Really digging this so far- like the others, wanted to run a concept by you. 

I was thinking my character could be somewhat one-handed, his left hand has fallen victim to a bad burn, and can no longer feel. What I'm thinking is that there's a totem pattern (Probably some sort of lesser version of the hatchwork that makes heat, but nothing that could start a fire or anything) drawn on the palm that makes his left hand feel perpetually hot, and this is a very rudimentary way he uses to "feel", though it's really just changes in the heat that he's feeling (Sort of assuming that the heat generated by totems isn't "natural" heat and that's why he can feel it). Is that too weird? Is making him nearly one-handed too much of a hindrance?
