Info

  • Penance is Harrow’s ability 2.
  • Sacrifice Shields to boost Reload Speed, and Fire Rate while converting damage inflicted on enemies into health for Harrow and nearby allies.
  • Use it with the rest of the kit — especially Condemn, Thurible — instead of casting it in isolation.
  • Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

Tips & Tricks

  • Read the battlefield first — cast Penance when it actually solves the room, not on cooldown habit.
  • Pair Penance with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Penance still carries without strip, Viral, or a squad buff.
  • If you never press 2, it’s the first Helminth candidate on Harrow.

Mission Use Cases

MissionHow to Use It
Steel Path Survival / Defense / DisruptionTest whether Penance still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Penance to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Penance only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Penance is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe.

Comparisons

  • VS

    Vs similar tools on other frames — Penance is tuned for Harrow’s loop — don’t judge it as a standalone subsume without the rest of the kit.
