The Endless Dungeon begins on hard difficulty, and increases in difficulty after each boss battle. The Endless Dungeon works similar to the regular campaign, but there are several small differences:
- Players may only have three familiars at once
- The Cursed Sword of the Underworld, Paladin's Belt, Amulet of Light and Magic Elven Leaf do not spawn
- Buffs from passive items, such as Books of Magic, do not stack
- Vitality is capped at 200
- Spell damage is capped at 50
Players can view the deepest level they have reached in the endless dungeon in the Statistics menu in the camp.
