Destiny 2: Forsaken’s Last Wish raid finally released for all players at 1 p.m. EDT on Friday, Sept. 14, but the raid’s final boss remained undefeated until early the next morning, on Sept. 15. After nearly 19 hours of constant play, the players of Clan Redeem claimed victory over the Last Wish, and unleashed hell upon the Dreaming City location.

Bungie confirmed via Twitter that players Modern, Sweatcicle, Ehroar, Indica, FleshCrunch, and Gladd were the first to complete the Last Wish. The raid itself is extremely difficult, consisting of five different encounters and a far higher recommended power level than most players have access to.
