My suggestion:
Charmed partyhat is the most special rare it says.
Still i never see it. My suggestion around it is:
Give it the stats of a neitiznot, and make it autokeep.
That'll truely make it a nice item to show off in multiple situations. It would also look nice, and itll draw eyes of new players maybe if they see the charmed phat in pk clips etc.
I chose to mimic the neitiznot to not make it OP, but still make it useable.
