Notes[]

  • Blood Rush multiplies critical chance based on the Melee Combo Counter tier increase.
    • Without a Combo Counter, Blood Rush provides no bonus to critical chance. At 2x, it increases critical chance by 0.40 × (2 - 1) = 40% and at 3x, it increases critical chance by 0.40 × (3 - 1) = 80%. At the standard max Combo Counter of 12x, it increases critical chance by +440% critical chance.
  • Blood Rush does work with quick melee strikes, as they do increase the Combo Counter, which is counted and maintained even if the weapon is not actively equipped.
  • Blood Rush cannot be equipped on EWDiwata.png Diwata, EWExaltedBlade.png Exalted Blade, EWValkyrTalons.png Valkyr Talons, EWIronStaff.png Iron Staff, Desert Wind.png Desert Wind, or ShadowClaws-Arsenal.webp Shadow Claws.
  • Pairs very well with Mod TT 20px.png Body Count, Mod TT 20px.png Drifting Contact or Mod TT 20px.png Gladiator Rush, which allow players to keep the Combo Counter up more consistently.
  • Since thrown attacks from Glaive weapons are affected by the Combo Counter, they will also receive any bonus from Blood Rush.

Calculation[]

The formula for calculating the increased critical chance reached by the mod is as follows:

Crit Chance = Weapon Crit Chance × [1 + Mod Crit Bonus + Blood Rush Bonus x (Combo Multi - 1)] + Static Crit Bonus

For example, a weapon with 20% base critical chance, modded with maxed Mod TT 20px.png True Steel (+120%) and Blood Rush, and with a Combo Multiplier of 4.0x would reach 20% × (1 + 120% + 40% × (4.0 - 1)) = 68% chance to crit.

The table below displays the critical chance that a melee weapon can achieve depending on its base critical chance and current combo multiplier.

Base Crit Chance Difference Per Multiplier Combo Multipliers (No Critical Chance Increase at 1x)
1x 2x 3x 4x 5x 6x 7x 8x 9x 10x 11x 12x

Crit Chance = Weapon Crit Chance × [1 + Mod Crit Bonus + Blood Rush Bonus x (Combo Multi - 1)] + Static Crit Bonus

  • Blood Rush Bonus: This is the bonus provided by Mod TT 20px.png Blood Rush based on its rank. Using mods from the Gladiator Set will increase this bonus further. For example, using two Gladiator Mods will effectively bring the total value up to 60%.
  • Combo Multi: This is the multiplier from your melee combo counter.
  • Mod Crit Bonus: This is the total of all other equipped mod bonuses added together (excluding Static and Blood Rush bonuses).
  • Static Crit Bonus: This is the bonus provided by mods like Mod TT 20px.png Cat's Eye (+60%) or special abilities like ArcaneAvenger64x.png Arcane Avenger (+45%). These bonuses stack additively with each other.

Trivia[]

  • Prior to Update 26.0 (2019-10-31), Blood Rush provided +165% critical chance per combo level. Critical chance was calculated according to the following equation:
Crit Chance = [Base Crit Chance × (1 + Mod Crit Chance) + Static Critical Chance Modifiers] × [1 + (Blood Rush Multiplier × Combo Multiplier)]

Patch History[]

Update 30.5 (2021-07-06)

Melee Mod Nerfs

Blood Rush’s maximum value is being lowered. This changes the achievability of consistent Red Crits from just one Mod (on most Melee weapons, some High-Critical exceptions), and now additional help will be needed via Mods, Arcanes, or Warframe abilities to achieve consistent Red Crits.

One Mod alone generally delivering the best tier of Criticals felt too powerful.

Blood Rush is changing from:
+60% Critical Chance stacks with Combo Multiplier

To
+40% Critical Chance stacks with Combo Multiplier

  • Fixed Blood Rush bonuses not resetting if you’re the Operator when the Combo expires.

  • Changed from multiplicative to additive with other mods. Now only multiplies base critical chance. Critical chance bonus went from 165% to 60%.
