Treasure Bags are consumable items obtained in Expert Mode and Master Mode as a reward for defeating bosses. Its contents depend on the boss it comes from. It is opened by either right-clicking it inside the inventory or using it while it is in your hand. In multiplayer, each player that deals damage to the boss receives one Treasure Bag upon completion. Treasure Bags are client-side and will despawn upon exiting the world.
In addition to the above, all Treasure Bags from Hardmode bosses (except Queen Slime's) have a 5% chance to contain a random set of developer items, meaning that each set has a 0.28% chance of being in a Hardmode boss Treasure Bag. Obtaining a Treasure Bag in an Expert world, then opening the bag in a Normal world will retain the Treasure Bag's chance to yield developer items.
The Moon Lord's Treasure Bag is the only one to include both more than two Expert mode items and no money.
Betsy's Treasure Bag is the only (obtainable) bag that does not have an Expert mode item. It is also (along with the Moon Lord's) one of the only ones to contain no money, replacing coins with Defender Medals.
The Lunatic Cultist, Ogre, and Dark Mage have sprites for a Treasure Bag, even though they do not drop one.
Unlike the Lunatic Cultist's Treasure Bag, the Ogre and Dark Mage do not have data assigned to their Treasure Bags, as attempting to hack in either one will cause them to disappear from the player's inventory instantly.
Queen Slime's Treasure Bag is the only Treasure Bag to not have the tooltip "Right Click to open"
Additionally, it is the only hardmode Treasure Bag to not drop developer items.
Treasure Bags are referred to as "Boss Bag" in their Item IDs.
