Undead Totem

This Totem can be rarely dropped by a zombie/husk/drowned/zombified piglin.

When in the main hand or the off-hand, at the moment of a player's death, it will activate, saving the player restoring his health and giving fire resistance for 1 minute. However, the player will have the condition "Undead": this means that it will burn in sunlight, won't regenerate health, and won't be able to trade with Villagers and piglins, that will be scared and run away, and will be affected by the Smite enchantment. However, the player won't have any hunger bar when undead, and any undead mob will be neutral towards the player. This doesn't include creepers and spiders.

To cure the "Undead" condition,  we will have to drink a Weakness 2 potion, and then eat a golden apple: after 5 minutes, we will turn back humans, and won't have the "Undead" condition anymore.
