Agree, The World is a OP move, maybe if someone gets a donut shape they can tell you what the move's weakness is.

Well the thing is, your grandpa from New York happens to know an ancient technique that uses both a meat product and a definition for the opposite of "off" for it's name that is specifically made for killing vampires.

However, using this jacket may grant you an evil spirit that protects you from any harm by delivering swift and powerfull punches while yelling a russian battlecry that goes "URA".

Given, the evil spirit also protects the vampire that has taken over the body of your great grandfather, meaning this is a pure test of skill and strength.
