"Diablo 4 receives back-to-back updates with hotfixes and bug fixes"

Blizzard has released Diablo 4 hotfix 13, which fixes the Barbarian's Hammer of the Ancients bug and an issue with infinite monster spawning in Cellar Events. The previous hotfix 12 had inadvertently reduced the damage for Hammer of the Ancients, which was not intended, and has been reverted. A client-side patch with more class changes is expected soon.
