Once insomnia stops kicking me in the head so much that I can get back to posting, I think I have a way to interact with Myst.<br/><br/>As far as Superstrength, from my understanding, any melee weapon to which it works must have the Muscle quality.  Presumably it means that such weapons are able to withstand the force, and you know not to use your Superstrength with weapons without the quality because you'd break them.  Most weapons don't have it listed, but I could see it being part of the weapon just being properly forged and tempered to be able to be used by someone that powerful.
