Bauble of Undying
This mod replaces the Totem of Undying with a version that can be equipped as a Baubles charm. It will render on the player's chest, and behave just like it would when held. This was made because I got fed up of the holding requirement implemented by Mojang. The worst feeling is forgetting to switch to this when you're about to die in a fight; now you can have it always at the ready, and taking up none of your regular inventory space. The totems can be right-clicked in-hand to equip it into the charm slot if there is space for it.
