0 -1% +6% 6
1 -1% +7% 7
2 -1% +8% 8
3 -1% +10% 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.


  • The total bonus critical chance is 100% of EWIronStaff Iron Staff's base critical chance. Therefore when 100% is displayed on screen this augment is providing 25% additional critical chance.
    • This Augment only provides bonus critical chance to Iron Staff.
    • The additional critical chance stacks with critical chance mods.
      • For example, with a rank-3 True Steel equipped and Primal Fury's bonus at 50%, Iron Staff will have a critical chance of:
        Base Critical Chance × (1 + Critical Chance Mods + 1 × Primal Fury Percentage) =
        0.25 × (1 + 0.6 + 1 × 0.5) = 0.525
  • Critical chance per kill scales with Ability Strength while the decay rate is affected by Ability Duration.
    • The maximum bonus critical chance cap of 100% is not affected by mods.
    • For example, with a rank-3 Intensify 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-3 Continuity 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.
