Reality Refuge is a high-difficulty challenge dungeon in NTE with Roguelike elements. Players explore randomly generated multi-layer anomaly spaces, encountering different enemies and random events on each floor. Key mechanics: 1) Requires entry tickets (from daily quests); 2) Deeper floors = harder difficulty but better rewards; 3) Character death in the dungeon loses some temporary buffs but doesn't affect normal progression; 4) Boss every 5 floors.
