Diablo 4 Hotfix 1 Tweaks Uber Mephisto Experience and Hoard Drops

Aureus Avatar by Aureus

Blizzard has rolled out Hotfix 1 (patch 3.1.0a) for Diablo 4, a small update that adjusts the experience rewards from Uber Mephisto. The hotfix reduces Uber Mephisto’s on-kill XP to bring it in line with other lair bosses, and adds experience orbs to his Hoard to compensate.

Notably, this hotfix does not address the Season 14 launch issues affecting Linux and Steam Deck players. Blizzard clarified that the emergency patch in the works will be separate from this one. The full notes are below.
