What is the difference between Attack Damage and Bonus Attack Damage?
So, I'm approaching the higher levels and trying to improve my knowledge of the game as far as numberwise, but something that keeps tripping me up is that some scales are for AD and some are for Bonus AD. I'd like to know the difference to help with building for champs, like Draven, who have abilities that scale for Bonus AD. So, what is the difference and how is it applied?
