Vecna's Reanimation (5e Spell)
From D&D Wiki
|7th-level Necromancy (ritual)
|V, S, M (A glass eye worth at least 100 gp, which the spell consumes)
You burn up the glass eye used in the spell's casting and turn it into an undead spirit that watches over you for the duration. If you die before the spell ends, the spirit sacrifices itself in your place, raising you from the dead with hit points equal to half of your maximum hit points.
This spell also neutralizes any poisons and cures any diseases, curses, or other similar effects you had at the time you died that would cause you to die again within the next hour of you returning to life. It does not neutralize any other effects.
This spell closes all mortal wounds, but it can't bring back missing body parts. If you're missing any parts essential for survival — such as your head — the spirit will bring you back to life and you will in all likelihood die all the same.
