I'd say you're overthinking it. Very much in the grand overthinking tradition of this forum, so applause, but...Arch Lich Burns wrote:But fists ARE a weapon and can be used as such. If intents matter then when punching someone they will be considered weapons and blind you.
It's called unarmed combat. Hands and feet are permanent parts of the body. They aren't separate devices. You can't set them aside and then pick them up again. So fists are not literally weapons -- only metaphorically so.
(I expect a prosthetic fist would count as a weapon, though.)
