Your Void weapons gain Volatile Rounds after you emerge from being invisible. When you are invisible and defeat a combatant while using a finisher, all of your weapons gain bonus damage; you and your nearby allies gain a reserve overshield and improved class ability regeneration. These reserve overshields can be deployed by using a class ability.
After being invisible, your Void weapons gain Volatile Rounds. Finishers while invisible grant bonus damage for all weapons and a reserve overshield for allies.
