  • The chance to trigger this skill is determined upon reloading the character's weapon. Skills, anointments, or weapon effects that regenerate ammo will not allow this skill to trigger multiple times on the same magazine, despite firing the "first" shot multiple times.
  • The bonus grenades fired are deducted from the character's ammo pool.
  • Grenades fired from Duct Tape Mod will deal self-damage to Zane.
