  • This mod can be acquired by attaining the rank of Genius under Cephalon Suda, or the rank of Flawless under New Loka, and spending ReputationLargeBlack25,000 to purchase.


  • Heals ally players, Kubrows, and other allies by a percentage of max health every 1.5 seconds. Heals self by 10% of max health every 1.5 seconds.
  • Each instance of healing for every wounded target will consume 5 energy from Hydroid.
  • Heals Hydroid and his Companion, along with normal and syndicate Specters. Note however, that the entity being healed must be touching the pool, meaning Cephalon Suda's Shield Osprey reward cannot be healed by the ability unless it is forced onto the ground long enough, which is extremely unlikely and rare to happen.
  • Cannot revive downed players.
