50% from her ult, 50% from her Q. Her power chord has a 20% AP ratio which is doubled to 40% because of her Q. I DO count Lich bane because you'll be getting that as soon as you possibly can (and you wouldn't discount it for a Fizz or Twisted Fate for example) so that's an extra 75%, then the final 5% is from the spellsword mastery in the offence tree.
