Wisps are a yellow glowing ball with the ability to quickly defend themselves from attackers. They work in mobs, in that if you attack one, you will find yourself being attacked by all Wisps who see you. Their attack strength is quite high, and their speed is reasonably fast. Non-aggressive, but will assist each other vigorously. Of the three glowing orb-like monsters (Wisps, Poltergeists, Spectres), the Wisp is the easiest to kill.
Wisps are found in the Graveyard, as well as the nearby swamp areas.
