Baubles Mod 1.12.2/1.11.2 is a small addon mod and API that is intended to be used by other mods to add additional inventory slots to a character. It adds 7 new slots: an amulet, belt, head, body, charm and two rings.
It adds 4 new slots: an amulet, belt and two rings slots. The baubles inventory is accessed by pressing the ‘b’ hotkey. It is probably a good idea to remap your normal inventory hotkey to the baubles inventory if you are going to be accessing it a lot.
The ring gives a boost to mining speed when worn. (The potions are Swiftness II potions)
