Potion of UnDeath (3.5e Equipment)
From D&D Wiki
 Potion of UnDeath
This potion causes the drinker to fall into a never ending dreamless sleep in which he never ages or decays, never heals and never stirs. The drinker’s clothes and any gear remain with him in this state. His body becomes stiff like rigor mortis, and nearly indestructible, gaining immunity to all mortal attacks and spells. A Will Save DC 30 will prevent this slumber, and only a wish, miracle, divine intervention or some other powerful force can awaken him. Everyone knows that True Love’s Kiss is enough to break the spell.
This potion cannot be made by mortal means, and is typically granted by powerful fiends.
