Jotaro Hat is a item ( I am not too sure about its spawntime and chances of this item
It appears to be a hat for Jotaro Kujo, one of the characters in Jojo's Bizarre Adventure. Just like its hat, it has some of Jotaro's hair on the hat, hat shaped like cap with a circle and a rectangle gold emblem on the front of the cap
What can it do?
It used to evolve Star Platinum ( Obtainable ) into Evil Spirit ( Unobtainable ), but now you can still evolve Star Platinum with Jotaro's Hat, but you will get Null, which is the same stand like standless / standless requiem
