Congratulations! You are now standing in a storage room with thousands of chests.
Some maps include chests containing "developer items" or unused content. Do not grab Calamitas' Soul or Yharim's Crystal unless you want to break your game's balance entirely. terraria calamity mod all items map download free
The most famous and widely updated "All Items" map for Calamity is the "Calamity Builder's Workshop" (sometimes called Draedon's Vault or Fabsol's Cache). Congratulations
