If you want to do a cave tame one of these 1: they can breath underwater good for an underwater cave

2: Small enough to fit in most small parts of the caves

3: A powerfull creature overall for deleting all of the cave creatures

Other: underwater spin attack stuns medium size creatures and dismounts othe players

Final note:thank you all who saw my tip and üq so more players can do the caves better and fight those bosses!
