I'm trying to look for skills that base more of their damage on weapon damage than off of max stamina. I think steel tornado does, but any other good skills that scale this way?
Well, all skills base their damage in the same stam-wd ratio 10.5 (most of them, rest are close to it) stam for 1WD, so even if they scale with WD more than other skills, they scale more with stamina too. Unless you mean something different.
//edit:
Like skills that have the biggest ratio... in that case steel tornado is even worse than most and bitting jabs are probably the best from stam.
