Harpies Trio

The three harpies can be found in the Wizards' Den orb room below the master of masters mini boss. Originally in this area there wasn't a wizards' den so the harpies aren't really fit thematically as of currently.

This fight encloses you in an arena with 3 harpies. one is normal and weak, the other is a flaming kind and the other can shoot a laser from its eyes.

Overall this fight is pretty easy and straightforward. Melee Immunity would make it a cake walk.

Touch of Spells can be used to easily kill this boss as it is not immune to their instant-kill effect.
