What do i need to do here?
it's just william coins and i posted some info of it in the other thread
Making the weapon set permanent will require you to purchase an item in the mall(worth 35 coins each i think)
But for the armor set and the head and you'll be needing to grind willaim dungeon for the purple stone thingy and fulfilling the willaim space event quest for the injection thingy
editing this till i get more info
