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.
Harrow's main blueprint is awarded upon completion of the Chains of Harrow quest. The Chassis blueprint is acquired from Void Fissure enemies, the Neuroptics blueprint can be found from Rotation C vault on Pago, Kuva Fortress, and the Systems blueprint are rewarded from Defection missions on Rotations B and C.
Additional main blueprints can be bought from Cephalon Simaris for 100,000100,000.

Notes
If Harrow wields his signatureKnell, 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.
Tips
Harrow can achieve the second highest total shield value out of all Warframes (behind Hildryn) at 4,110 by combining Redirection, Primed Vigor, Augur Accord, and his maximum Overshields. This number can potentially be higher with other buffs that increase shield capacity (such as Shield Charger and Sequence).
For Grinlok users, Harrow may offer quite a lot of synergy when considering critical chance Riven Mods and Deadly Sequence. Apart from being a decently accurate rifle, the mentioned mods synergize very well with Condemn, Penance, and 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 proc from the Sequence area of effect negates Ancient Healer auras allowing him to leech more health with Penance.
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 condemed 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.
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 associated named original Operator, Rell.
Also, he is the first original Warframe to have been active, since Orokin Empire, until the current timeline.
Since Rell is said to be Tenno outcast, 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 dropped from enemies.
Harrow swings his thurible to cast a spectral afterimage forward that travels along the ground for 15 / 16 / 18 / 20 meters. As the afterimage travels, it emits a growing wave of ghastly energy that completely immobilizes enemies in chains for 3 / 4 / 5 / 6 seconds. Each enemy enchained restores 100 / 110 / 125 / 150Shield points to Harrow which can accumulate Overshields.
Shield points are only granted on Condemn applying its chaining effect on unaffected enemies.
The spectral afterimage resembles Harrow's thurible being swung perpetually in motion. The thurible and its afterimage are affected by Harrow's chosen appearance and energy colors.
Affected enemies stagger backward to expose their head, then become locked in suspended animation.
Chained enemies glow in Harrow's chosen Warframe energy color, while covered in black chains that erupt from cracks formed on nearby surfaces.
Chained enemies will flinch in agony briefly when taking damage.
Casting Condemn is an One-Handed Action that allows firing weapons and player movement during the animation.
Cannot be cast if there is no valid surface 10 meters below Harrow.
Afterimage spawns from the ground at Harrow's current position and dissipates on direct impact with terrain obstructions.
Condemn affects mini-bosses such as Sprag and Ven'kra Tel, with diminishing returns.
If cast in midair, Harrow will instantly drop to the ground to perform this ability.
Tips & Tricks
Chain enemies in place for easy headshots, while replenishing your shields and building Overshields for increased durability.
Combine with Penance to stack extra duration and quickly refill your shields after casting.
Because Condemn's wave has travel time and shield points are gained at the moment when enemies are chained, you can preemptively cast Condemn toward enemies then immediately cast Penance, protecting your health pool from damage with newly earned shield points.
Condemn's wave grows in height and width as it travels, allowing it to chain airborne enemies such as Shield Ospreys when cast from a distance.
You can cast Condemn while aiming, firing, and reloading weapons, as well as when moving and maneuvering with parkour, without interruption.
Thurible and Condemn share the same Ability Range value at max rank. Since Thurible's aura is constantly visible while active, it can be used as a range indicator for how far Condemn's wave will travel from your position.
Shield points can be gained while you are invulnerable under Covenant's protection.
For new and experienced players, the ability will affect the Stalker for about a second or so. Crucial for newer players using Harrow to give them an advantage.
Harrow flagellates himself twice with his thurible, sacrificing all of his shields and Overshields to gain 20% / 25% / 30% / 35% ranged and melee weapons fire rate and 40% / 50% / 60% / 70% reload speed bonuses. While active, 5% of any damage dealt by Harrow to enemies converts into Health for Harrow and allies within his Affinity Range. Penance has a base duration of 4 seconds, plus extra duration of 1.25 / 1.33 / 1.43 / 1.54 seconds for every 100Shield and Overshields points drained.
Lifesteal on hit, weapon fire rate, and reload speed bonuses are affected by Ability Strength.
Base duration and bonus duration are affected by Ability Duration.
The amount of shields to be drained is determined on activation. Shield points from 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.
