Supposing, as a monk, I come into vast amounts of money and, heh, lack the wisdom to spend it otherwise....
If I have both a Body-Wrap of Mighty Fists and an Amulet of Mighty Fists, both enchanted to their maximum of +7 and +5 respectively, do the effects of both items, presuming they are otherwise compatible effects, stack together to give me an effective enhancement bonus of +12 to my unarmed attacks?
