I'm in a campaign, I'm playing a character with one leg. My DM said that I need a peg leg, but he said that if I have a good argument I don' t need one. My DM said that without a peg leg I'll have consequences, like difficult terrain. He is open to suggestions on how I can make it easier for my character so he won't get as many(or no) penalties. My DM and I both want this to happen but he just needs logical reasoning. Please Help.
