Curio of Undying (Forge) Mod 1.16.5/1.15.2/1.14.4 is the next version of the mod for your MC game. This mod does nothing but add a totem slot for your game. It will be in your inventory, and you will never need to hold the totem in your hand.
In the old version, players can only benefit from totems when holding them in their hands. But right now, all they need is to use this mod to have a new slot in the inventory. And then they can have all the help from the totem even when they are dead.
Curio of Undying (Forge) Mod will not take any slot from your inventory. It will add to your game a whole new slot and use it as an extra slot. Not like the old mod, you will have a slot on the hot bar. This slot will now lay in your inventory. For better control!
Minecraft Forge will be a needed mod for your game. Add that one, too, and make your game be more fun!
