Totem of Undying

"... The Woodland Mansion houses many treasures worth the risk - not least of which resides within the robes of the Evoker himself. Best him in combat and he will drop a Totem of Undying - a magic relic that, if equipped during some fatal calamity, will bring the player back from the brink of death!"

- Marsh Davies

The totem of undying is a rare item which can save a player from death.

Obtaining
The totem of undying can only be obtained from the spell-casting evoker. Only one totem will be dropped each time, and cannot be increased with the Looting enchantment.

Usage
If the player is holding a totem of undying in their off-hand or main-hand slot and receives otherwise fatal damage, the totem will prevent the player from dying. The totem of undying must be in the player's off-hand or main-hand for it to work — it will not work if it is in the hotbar, unless selected. The totem can only be used once; it will disappear after use. They do not save the player from death caused by void damage (and, by extension, the command).

Effect
When activated, restores, removes all existing status effects, then grants 40 seconds of II, 45 seconds of  II and 5 seconds of  II. An animation will play where the totem of undying appears to hover in front of the player's screen, similar to the animation when a player encounters an elder guardian.

Trivia

 * If a mob is holding a totem of undying, the mob will also resurrect upon death and the sound effect will play. However, the animation will not show up.
 * In Bedrock Edition, if an undead mob is holding a totem of undying, they will resurrect upon death, but will rapidly take damage because of the Regeneration effect.
