If you're in last place you might here the wispers of revenge and have a bat above you. Just go to the dark spot and surrender everything to become a darkling.
This requires two players. First have one become a darkling. Then, when you have enough dark points make the second player fight you. Strike and then have the other player counter. He should have killed you and now has the option to rob, give, prank, or forgive. Choose rob and take the sword! (this also works for the shield).
