Harrow

• 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 / 150 Shield points to Harrow which can accumulate Overshields.
  • Shields restored per target is affected by Ability Strength.
  • Wave distance and size are affected by Ability Range.
  • Duration is affected by Ability Duration.
  • Casting speed is affected by Natural Talent and Speed Drift.
  • 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.

• 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 / 1.05 / 1.11 / 1.25 seconds for every 100 Shield 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.
  • Affinity Range is not affected by Ability Range but is affected by the Mending Unity passive in the Vazarin focus school.
  • Casting animation of 2 seconds is affected by Natural Talent and Speed Drift.
  • 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.

• 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.
• Guardian, Protect, Brief Respite &  Arcane Barrier are useful for this ability as they are capable of restoring Harrow's shields.
• Cast 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

• Maximized Ability Duration increases base duration to 12.24 seconds and bonus duration to 3.83 seconds every 100 shield.
  • Has no negative effects on this ability.
• Maximized Ability Efficiency reduces cost to 12.5 energy.
  • Reduces base duration to 1.6 seconds and bonus duration to 0.5 seconds every 100 shield.
• Maximized Ability Range has no positive effects on this ability.
  • Reduces lifesteal on hit to 2%, fire speed bonus to 14%, and reload speed bonus to 28%
• Maximized Ability Strength increases lifesteal on hit to 20.6%, fire speed bonus to 144.2%, and reload speed bonus to 288.4%.
  • Without Energy Conversion and Growing Power, increases lifesteal on hit to 16.85%, fire speed bonus to 117.95%, and reload speed bonus to 235.9%.
  • Increases cost to 77.5 energy.
  • Reduces base duration to 2.9 seconds and bonus duration to 0.91 seconds every 100 shield.

• Once activated, Harrow chants in ritual to channel his Energy into the thurible at a rate of 5% 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.
  • The headshot multiplier is not increased by ability modifiers.
    • Energy per kill uses the following expression when accounting for Ability Strength and Ability Efficiency:
      Energy Per Kill = 1 Energy + [Number of Energy Drained × 5% ÷ (2 - Ability Efficiency)] × Ability Strength
    • With a maxed Intensify and maxed Streamline, draining 25 energy will yield 1 + [25 × 5% ÷ (2 - 130%)] × 130% = 3.321 energy per kill and ~3.3 × 4 = 13.3 energy per headshot kill.
  • Duration is affected by Ability Duration.
  • Aura radius is affected by Ability Range.
  • Channeling speed is affected by casting speed, from mods such as Natural Talent and Speed Drift.
  • 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.

Main article: Warding Thurible

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.
• Polearm-type melee weapons can consistently score headshots with quick melee attacks (default E ). This is a great alternative to gunplay when facing humanoid enemies such as the Grineer and Corpus.
• 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.

• 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.
  • Invulnerability duration is affected by Ability Duration.
  • 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.
  • Retaliation duration is affected by Ability Duration.
  • 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.
    • Critical chance seems to also be applied to melee weapons, weapon deployables (Zenistar disc, Orvius channel throw, etc.), and Exalted weapons (Excalibur's Exalted Blade, Ivara's Artemis Bow, etc.)
• 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.

Main article: Lasting Covenant

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.
