Always prepared to sacrifice. This monastic Warframe uses the Void to bolster allies' defenses and amplify their lethality.

This is Harrow, the monastic, the ritualist.

Harrow is suffragan to the Void. Will you believe, Tenno?

Release Date: June 28th, 2017

Dauntless and devout, the dark priest Harrow bestows upon his coven three virtues: salvation through sacrifice, redemption through vengeance, and ascension through defiance.

Nemeses beware, for only death awaits. Enchain the tainted, silence their heresy, and deliver their tormented souls unto the Void's embrace. Harrow was absolved in Update 21.0.

  • If Harrow wields his signature PriestPistol Knell, the weapon's magazine size is increased by 1 round, for a total of 2 rounds.
  • Harrow holds the highest Overshield capacity of all Warframes in the game: 2,400.
  • Harrow's Condemn130xDark Condemn seems to disable Electricity b Electricity status effects (may be bug).


  • Harrow can achieve the second-highest total shield value out of all Warframes (behind HildrynIcon272 Hildryn) at 4,110 by combining ​Mod TT 20pxRedirection, ​Mod TT 20pxPrimed Vigor, ​Mod TT 20pxAugur Accord, and his maximum Overshields. This number can potentially be higher with other buffs that increase shield capacity (such as ​Mod TT 20pxShield Charger​ and Sequence).
  • For DEGrinlok Grinlok users, Harrow may offer quite a lot of synergy when considering critical chance Riven Mods and Mod TT 20pxDeadly Sequence. Apart from being a decently accurate rifle, the mentioned mods synergize very well with Condemn130xDark Condemn, Penance130xDark Penance, and Covenant130xDark Covenant. This is because they grant better critical chance and the Sequence effect buffs the maximum shields by 50% and hence allows Penance to last longer, Condemn to be more effective, and Covenant to yield better returns with criticals. Also the Radiation b Radiation proc from the Sequence area of effect negates Ancient Healer auras allowing him to leech more health with Penance.


  • Harrow means "to traumatize or torment."
    • It originally referred to a farming tool – a frame covered in spikes—which was dragged across soil in order to remove weeds, break up clods of dirt, and cover-up seeds. A 'harrowing' experience has come to mean one where an individual undergoes significant trauma but comes out of it purified.
    • In a particular interpretation of Christianity, Christ's descent into Sheol in order to retrieve the souls of all the individuals who died between the beginning of the world and his sacrifice, excluding the damned, is referred to as the Harrowing of Hell.
  • The name of Harrow's abilities refer to various aspects of Catholicism.
    • To be damned in the Catholic faith is to be condemned to hell as punishment for mortal sins after death.
    • Penance is an alternate name for the Sacrament of Reconciliation in the Catholic Church.
    • A thurible is a metal censer suspended from chains, in which incense is burned. A Thurible is usually used during Mass.
    • A covenant is an agreement made by God with a religious community or with humanity in general.
  • Similar to ExcaliburIcon272 Excalibur's Exalted Blade, IvaraIcon272 Ivara's Artemis Bow, and WukongIcon272 Wukong's EWIronStaff Iron Staff, Harrow's iconic object of power, his thurible, is shown during the casting animations for his abilities.
    • Harrow's thurible is also visible during his Noble and Agile idle animations. However, if the animations are equipped on a different Warframe, the thurible will not be visible.
  • Harrow is the first Warframe to have an associated and named original Operator, Rell.
    • Also, he is the first original Warframe to have been active, since the Orokin Empire, until the current timeline.
    • Since Rell is said to be a Tenno outcast, where even Lotus didn't know about him, it is not known how Harrow was created and by who.
  • Harrow is one of the only 3 Warframes whose component blueprints are dropped from non-boss enemies.
    • In Harrow's case, there is only the Chassis that is dropped by enemies.
    • The other two are AshIcon272 Ash and OberonIcon272 Oberon.
  • Harrow is the second Warframe to be controlled by an entity other than the Tenno, after ChromaIcon272 Chroma. He was hostile toward the players, like Chroma, as well.
    • Unlike Chroma, there is an explanation about how and why Harrow came to be in such a state. See Chains of Harrow quest.
  • Upon waiting a short time whilst in Harrow's abilities page, players will hear the familiar "Rap Tap Tap" of The Man in The Wall.
  • Harrow's Noble Animation standing stance mimics a military "parade rest," and his Noble primary weapon idle movement closely resembles the spinning rifle tricks performed by military honor guards.
