Taming the Storm
Equip your Arc subclass and new Exotic armor.
If you no longer have access to your Exotic, it can be reacquired from Collections.
Ikora believes you are ready for a final test of your Arc Light. Find the Devils' Lair in the Cosmodrome, and unleash the storm against their Prime Servitor.
"Take care not to overreach. Arc backlash is unpleasant, even at the best of times." —Ikora
