Elden Ring Nightreign Adds Harmonia Boss Fight from The Forsaken Hollows DLC

DLC Required

This particular fight comes with a catch - you'll need The Forsaken Hollows DLC installed and must have already defeated Harmonia in the standard game before the enhanced version becomes available.

Everdark Sovereign System

The Everdark Sovereign rotation features enhanced versions of Nightreign's bosses:

• Tricephalos
• Gaping Jaw
• Sentient Pest
• Augur
• Equilibrious Beast
• Darkdrift Knight
• Fissure in the Fog
• Harmonia, Weapon-Bequeathed (DLC)

Three bosses appear on a weekly rotation, and defeating them earns Sovereign Sigils that can be traded at the Roundtable for special relics.

Online Required

As with all Everdark Sovereign content, an active internet connection is required to participate in these enhanced boss encounters.
