Cardioamp

Pharmaceutical (potion), very rare

This potent drug can revive a recently deceased creature.

If administered within 1 minute of death, the creature may attempt a DC (11 plus 1 per round since death occurred) Constitution save. If successful, the character is restored to life as if by the revivify spell. Multiple doses can be administered to allow further chances of success. A creature subjected to multiple doses of cardioamp gains advantage on the second and subsequent saving throws.
