Auto-Totem will save your life at the most critical moments by automatically equipping your next Totem of Undying.
In Minecraft, there are many dangers that can kill you not just once, but twice in rapid succession. You might find yourself drowning in a lava lake without enough time to reach land, or fighting the Wither, whose attacks can quickly erase your entire health pool.
With Auto-Totem, all you need to do is keep enough spare totems in your inventory; the mod handles the rest by automatically equipping them to keep you alive.
