One last limbs question, now that we're on to claws:
The Claws evolution says you may only apply the claws evolution to legs once. Can a biped attack with claws on his feet if he only has two feet? I don't see anything prohibiting it, but I was wondering if I missed something.
Heck, since I've got your attention anyway, would the Reach evolution apply to all of one attack type (like claws) or just one of those claw attacks? EDIT: Nevermind. It clearly says one attack several times.
