Quick question. I am Gming a game of dungeon world and a new player has come on board; he has chosen the paladin as his playbook/class. I'm confused as to how this class works-specifically that it says he can make an oath and gain an immunity to blades!!! How do you guys GM this, as it is obviously a very potent ability. Am I to take it that he cannot suffer any damage (in fiction consequences that would arise from being cut HP loss as well)? Am I missing something here?
I'm worried about balance and obviously confused....... help me out please!
