Energy Siphon is an aura mod that regenerates the energy pools of a given squad.


Rank Energy Regen/Second Cost *
0 +0.1 -2
1 +0.2 -3
2 +0.3 -4
3 +0.4 -5
4 +0.5 -6
5 +0.6 -7

* Aura mods increase the amount of Mod Capacity



  • Can be stacked with other instances of Energy Siphon for a total of 2.4 energy regeneration per second in regular missions.
    • It can also stack with Zenurik's Energizing Dash, reaching a total of 8.4 energy regeneration per second while in a party.
    • Adding Mod TT 20px.png Coaction Drift on a 4 player cell will give ~2.86 energy regeneration per second, stack with Zenurik's Energizing Dash ~8.86.
  • If the player uses a channeled ability such as Absorb130xDark.png Absorb or Undertow130xDark.png Undertow, they will not regenerate energy until they deactivate that ability.
    • This only applies to channeled abilities with a constant energy drain, abilities with variable energy drain such as ArtemisBow130xDark.png Artemis Bow, PacifyProvoke130xDark.png Pacify & Provoke and Desecrate130xDark.png Desecrate do not interrupt energy siphon.
  • The Sortie "Energy Reduction" condition also reduces the rate of energy regeneration.
  • Being idle for 2 minutes will cause the regeneration to stop.
  • Using only certain abilities off of cooldown, with the right build and duration/efficiency, Energy Siphon can allow a player to regenerate the energy spent on the ability before it ends, thus letting them use that ability infinitely.


Patch History[]

Update 29.10 (2021-03-19)

  • Hildryn will no longer gain Shield strength from features that give Energy-per-second regeneration. She will still convert Energy pickups into extra Shield strength. This fixes an unintended mechanic where things like Energy Siphon would make her completely invulnerable during combat.

Hotfix 29.0.6 (2020-09-01)

  • Fixed Energy Siphon on Hildryn resulting in her Pillage Overshields being reverted.

Hotfix 19.11.5 (2017-02-28)

  • Fixed an issue with Warframe Auras not stacking in missions.

Hotfix 19.3.2 (2016-12-14)

  • Fixed Auras applying twice when using a Focus ability.
