Eris had fully exhausted her divine magic and body, causing her to fall into a deep sleep. For now, she was locked in her coffin beneath her heaven, resting to recover while her angels handled everything else.
From what Kali found out while inspecting her, it wasn't the fight itself or the portfolio use that had exhausted her this much, but it was that last move.
