Do you get a weapon to start in Glitter Hearts if you don't pick one as a power? Or can you do no damage on a Clash roll if your Physical is a 0?
You have to pick a weapon to have a weapon. If a person has a physical of 0, they do no damage unless they roll well on the clash roll. The GM can decide that they always do 1 damage if they wish, but I often say that there are so many other things to do, that it's ok for them not to do any damage unless they roll well.
