 ====== Treasure randomization ====== ====== Treasure randomization ======
  
 +There are several randomization levels to customize the contents of the treasure chests throughout the world. (Note that "​treasure chests"​ also refers to treasures in pots, bookshelves,​ etc.)
 +
 +Note that all randomization levels treat trapped chests (ie. those containing monsters) differently from untrapped chests. Except where otherwise noted, the discussion below generally refers to untrapped chests.
 +
 +Additionally,​ the chests containing the Rat Tail and Ribbons in vanilla FF4 are handled by the key item randomizer logic, and are not affected by the behaviors detailed here.
 +
 +===== Vanilla treasures =====
 +
 +Under ''​Tvanilla'',​ chests contain the same items as they did in the Japanese version of FF4. Trapped chests deliver the same rewards as in the Japanese version of FF4 as well.
 +
 +If Japanese-exclusive items are excluded from treasure chests (see below), chest contents match the US version of Final Fantasy IV instead.
 +
 +===== Shuffled treasures =====
 +
 +Under ''​Tshuffle'',​ chests overall contain the same contents as in ''​Tvanilla'',​ but they are shuffled so they appear in different locations.
 +
 +Untrapped chests are shuffled separately from trapped chests. ​ Untrapped chest contents from the overworld tend to remain in the overworld, and likewise for non-overworld chests. Specifically:​
 +  * Overworld chest contents are placed in pool 1, and underworld/​moon chest contents are placed in pool 2.
 +  * 50% of each pool is extracted and combined into pool 3.
 +  * The pool 3 items are randomly redistributed back into pools 1 and 2, to restore them to their original sizes.
 +  * Pool 1 treasures are randomly assigned to overworld chests, and pool 2 treasures are randomly assigned to underworld and moon chests.
 +
 +Trapped chest rewards are shuffled amongst themselves without regards to location.
 +
 +===== Randomized treasures =====
 +
 +''​Tstandard'',​ ''​Tpro'',​ ''​Twild''​ and ''​Twildish''​ select random contents to populate each chest, with varying distributions.
 +
 +''​Tstandard''​ and ''​Twild''​ are unweighted distributions. That is, the location of the chest does not affect the probability of its contents. ​
 +  * Under ''​Tstandard'',​ each chest contains a random item from tiers 1-5.
 +  * Under ''​Twild'',​ each chest contains a random item from tiers 1-7.
 +  * Under both, trapped chests contain a random item from tiers 5-7.
 +
 +''​Tpro''​ and ''​Twildish''​ are weighted distributions;​ chests in different locations have different probabilities of containing strong vs. weak items. Trapped chests also have their own distributions. For full probability information,​ see [[Treasure probability curves]].
 +
 +===== Empty treasures =====
 +
 +Players seeking a challenge can use the ''​Tempty''​ flag to remove all treasures from untrapped chests. Trapped chests are treated the same as in ''​Tpro''​.
 +
 +For a similar, less extensive effect, the other randomization levels may be combined with a ''​Tsparse:''​ flag, which removes all but a specified percentage of untrapped chests.
 +
 +To reduce busywork, chests rendered empty by ''​Tempty''​ or ''​Tsparse''​ begin the game already opened, so you can tell at a glance whether they need to be checked.
 +
 +===== Forced treasures =====
 +
 +If other flags force items into treasure chests (for example, a Dark Matter Hunt), those choices are made after the randomization is applied, and overwrite the previous chest contents.
 +
 +===== Other treasure flags =====
 +
 +Setting ''​Tno:​j''​ will exclude Japanese-version exclusive items from appearing in chests.
 +
 +Normally, tier 1 items in chests are replaced with an equivalent amount of GP, to prevent cluttering up the inventory with weak items. Enable the ''​Tjunk''​ flag to keep tier 1 items as they are.
 +
 +===== Trapped chest relocation =====
 +
 +Trapped chests are randomly relocated within their respective dungeons. For example, Eblan Castle contains three trapped chests with the same fights as usual, just in different locations.
 +
 +Note that for technical reasons, the trapped chest in Upper Bab-il will always be positioned somewhere before the drop to the underworld.
 +
 +Setting the ''​-vanilla:​traps''​ flag will force trapped chests to remain in their original positions.
