Hunter Adrenaline

Hunter Adrenaline is a set mod dropped from the Hemocyte during Operation: Plague Star and Ghoul Purge bounties that converts a percentage of Health damage received into Energy.

Stats

The amount of Energy gained from damage taken to health is affected by Warframe Armor.
Stacks with Rage for a total of 85% damage conversion.

Applies to Status Effects that deal damage over time and damage that bypasses shields.
Does not apply to the following sources of damage;
- Self-inflicted damage (Using explosive weapons in close quarters, for example),
- Laser traps encountered in the Orokin Void and Orokin Derelicts,
- Health lost due to the Vampire Nightmare Mode modifier, or health drained in Survival missions by falling to 0% life support

Hunter Adrenaline gains more mileage when equipped to Warframes with high Health such as Ash, Inaros, Mesa, Saryn or Nidus.
- In particular, Inaros and Nidus benefit greatly from Hunter Adrenaline due to their lack of shields and significantly high health.
Hunter Adrenaline can be used alongside healing effects to create a renewable source of energy.
- Examples of healing include Life Strike for melee weapons, Valkyr's Hysteria ability, and the healing abilities of Trinity and Oberon.
  - Note that Trinity already possesses a primary means of generating energy.
- Many Warframe ability Augments (such as Saryn's Regenerative Molt) create healing effects which can be employed in the same fashion.
- Beware of high amounts of burst damage which may overwhelm a Warframe before they can heal themselves.
Hunter Adrenaline increases the time Wukong can actively resist death via Defy.
If the player has Quick Thinking equipped and suffers lethal damage, the gain in energy will be converted back over as emergency health.
When hunting for vaults in the Orokin Derelict, or even outside of the derelict, equipping the Decaying Dragon Key handicap to sacrifice shields will reduce the time needed before Hunter Adrenaline can take effect.
