Dastardly Duos, a new group challenge where you fight two bosses at a time, also won’t release until June 3, despite being a major draw of the update.

Patch 11.1.5 includes Nightfall scenario, Dastardly Duos event, and Horrific Visions redux. The update may bring a 65% XP boost when combined with other buffs, likely arriving before May.
