As far as I know, Whirlwind has UseCharacterStats "Yes" but does not feature increased damage. On the other hand, Crippling Blow has UseCharacterStats "No" but it shows increased damage. I'm not sure how to reconcile these details with what you describe in your post.

I would have to double check to see whether spells like Death Punch or Shocking Touch have this in their code, since their damage does scale with increased Int I believe.

EDIT: Looking at Lacerate/Precise Incision and Eye Gouge, they too seem to benefit from Primary Attributes up to a point of 50% multiplicative bonus damage, despite all of them having UseCharacterStats "No."
