DON'T PLAY AGGRESSIVE UNTIL YOU ARE OVERPOWERED
How to Kill
1. killer instincts
2. bouncing blade
4. death lotis
You can ghost anytime between the steps.
What people don't understand about Kat is she is OP. The bouncing blades is your bread and butter. You can bug the **** out of enemy champions with it. Turn on killer instincts and shoot it at minions to lead it right to the bad guy. Killer instincts and bouncing blades combine reduces all healing regeneration for a short period of time so use it on enemy champions when the are using a health potion.
I know the description is brief but there is not much else to say. The item build and runes is pretty straight forward so why should I repeat it.
Good luck summoners. I hope this guide helped.
