Arc Crystals

'''Arc Crystals''' are the crystals in the Arc Singers phase of Altars of Summoning. Ei Haaruz, Retainer of Savathûn, arrives with Lucent Conduits and a Lightbearer Hive that protect the crystals.

The fireteam first charges the crystals by using a melee attack on the primed Arc crystal, then melee attacks on the inert crystals to transfer its charge. Next, the team uses the Acolyte's Staff to invoke Hive magic, which shatters the Arc Crystals and removes Ei Haaruz's shield. Ei Haaruz can then be defeated.
