Some clarification on the monk's unarmed damage is needed.
My monk is considering taking a few levels in sorcerer (dragon bloodline). This gives him the claws ability but that doesn't seem to give him any bonuses when he's doing his unarmed strikes.
That doesn't make much sense to me. I would think that a monk with claws would deal more damage.
Unarmed Strike (Monk or not) is not necessarily attacks with the hands, also kneeing, elbow, kicks, etc. On the fluff side - specific monk "attack forms" like open hand wouldn't really benefit from claws.
