Primal Rage is a Warframe Augment Mod for WukongIcon272.png Wukong that increases the critical chance of PrimalFury130xDark.png Primal Fury with every kill, up to a maximum of 150%. The additional critical chance gradually falls off after WukongIcon272.png Wukong stops killing for 5 seconds.


Rank Decay per second Critical chance per kill Cost
0 -1% +8% 6
1 -1% +10% 7
2 -1% +12% 8
3 -1% +15% 9


  • This mod can be acquired by attaining the rank of Maxim under the Arbiters of Hexis, or the rank of Flawless under New Loka, and spending ReputationBlackx64.png 25,000 to purchase.


  • Primal Rage has a bonus cap of +150% critical chance. At full stacks IronStaff.png Iron Staff's critical chance will be 62.5%.
    • This Augment only provides bonus critical chance to Iron Staff.
    • The critical chance bonus is additive with critical chance mods.
      • For example, with a max-ranked Mod TT 20px.png True Steel and Mod TT 20px.png Primal Rage's bonus at 150%, Iron Staff will have:
        Base Critical Chance × (1 + Critical Chance Mods + Primal Fury) =
        25% × (1 + 1.2 + 1.5) = 92.5% critical chance
  • Critical chance per kill is affected by Ability Strength while the decay rate is affected by Ability Duration.
    • The maximum bonus critical chance cap of 150% is not affected by mods.
    • For example, with a max-ranked Mod TT 20px.png Intensify and Mod TT 20px.png Primal Rage, Iron Staff will gain:
      Base Critical Chance per Kill × (1 + Strength Mods) = 15% × (1 + 0.3) = 19.5% critical chance per kill
    • With a max-ranked Mod TT 20px.png Continuity, the critical chance decay rate becomes:
      Base Decay Rate ÷ (1 + Duration Mods) = 1% ÷ (1 + 0.3) = 0.7692%/sec
  • WukongIcon272.png Wukong retains Primal Rage's effects as long as Primal Fury remains active, and the bonus will reset if Primal Fury is deactivated by any means.
  • Primal Rage's current percentages are displayed beside WukongIcon272.png Wukong's shield and health indicators.

Patch History[]

Update 25.2 (2019-06-19)

  • Increased cap from 100 to 150%, increased bonus per kill from 10% to 15%. Drain now scales with duration, so the higher WukongIcon272.png Wukong’s duration, the slower it drains, and when WukongIcon272.png Wukong gets a kill the drain stops for 5 seconds.
