Eris's Five-Sided Coin

Eris's Five-Sided Coin emerges in the chaotic finale of the dungeon's eighth floor as a cursed relic tied to the goddess of discord. Throughout the series it functions as both a powerful wildcard item and a narrative device that forces crawlers to confront unpredictable betrayals and alliances. Its five-sided nature symbolizes the ever-shifting loyalties and moral ambiguities that define the later books, culminating in high-stakes gambles during the Parade of Horribles.
