Overview

• Everdark Sovereign Libra went live on August 14 as the weekly Nightlord boss in Elden Ring: Nightreign, introducing seven named effects that overhaul the fight’s flow.
• Players and outlets documented mechanics such as replicant summons, friendly fire, invisibility, infinite flasks with level penalties, madness buildup, HP or FP reduction, and persistent Frenzy clouds.
• Much of the effect taxonomy comes from community reverse-engineering on Discord and Reddit, with several descriptions traced to a single user and awaiting broader validation.
• Tactical counters exploiting Libra’s Holy, Poison, Scarlet Rot and especially Madness weakness are circulating, including Frenzied Flame incantations and Bewitching Branches against summons.
• Debate is intensifying over the encounter’s balance as players test strategies and speculate whether FromSoftware will tune these disruptive mechanics in upcoming patches.
