Umbral Vitality

Umbral Vitality is the Umbra variant of Vitality and a legendary Warframe mod that raises max health by 100% at max rank and adds Tau resistance. It is considered the same mod as its common counterpart, so you cannot equip both. It also belongs to the Umbral set.

It is given at the penultimate mission of The Sacrifice, automatically ranked to level 5, and additional unranked copies are sold by Cephalon Simaris for 100,000 standing. It is untradeable and cannot be transmuted. Equip it with Umbral Fiber and Umbral Intensify to boost the set bonus.

Umbral Vitality was added with Update 23.0 (June 2018).
