Not to ruin anyone's fun, but remind me again why this trick effects the monk's whole body? Unless you are looking at a magic item I've not heard of, the Necklace of Natural Weapons does not seem to imply that the enchantment bonuses effect the creature's entire body, and rather just whatever natural weapons it happens to be employing at the time. And yes, I understand one might make the argument that the monk's whole body is a weapon, but unfortunately this is realistically untrue (physiologically, if nothing else). So given this, can someone clarify exactly how this effect takes place?
