The '''Mysterious Cave''' is a dungeon that has a chance to spawn within the [[Dahlgur Oasis]] in [[Act II]]. Although the cave doesn't feature in any quests or events it's important in your quest to reach [[Whimsyshire]] as it's where the [[Liquid Rainbow]] is found needed to craft the [[Staff of Herding]]. The Liquid Rainbow will be found in a Mysterious Chest on level 1that randomly spawns in the cave.
