If Stu did add Dragon Claws, Vengance would have to be moved, and the magic would you have to be changed, so you have to have a certain Magic Bonus to be able to cast Blitz's and Barrage's, In order to stop huge combo's being hit, because... Say you hit 20 with Barrage
Then Dragon Claws Spec
40-20-10-10
That's a KO, and it would most likely be entirely possible to hit 40 with Dragon Claws, as you can hit 40 with most wepons, as long as you have the Str Bonus.
