Notes[]

  • Stacks additively with other base damage bonuses such as  Rubedo-Lined Barrel.
  • This mod has a buff icon which appears next to the player's health and shield display to indicate it is in effect.
  • As Archguns recharge instead of reload when wielded by Archwings in space combat or Necramechs, this mod has no effect in these scenarios.
