Not Updated For Current Season
Yes, Ability Power. I tried with dmg spec, but her ultimate is magic dmg and isn't so strong. Also, it's pretty long to get enough cash to buy a BF Sword. So is tried ability power and, shunpo is rly strong. I maximized all the magic penetration i could have and this wasn't bad. You should keep in mind that Katarina is a beginning and probably a mid game hero. If you are well feeded at the beginning, you have a chance to be good at the end... but most of the time, that's impossible. Also, there is too many other heros that are way better then Katarina. League of Legends should make something to increase the strengh of her. Any other way, she's useless.
So, for now, Ability Power Build is the best.
P.S. Don't know why, but i can't put my Masteries up :S
I can only say (24/0/6)
