This datapack adds Terraria style boss Treasure Bags to Minecraft. There are Treasure Bags for the Ender Dragon, the Wither, and the Elder Guardian.

Optifine is NOT required for this resource pack/datapack combination.

As there is no way from what I can tell to detect an empty bundle, there is a bug where if you do not open the bundles in the order that the slots are numbered in the second screenshot, you will lose some loot and end up with empty bundles that look like the Treasure Bags. However, bundles in the offhand slot should be opened last.

*NOTE: The nether star is not included in the Wither's vanilla loot table. It will still drop from the Wither, separate from its Treasure Bag.*
