Back Slots requires Curios API: Curios API

Config for ModPack / Server Owners:

"Format: "modid:itemid,rotX,rotY,rotZ,scale,transX,transY,transZ"", "Example: "minecraft:shield,180,0,0,2.0,0,0,0.0"" This allows for any configured item to be displayed however you want on the player. I plan to add a data driven aswell for mod developers that will allow for native support without utilizing the config, but currently this is all thats implemented at the moment.

Features:

Adds the backslot via Curious, you can put any item in the backslot and it will display on your back. Quick Swap key allows for the player to swap whatevers in their main hand into their back and vice versa. This allows for quick switching mid combat. !Curious Back Slot
