[@Mangrale] The only question I have with the techniques is the Mortal Salvo.  Mostly I just want to know to what extent he can control them.  Do they have to continually move and he can just bend their path, or is it more like Yamcha's Spirit Ball which he can control freely at will.  If they're like Tamcha's spirit ball in degrees of control I feel like 6 at a time would be too many, but if he is just bending their trejectories in flight that's completely fine, even if he does it in different directions.

Other than some clarification on that skill the rest seems fine.
