Corrupted Ancient

An Orokin-controlled Infested Ancient Healer. They act exactly the same as normal Ancient Healers, regularly healing all other Corrupted units nearby, but are Fossilized, unlike their normal counterparts. And as regular Ancient Healers, they can be mind controlled by Nyx, or brought back as a Shadows Of The Dead Clone by Nekros to heal you and your teammates, giving you 100 health per pulse.

Trivia

 * As the Ancient Healer is the only type of Infested to be found in the void, and may have been trapped there for centuries, this leads us to belive that Ancient Healers are the oldest form of Technocyte Plague.
