Not Updated For Current Season
My Katarina build contains lots of AP (ability power) and Mpen. (magic penetration)
Most champions will die quickly from Shunpo, and Death Lotus. Shunpo is great for dashing into battle, and finishing off with Death Lotus. Katarina is great for nuking,team battles,and versing somebody one on one when you are not with your team.
I go with a 9/0/21 build. You're gonna need the utility for Blink of an Eye,and cooldown reductions. The offense is used for a little bit of extra AP,Mpen,and for Exhaust.
Flash and Exhaust are great for chasing,and running in to save a teammate. You can also use Flash to escape, or exhaust to slow the opponent.
OTHER SPELLS YOU CAN USE INSTEAD
Ghost-Substituting Ghost for Flash wouldn't be a bad idea. Or you can replace Exhaust and use Ghost to catch up to an opponent,or just simply move faster.
Ignite-Instead of chasing,Ignite can just finish your enemy. Or used as a good damage spell.
Heal-The reason why Heal would be good,is because of turrets. Turrets always finish you off if you chased someone down in the middle of a turret. This is when Heal kicks in and saves you. But it's not the BEST spell.
THESE SPELLS ARE A NONO!
Clairvoyance-Why would you need vision for a couple of seconds? If you want vision, just buy a 90g sentry ward!
Clarity-Katarina doesn't use mana,pointless spell.
Rally-Extra damage isn't needed, Katarina's spells are what you use.
Teleport-Why bother using Teleport when there are better spells,and you can walk! Experience might be missed out on,but its not much.
Cleanse-You have Exhaust,Heal,Flash,or Ghost to back you up....Cleanse is useless.
Fortify-This spell is useful for the team,but using Fortify with a support character is better.
Revive-Good Hands takes care of this,and Revive just wastes a summoner spell slot. The cooldown is also wayyyy too long.
Smite-Not a jungler,and minions can be killed just using Bouncing Blade, or to harass.
For the Quintessences, there are three Greater Quintessences of Force. These runes are great for gaining extra AP.
On glyphs,the extra AP and Mpen help once again.
The seals contain pure AP for the true nuking power.
And finally,the marks.These marks contain Mpen and AP like the others.
These runes should help you do a lot more damage quicker and stronger.
At level 18,you should be strong enough to take out enemies quick,without dying as fast because of items.Katarina is known for the nuking and pumping out damage to take down many enemies as quick as possible.All of the AP should do most of the job.Fast damage is done and helps out the team.Katarina moves a decent speed,not too slow or fast.
That is my build for Katarina,vote for me!!
