Biome Chests

Dungeon Chests are chests found in the Dungeon representative of the various biomes in Terraria. Like other chests in Terraria, they are placed during world creation; however, they can be opened only with a Dungeon Key from the appropriate biome, which can only be found by defeating enemies within the respective biomes once Hardmode is activated.

Hence, unless a key is obtained from another player or through inventory editing, the chests will be impossible to open before Hardmode. Instead, a character will need to return to the Dungeon once Hardmode is activated after obtaining the correct Dungeon Key for a chest (and face Hardmode Dungeon enemies) before being able to open a chest.

Dungeon Key Mold drops are extremely rare (1/4000 chance of a key mold dropping from a defeated enemy in a biome); however, there are typically only one of each type of chest in each world.

Loot
Besides the rare items listed here, the chests also contain common items depending on the height they were found:


 * Surface
 * Underground
 * Caverns.

Because Corruption and The Crimson are exclusive to each world, a single world cannot contain both Corruption Chest and Crimson Chest.
