Destiny 2’s final patch before Forsaken arrives is finally here. Patch 1.2.3 brings updates to exotic armor, strikes and Crucible. It also (finally) adds bounties and prestige-difficulty raid lairs into Destiny 2, giving longtime players new activities to tackle.

All of this comes just two weeks ahead of the Solstice of Heroes event, which will begin on July 31 and will give players a chance to earn new cosmetics and 400-power armor before Forsaken launches.
