Capacitance is a Warframe Augment Mod for VoltIcon272.png Volt that converts a percentage of damage dealt by Discharge130xDark.png Discharge into shields, split between himself and allies.


Rank Shield Bonus Cost
0 1.5% 6
1 2% 7
2 2.5% 8
3 3% 9


  • This mod can be acquired by attaining the rank of Maxim under the Arbiters of Hexis, or the rank of Exalted under the Red Veil, and spending ReputationBlackx64.png 25,000 to purchase.


  • Can create Overshields.
  • Affected allies includes all Warframes, Companions, Eidolon Lures, summoned allied units such as Specters, allied Invasion units, Hostages, Kavor Defectors, Sortie and Arbitrations Defense Operatives, and Defense Objects.
    • On Defense Objects, their shield gain is capped at 250, and do not gain overshields.
  • Shield bonus is affected by Ability Strength, but the amount per second also seems to be an average instead of a static number, and can fluctuate for each tick dealt on enemies even if the damage remains the same.
  • This augment works best the more enemies there are in a group, due to how Discharge works, zapping each other and increasing the amount of bulk shield obtained within the first moments of the cast.


  • Mods like Mod TT 20px.png Fast Deflection and Mod TT 20px.png Fortitude can be used to increase Volt's shield recharge rate, allowing overshields to add up sooner.
  • Enemies trapped in a vortex of Vauban's Bastille130xDark.png Bastille will all be hit at the same time, and will shock every enemy inside at once causing potentially massive bulks of shields each second as well as increased DPS of the ability. This also allows a low Power Range build to be viable.
  • Casting ElectricShield130xDark.png Electric Shield before casting can prevent some damage to Volt and his allies when casting, as the base ability prevents Volt from moving, and may only slowly regenerate shielding.
