    • The amount of shields to be drained is determined on activation. Shield points from Condemn130xWhite Condemn will not be drained if gained during Penance's casting animation.
    • Each time Harrow flagellates himself, 50% of the total shield points are subtracted.
  • Can be recast while active to stack extra duration to the remaining time.

  • Harrow's wounds on his back from flagellation emit piercing light in his chosen Warframe energy color.
  • Casting Penance stops all of Harrow's movement and actions.

Tips & Tricks

  • Mod for a higher shield pool to gain more extra duration for Penance by default.
  • Harrow can opt to choose to build Penance over Ability Strength for quick bursts of fire rate and lifesteal, or Ability Duration for sustained fire rate and reduced need to deplete Shields to recast. While the former is useful in quick missions and Assassination runs, the latter can be useful in endless missions such as Survival, considering the added protection afforded by a Duration-based Covenant130xWhite Covenant.
  • Use Condemn130xWhite Condemn to quickly replenish shields and Overshields to fuel Penance' extra duration.
  • Build up your shield and Overshield pool again after casting Penance, then recast Penance to stack extra duration onto your remaining time to keep the ability active much longer.
  • Mod TT 20px Guardian, Mod TT 20px Protect, Mod TT 20px Brief Respite & ArcaneBarrier Arcane Barrier are useful for this ability as they are capable of restoring Harrow's shields.
  • Cast Covenant130xWhite Covenant before or after using Penance to protect yourself from damage when you are at your most vulnerable state.
  • The fire rate bonus also affects melee weapons.
  • Can reduce recharge delay for Cycron Cycron or a Kitgun equipped with PaxCharge Pax Charge, however, it does not affect recharge rate.
