Treasure Bag

Treasure Bags are grab bag-like items obtained in Expert Mode and Master Mode as a reward for defeating bosses. The contents of Treasure Bags depend on the boss it comes from, and are opened by right-clicking while in the player's inventory or left-clicking while selected in the player's hotbar. In multiplayer, each player that deals damage to the boss receives one Treasure Bag upon defeating it.

Each Treasure Bag contains the boss's usual drops from Classic Mode, along with one Expert Mode-exclusive item. Treasure Bags dropped from Hardmode bosses additionally have a 1/16 (6.25%) chance to contain one random set of developer items.

Origins adds Master Mode-exclusive items, which also appear in treasure bags and share a drop pool with the Expert Mode-exclusive items that already exist.
