Arc Charges

Arc Charges are the objective items used in Heist Battlegrounds to remove a Heist Commander's shield. Guardians collect them from enemies during the fight and deposit them at a central terminal. The Heist Commander raises its shield when its health drops to 50%, and depositing five Arc Charges causes the bunker's Defense Laser to destroy it. On the Moon the Heist Commander is Once-Phyris.
