I know this has been asked a million times, but I've had trouble navigating the other threads.
-What is the highest level 1 AP ratio skill in the game?
-What is the highest level 1 AP damage skill in the game? (Don't count singed, quick nukes only)
-Additionally, AD equivilant, what's the highest at level 1?
Edit: Thanks for the useful answers, I'm most curious about full flat AD/AP rune pages and what sort of damage is possible at level 1 from one skill. As one of you below said, Ashe has one of the highest at 140 ish damage from her Volley for AD. I would Wager Kha'zix's Q is stronger though with its 200% AD ratio
