Covenant HarrowCovenant
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.
Strength:1.50% (critical per 100 damage)
Duration:3 / 4 / 5 / 6 s (invulnerability time)
6 / 8 / 10 / 12 s (critical chance time)
Misc:4.0x (headshot multiplier)
50 m (affinity range)

  • 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.

Tips & Tricks
  • 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.
