We live in a world that is soaked with elements that transcend the power of earth's standards by quite a lot. There are things on Aeros that we (as humans) can't imagine or fathom within the confines of our organic cognition. Considering the fact that I've established the presence and dominance of third tier elements within our plane, I'm going to have to state that diamond dust won't be the most powerful weapon available. I understand your character lacks a kage, and thus, you deserve more power from external sources, but skill in swordplay is much more of a fair choice than swinging around god's dick. 

Keep it moderated, and you fine, tho. No worries. HUAAAAAAAAAAA!