While active, stylized art appears beneath the aiming reticle; when a player is healed by Penance, colored text denoting the amount of health healed from damage dealt briefly replaces the art for several seconds. Both visuals are affected by Harrow's Warframe energy color.
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.
Can be recast while active to stack extra duration to the remaining time, up to a maximum total duration of 120 seconds.
Tips & Tricks
Mod for a higher shield pool to gain more extra duration for Penance by default.
Use 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.
Thurible Channel Harrow’s energy into the Thurible to generate a buff. Once finished, kill enemies to bestow nearby allies with bursts of energy. The more energy channeled the greater the reward for each kill. Headshots produce extra energy.
Once activated, Harrow chants in ritual to channel his Energy into the thurible at a rate of 10% of the base energy consumed per tick.
Ability Strength will increase the amount of energy gained per tick, while Ability Efficiency will reduce the amount of energy spent per tick. Ability Efficiency will not reduce the stored energy gained per tick.
Pressing the ability key again (default 3 ) stops the channeling, causing the thurible to generate an aura of incense around Harrow with a radius of 13 / 15 / 17 / 20 meters that lasts for 20 / 25 / 30 / 35 seconds. While active, each enemy killed by Harrow restores the charged amount of energy to Harrow and all allies inside his aura; if an enemy is killed by headshot, the amount of energy restored per player is multiplied by 4.
Energy per kill uses the following expression when accounting for Ability Strength and Ability Efficiency: Energy Per Kill = 1 Energy + [Number of Energy Drained × 10% ÷ (2 - Ability Efficiency)] × Ability Strength
With a maxed Intensify and maxed Streamline, draining 25 energy will yield 1 + [25 × 10% ÷ (2 - 130%)] × 130% = 5.643 energy per kill and ~5.6 × 4 = 22.4 energy per headshot kill.
Enemies killed anywhere by Harrow using ranged and melee weapons will reward energy; weapons with deployables such as the Zenistar are also eligible to reward energy from indirect kills.
Players using toggled abilities that drain energy per second can not gain energy from Thurible, similar to the mechanics of Energy Vampire.
While channeling energy into the thurible, the current amount of energy per kill is displayed to the right of the aiming reticle. The color of the text and stylized art are affected by Harrow's chosen Warframe energy color.
Thurible's buff icon is displayed beside the shield and health indicators on the HUD, with the amount of energy per kill indicated below the buff icon.
Upon killing an enemy via body-shot or headshot, a brief message displays above the ability icons indicating the total amount of energy restored per kill or per headshot kill.
Channeling Thurible is a two-handed upper body animation that disables weapon use, casting other abilities and Pickups collection, but allows player movement and parkour Maneuvers.
Can be recast while aura is active to channel energy. Channeling ends the previous instance of Thurible.
While active, Harrow is surrounded in a glow of energy and his incense aura is constantly visible to all players. Both visual effects are affected by his chosen Warframe energy color.
Warding Thurible is a Warframe Augment Mod for Harrow that reduces damage taken by allies within Thurible's range when channeled, and grants extra energy charge if those Allies are hit.
While channeling Thurible, you can still move and use parkour maneuvers such as roll, slide, bullet jump, aim glide, wall hop and wall cling to evade incoming enemy attacks.
Mod for Ability Strength and Ability Efficiency to increase the conversion rate per energy point spent. Natural Talent and Speed Drift greatly increase the speed at which each energy point is drained.
Flow (and Primed Flow) synergize with this ability. Higher maximum energy allows you to channel even stronger buffs, at the cost of longer channeling time.
Use Condemn to stop enemies in their tracks, allowing for easy headshot kills to maximize energy gain.
When under heavy fire, channel Thurible while under the protection of Covenant to guarantee your safety.
Melee channeled attacks benefit greatly from Thurible which can effectively refund the cost from kills.
Dark energy colors can greatly improve visibility for long range shooting due to Thurible's incense aura being constantly visible to you and your team.
However, lighter energy colors can allow teammates to spot the area of effect at a glance and rally to your position for energy restoration.
This is most likely a bug, but channeling the Thurible allows Harrow to use his melee with a Gravimag deployed Arch-Gun.
Covenant Protect nearby allies with an energy force that absorbs all damage and converts it to a Critical Chance bonus for all those under the Covenant. Headshots are amplified even further.
