Primal Rage is a Warframe Augment Mod for WukongIcon272 Wukong that increases the critical chance of PrimalFury130xDark Primal Fury with every kill, up to a maximum of 150%. The additional critical chance gradually falls off after 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 ReputationLargeBlack25,000 to purchase.


  • Primal Rage has a bonus cap of +150% critical chance. At full stacks EWIronStaff Iron Staff's critical chance will be 62.5%.
    • This Augment only provides bonus critical chance to Iron Staff.
    • The additional critical chance stacks with critical chance mods.
      • For example, with a rank-5 Mod TT 20pxTrue Steel equipped and Primal Fury's bonus at 50%, Iron Staff will have a critical chance of:
        Base Critical Chance × (1 + Critical Chance Mods + Primal Fury) =
        25 × (1 + 0.6 + 1.5) = 77.5
  • Critical chance per kill scales with 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 rank-5 Mod TT 20pxIntensify equipped, Iron Staff will gain:
      Base Critical Chance per Kill × (1 + Strength Mods) = 0.1 × (1 + 0.3) = 0.13 critical chance per kill.
    • With a rank-5 Mod TT 20pxContinuity equipped, the critical chance decay rate becomes:
      Base Decay Rate × (1 ÷ (1 + Duration Mods)) = 1 × (1 ÷ (1 + 0.3)) = 0.769/sec
  • 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 Wukong's shield and health indicators.

Patch HistoryEdit

Update 25.2
  • Increased cap from 100 to 150%, increased bonus per kill from 10% to 15%. Drain now scales with duration, so the higher Wukong’s duration, the slower it drains, and when Wukong gets a kill the drain stops for 5 seconds.

Hotfix 18.14.2
