Notes[]

  • When the buff times out, one stack is lost and the buff duration resets.
  • Ammo Maximum has no effect on battery weapons, such as Flux RifleCorpusLaserRifle.png Flux Rifle or Kitguns equipped with Pax ChargePaxCharge64x.png Pax Charge. The reload bonus however, will boost the recharge rate of ammo recovered.

Tips[]

  • Useful on weapons that can already kill groups of enemies quickly, such as most explosive weapons or weapons that chain between targets. Less useful on slow firing weapons that rely on status effects to kill their targets like single shot rifles.