Misc:4.0x (headshot multiplier) 50 m (affinity range)
Info
Harrow breaks free of his shackles in a whirlwind of impenetrable energy, imbuing himself and allies inside his Affinity Range with complete invulnerability to damage and Status Effect immunity for 3 / 4 / 5 / 6 seconds. While invulnerable, any enemy damage prevented by all affected players during this time accumulates into a total pool.
Affinity Range is not affected by Ability Range but is affected by the Mending Unity passive in the Vazarin focus school, and can be temporarily increased with Fosfors.
Status effect immunity also protects against knockdown and stagger.
After the invulnerability phase, all affected players receive the Retaliation buff which provides an additive weapon critical chance bonus lasting for 6 / 8 / 10 / 12 seconds. Retaliation provides a 5% base critical chance, plus extra critical chance converted from total damage prevented at a rate of 1.50% per 100 damage points prevented. Additionally, the combined critical chance percentage is multiplied by 4 on headshot hits.
Base critical chance and extra critical chance percentages are affected by Ability Strength, while damage points prevented and headshot multiplier are not.
Retaliation's critical chance is capped at 50% on bodyshot hits and 200% on headshot hits.
The critical chance applied to the weapons appears to be a flat value.
Protection and Retaliation buffs affect both players and their Companions.
Covenant cannot be recast while its buffs are active.
Multiple Harrows can cast Covenant independently of other players' active invulnerability and critical chance buffs.
Casting animation of 3 seconds is affected by casting speed, from mods such as Natural Talent and Speed Drift. Casting Covenant stops Harrow's movement and actions.
During the invulnerability phase, the current total of damage prevented is displayed to the right of the aiming reticle, represented by a shield-like emblem.
After the invulnerability phase, the critical chance bonus and its headshot multiplied percentage are briefly displayed at the same position, represented by a bullet-like emblem.
An audible whispering sound plays when each buff's duration ends.
Covenant's buff icons for invulnerability and critical chance are displayed beside the shield and health indicators, with the critical chance bonus percentage located at the top-right of the icon and buff timers at the bottom.
Harrow and affected allies are visibly surrounded by a gust of energy while under Covenant's effects. This visual effect expands or contracts depending on the phases of the ability, and is affected by Harrow's chosen Warframe energy color.
Lasting Covenant is a Warframe Augment Mod for Harrow that increases Covenant's critical chance buff duration each time an enemy is killed with a headshot.
It synergizes well with abilities that buff critical damage, such as Electric Shield and Sonar.
Also pairs well with the Dual Toxocyst since they are at their optimal power when you are getting headshots.
Since the critical chance applied appears to be additive, this ability can turn a Nukor modded with Primed Target Cracker (and possibly other critical damage mods such as a Riven) into a viable critical secondary.
Casting this while attempting to revive a teammate makes for a reliable survival strategy, as the invulnerability phase will protect you from enemy fire.
If the mission has Environmental Hazards, like the toxic waste in the Grineer Shipyard tileset, you can use them to stack extra damage negation during the invulnerability phase.
Covenant synergizes well with a Kitgun equipped with Pax Seeker, with its projectiles gain benefits for critical chance to headshot from this ability.
However, headshot kills by Pax Seeker's projectiles won't trigger Lasting Covenant augmentation.

HARROW RELIQUARY COLLECTION
A shattered being bound by Void and will. Includes the Harrow Reliquary Skin, Renuntio Speargun Skin and Etheria Armor Set.
Fixes:
Fixed your Arch-Gun unequipping when casting Harrow’s Thurible ability twice.
Cephalon Simaris now sells Blueprints given during quests in his Offerings! This allows you to purchase these items in the event that you’ve accidentally sold them.
As per feedback, Harrow’s Systems Blueprint has been added as a Rare drop in Rotation B for Defection missions. This means you have 2 chances in the Endless loop to obtain Harrow, not just one at Rotation C. To maintain balance, a Bane of Corrupted Mod has moved to Rotation A.
Increased Harrow’s Energy gain from his Thurible ability (max ranked now gains 2x as much).
Increased Duration of Harrow’s Penance by around 20%.
Harrow will now detach from his Wall Latch when Channeling his Thurible to avoid awkward animations.
Reduced the amount of cloth movement on Harrow when viewing the Star Chart.
Fixed Harrow holding a shield (Silva & Aegis, etc) in an ancient style which history has long since forgotten (probably because shields are not useful if you hold them backwards).
