|Rank||HP Regen||Invulnerability Period||Cost|
- 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 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.
