I was wondering about the no using weapons thing in the Animal Totem as well. I suspect it's about other weapons, but then you are still useless unless you rage. Maybe it could be something like no piercing weapons, or no bladed/metal weapons. That way could still you clubs, staff, that kind of thing.
And what about unarmed strike? I would assume that would still do lethal damage, or is Playtest saying nonlethal unless a monk?
