[@Half Pint] Oversized gauntlets/claws would just be Hand/Hand for the keyword, then you could bump up your RANGE based on how big/long you want them to be. 

Thrown weapons tend to be unpopular for espers due to the fact that letting go of your instrument for too long causes you to forcibly leave your esper form. There are going to be features that help combat that, but I figured it was best to make you aware of it. 

I do plan on expanding the list of weapon keywords, but players are encouraged to find a close approximation for more exotic selections. For an edged boomerang, Hatchet is a close match. It can be thrown and used in close quarters.
