The Dual Destiny Quest is a limited-time quest in Destiny 2 that rewards players with the powerful exotic weapon, The Lament. To get the quest, players must first complete the “Beyond Light” campaign and reach the new soft cap of 1200 Power. Once this is done, players can speak to the NPC Shaw Han in the Cosmodrome to begin the quest.
The quest is relatively straightforward and can be completed in a few hours. However, players will need to be prepared to face some challenging enemies, including a final boss fight against Eramis, the Kell of Darkness.
