  • Regen is a universal mod for both aggro-attracting sentinels (Dethcube) along with utility sentinels (Carrier and Shade) as they are able to be caught within line of fire from area-of-effect attacks.
  • Regen synergizes well with the Sentinel's Mod TT 20px.png Enhanced Vitality, as the modified maximum health is recognized as the current maximum health for the Regen ability to provide.


  • Gives the Sentinel 100 affinity for activating this ability.
  • This mod does not actually revive the Sentinel, but instead it automatically heals the Sentinel a certain percent depending on the fusion rank when it reaches 0 health.
