League enemy

[darkzumi]

Need a clue or hint on how to beat the enemy accessed from the leagues' rooftop. My attacks normally deal thousands of damage but against this enemy only 5 with normal attacks. My animal kung-foolery only does like 15 damage... Seriously, WTH... Friend of mine used some other skills and some items (even some from the inner cyberspace) and nothing seems to help. Throw me a frickin' bone here!?

That item that doesn't work on any other foe in the game? That helps.
