Biome Chests

Biome Chests are Hardmode chests found within the Dungeon. Each contains one specific rare, powerful weapon, in addition to other miscellaneous items. While Biome Chests are placed during world creation, they are initially locked and can only be opened with an appropriate Biome Key, which will only become available in Hardmode.

Only five / four  Biome Chests (one of each type) will spawn in a particular world. Each represents a biome found in the current world. There are six / five  types of Biome Chests in total, though a world will only contain one evil biome chest, a Crimson or Corruption variant, depending on which of those biomes the world contains.

In order to open a Biome Chest, the following steps are required to take:


 * 1) Kill Plantera to lift the curse from Biome Keys, allowing the keys to be used. As long as Plantera has not been killed, Biome Keys display the tooltip "".
 * 2) Obtain the appropriate Biome Key by killing enemies within their respective biome. On, the keys are crafted using Key Molds dropped by these enemies.
 * 3) Return to the Dungeon and find the appropriate chest for the key that was obtained.

Types
The chests also contain common items depending on the height they were found:


 * Surface
 * Underground
 * Caverns

Tips

 * Biome Key drops are extraordinarily rare (1/2500 is the chance of a key dropping from a defeated enemy in a biome). It is likely that thousands of enemies have to be defeated to see one drop. With the right equipment and some time, a Biome Key farm can be set up in the biome to get there sooner.
 * It is possible to get both the Corruption Chest and Crimson Chest if the player creates their world with the seed 05162020 which contains both world evils.

Trivia

 * The weapons found in each chest are based off of the four classes. The Vampire Knives and Scourge of the Corruptor are melee, Piranha Gun is ranged, Rainbow Gun is magic, and Staff of the Frost Hydra and the Desert Tiger Staff are summoning.
