certain chance to spawn ( to even appear ) . If the treasure spawns , it has a certain chance to give a variable amount of gil . If the treasure does not contain gil , it will contain items . When a treasure contains an item , it can be two possible items ; if the Diamond Armlet ( see below ) is not equipped the player has an equal chance of receiving either item . With the Diamond Armlet equipped one item is common ( 90 % chance ) and one item is rare . While some of the best items are hidden in respawning treasures the chance to get them can be brutally low , with as low as 0 . 1 % chance . Forbidden chests . In order to obtain the Zodiac Spear , the player must not claim certain treasure chests . If a " forbidden " chest is opened , Zodiac Spear can ' t be claimed at Necrohol of Nabudis . This feature is removed in the " International Zodiac Job System " version . Diamond Armlet . The accessory Diamond Armlet affects the item content when the treasure ( 1 ) spawns ( 2 ) is not gil . Two items are available , usually splitting the chance in a 90 - 10 fashion , with the 90 % chance usually being a Knot of Rust . In the " International Zodiac Job System " version , this becomes a 95 - 5 split . The two items can also be the same item . Cerobi Steppe is a notable area in the game , because all its treasures can have a rare item when the Diamond Armlet is equipped . In the original release , the Diamond Armlet increases the gil amount that chests give , but in the International Zodiac Job System version , the gil amount is unchanged . Urns . Urns are not like the other treasures . They are always on the same spot on the field and stay on the field after being opened , the top lid hovering mid - air . Urns are green and easy to spot . Usually they contain maps , or " candles " that reveal more of the area ' s map than what was available previously . The urn in the Tracks of the Beast area in the Giza Plains during the Rains contains the Feather of the Flock that lets the player speak to cockatrices . The only urn that can be missed permanently is in the Royal Palace of Rabanastre . Random number generator method . There is a way to retrieve the rare Diamond Armlet item from a treasure 100 % of the time when playing on the PlayStation 2 , which involves the game ' s pseudo - random number generator ( RNG ) . The RNG is not truly random , but a system known as the Mersenne Twister : a sequential list of numbers with a huge period ( 0 , 2 ^ 32 - 1 ) that the game uses to determine almost every random action . After the game is turned on , the RNG is set at the start , and each time the game wants to use random numbers it uses them in order . This system will also work when playing on PlayStation 3 , but the PS3 has a slightly different random number generator with more sequences . A way to recognize the RNG pattern is by hitting oneself while unarmed and looking for a pattern in which the character performs hit combos ( no Genji Glove equipped ) . Whether or not a character performs a hit combo is determined by the RNG , such as any other " random " process during gameplay , and there are ten possible RNG patterns . By noting when the hit combos occur one can determine what pattern of numbers are being used . Eventually , after around 80 random numbers have been used up , the player gets a 5 hit combo , and if a treasure is opened with the Diamond Armlet equipped immediately after getting the 5 hit combo , the treasure always yields the rare item . Getting just any 5 hit combo doesn ' t yet yield the rare item : the random number following the one that gives a 5 hit combo around the 80 hit mark is the one that gives the rare item . Hitting the correct number is difficult , because there are ten patterns the game can choose from and the game will shift from one pattern to another when certain actions are taken . The player needs to identify the pattern they are in and shift it if necessary in order to produce the required 5 hit combo . The trick can be performed at any point though it is best the character does not deal damage when they hit themselves , as the character will need to do a lot of hitting in order to get the correct combo , so even while doing tiny damage their HP will be eaten away . To prevent damage one should avoid purchasing Brawler augments on the License Board and equip a good armor . If Brawler augments have already been purchased the character can equip a shield because that will negate the Brawler , but then the player needs to equip the Cameo Belt so not to block any attacks ( and then remember to equip Diamond Armlet before opening the treasure ) . The console needs to be turned off before setting off for a treasure . Soft reset does not suffice . With a fresh game the player needs to make their way to a treasure that can contain a rare item and they are ready to start hitting . In order to keep the RNG as " fresh " as possible the player is best not dealing damage or using magick , but enemies can be dispatched either with the Nihopalaoa + Phoenix Down combo , or the Immobilize glitch . Casting Cure or Curaga makes the pattern shift to the next one . Here are the four pointers and the required action to achieve the required 5 hit combo . 2 hit combo appears from 17 - 28 hits . The player must then cast Cure once , which leads to the 4 hit and then the 5 hit combo , " or " it will lead to one of the other three pointers . 3 hit combo appears from 30 - 36 hits . Player must then cast Cure four times , which leads to one of two possibilities : 2 hit combo appears from 40 - 64 hits at which point the player must cast Cure five times , which will be followed by the 5 hit combo , usually after another 19 hits , though , if the 2 hit combo came in 40 - 45 hits , it is likely the 4 hit combo will come first , followed 28 hits later by the 5 hit combo . 3 hit combo appears from 50 - 64 hits , at which point the player must cast Cure three times , which is followed by the 5 hit combo . There are three other possibilities that may happen that don ' t require any action : Apart from the four pointers and the three other possibilities that require no player action , any other combo can be ignored . By this method it is possible to get the rare item from any treasure with a few exceptions : Places like Lowtown and Balfonheim are excluded because one can ' t do hit combos in towns . Things that affect the RNG : Things that don ' t affect the RNG : RNG Method and Spreadsheets . A new method was developed that lays bare secrets of the RNG and allows players to not only accurately know their location in the RNG , but to use this information to precisely affect game outcomes . By using the Cure spell , which advances the RNG by one number each use , players can find their place in the RNG with startling accuracy . Spreadsheets are needed to help players determine their location within the RNG , detailing the first 60 , 000 numbers the PS2 uses for random number calculations . The spreadsheets contain lots of information and can apply the results of the RNG to stealing , poaching , using Sight Unseeing and spawning enemies in addition to opening chests . " The Information above is from Final Fantasy XII Treasure Manipulation FAQ / Guide by FF12GrandMaster " Development . " Final Fantasy XII " is the first offline main series " Final Fantasy " game where the outcome of treasures is random . This was done deliberately as the developers wanted to install the kind of feeling of destiny , that the players will either find good treasure or not , and they will just have to keep going regardless , bringing a different kind of element to the gameplay . Hiroyuki Itō , who was appointed as the game ' s director along with Hiroshi Minagawa after Yasumi Matsuno left the project , has reflected that the idea ended up not working perfectly . The " Final Fantasy XII International Zodiac Job System " version has around 1 . 5x the treasures as the original . The reason given for this is that the player is stuck with fixed jobs with no way to utilize all jobs in a single playthrough , leading to a situation where the player will undoubtedly acquire treasures that are useless for them . To alleviate player frustration a greater number of treasures was added into the game . The concept of forbidden chests was removed in the " Zodiac Job System " version as well , but there is a treasure on the float deck of an airship that appears 1 % of the time , and is a Seitengrat ( a new ultimate bow added to the game ) 0 . 01 % of the time . The treasure is actually invisible , so the player will only find it if they bump into it . If the player acquires the Seitengrat an arrow will appear in the sky in the Cerobi Steppe suspended a few feet in the air . In the " Zodiac Job System " versions half the game ' s magick and technicks are found in treasure chests , and these were mainly guaranteed to appear . Because the Cerobi Steppe is an optional location some low - probability treasure , and chests that only contain good items with the Diamond Armlet equipped , were placed there . Some of the Cerobi Steppe treasures are guaranteed to be gil , and in those cases , the numbers are from the multiplication table , i . e . 6636 gil because 6 x 6 = 36 .
