Biome Chest

Biome Chests are Hardmode Chests found within the Dungeon. The only Biome Chest currently in the Calamity Mod is the Astral Chest. It contains a Heavenfallen Stardisk, in addition to other miscellaneous items. While Astral Chests are placed during world creation, they are initially locked and can only be opened once a certain boss is defeated. Only one Astral Chest will spawn in a particular world.

To open an Astral Chest:


 * Defeat Astrum Aureus to allow the Astral Chest to be opened.
 * Return to the Dungeon and find the Astral Chest. Unlike vanilla biome chests, it does not require a key.
