Katarina Build Guide by
Not Updated For Current Season
Bouncing blades is good for harassing enemies at the beginning of the game. As long as you can avoid getting hit from range, you can force them back to base for health, while you can take the turret. To avoid getting hit by ranged classes, hit a minion with bouncing blades near the champion. The blade should bounce and hit the champion. Since Katarina has no resources, use her abilities every time you get a chance (while avoiding being hit by champions).
"Kage's blade" gives a decent amount of money at the begining of the game, quickening the process of getting more items. It also serves as a great 5th skill once it is upgraded to "Deathfire grasp". This skill should be used when the opponent has got near full maximum health. "Rylai's Crystal Scepter" provides extra survivability, giving extra health, and a slow effect. It also gives you a decent amount of ability power. "Will of the ancients" provides more survival, and works especially good with Death Lotus, as it deals spell a constant mass of spell damage. Get "Rabadon's Deathcap" for bonus AP, then finish off by getting "Guardian Angel for the revival effect it gives.
