Astaroth, a familiar boss from previous Diablo 4 content, returns in Season 9 with a terrifying new twist. In the Escalation Nightmares, players will face an Exalted version of Astaroth that dramatically changes the battle dynamics.

During the fight, Astaroth sheds his mount and splits into two separate bosses, each with unique and deadly attack patterns. This split forces players to adapt quickly, learning new combos and positioning strategies to survive the encounter.

This revamped boss fight is designed to be the ultimate test of player skill and coordination, fitting the theme of Escalation Nightmares as a high-risk, high-reward challenge. It also adds fresh excitement to the endgame, encouraging players to master the mechanics and earn powerful rewards.
