The Totem of Deferred Death is a dark alternative to the vanilla Totem of Undying.
When a fatal blow would kill the player, the totem activates automatically, saving them from death and granting one full minute of complete protection. During this time, the player becomes immune to all damage and can continue fighting, escaping, or completing their objective.
However, the death cannot be avoided.
After 60 seconds, the protection ends and the player dies instantly, no matter how much health, armor, or equipment they have.
The totem can be used to save things from burning in lava or to record the coordinates of death.
