Hi this is my first Katarina build and first build evr Hope u all enjoy and use this guide and keep throwing those daggers in there face HAHA :D,and because kat is my main.

For runes i use Flat Ap tunes so i automatically start with 34 ap gives ap that haraasing power at the beginning of the game with another amp tome in total which gives you 55 ap to start.

For masterie[/color]s i got 9/21/0 because kat doesnt need utility and this guide is pure AP only

For items i start with amp tome and a health potion with gives me that large amount of ap when we start :D then i get a hextech revolver to a will of ancients because you are gonna be happy about that 25% spell vamp.then u should have about 3-0 and go on to the shoes which are either socerers or cd shoes, then we get the rabadon deathcap which should give u about 300 ap at 10minutes, this is when u will be getting those triple kills,then i get the mejais for stacks because starting from now this is when u will be getting those kills,then i get the rylais for the hp and slow, and i end it off with 1 more rabadon cap,and if u want by late game u could sell the spell camp for 1 more rabadon and u should be doing about 1k with shunpo and 250+ with each dagger from ur ult

The Skill sequence is Shunpo-Killer Instincts-Throwing Daggers-ULTIMATE,if they manage to get away use flash and ignite

For summoner spells i use flash and ignite this is what katarina only uses because flash is for the second get away skill use it right after ur shunpo

PROS
Fast get runaway with shunpo
ALL cds reset after u kill someone except ur ult takes about 3 kills
Insane dmg mid/late game good harass early game
CONS
Easily get killed when ue not by ur teamates
Squishy at early game
Only has 1 farming skills which is Q

If u want to go mid with Katarina always remember to use ur Q for Ez harassment,u will be doing this until laning is over

Thank you all for reading my first guild evr for katarina and LoL,Hope u all liked it, and hope you all have fun with the rest of ur days with Katarina :D
