[Inconspicuous Kitty]

I'll have to agree with Walrus and Snake on this - I feel as though the skill - and Black Knight - would lose a pretty iconic bit of their identity if the scaling was switched to Skill. I think that Fern's initial suggestion to allow it to activate Black Wind when it procs is fine - I think it'd actually be pretty neat if it procced it prior to recieving the damage, for the sweet damage reduction from Black Knight itself.
