and my build is ****ty compared to this....??

In response to all the questions.

1. Yes I know you only get the 25% buff once.

2. You wait if you know someone has a cc waiting for you, and yes that is kats biggest weakness.

and the last to are for those that don't know kats passive,

3. she gains 50g per kill/assist as a passive.

4. the best part of kat each champ kill/assist all ability cds are reduced by 15 secs, (plus when you have 800+ ap your shunpo hits for 1k a hit, and her ult does just under 400 per dagger in her ult.)

Ok so I did the math myself and the total stat score is 700 ap + 25% from the first ring which brings it to a grand total of 875. Unfortunetly this build is designed almost completely on her ult and her shunpo. The big draw back to this is that her ult only gains 30% of her ap as dmg. This leaves you spamming shunpo while your ult is down (giving you very little utility as a champion).

So all in all you would have to never get CCed and you would have to kill someone with each ult + gank with your shunpo to get your soulstealer to 20 stacks. the rest of your abilities dont play on your AP so thats all this champ would do. It is possible to do this... I have seen it played before, but it becomes very limited.

That's a lot of cash for one match. Is there a specific trick you use to pull that off?

Looks like you have 700ap with the 3 rings. I don't think you did your math correctly sir.

I have a question for you kat players in general, what in the heck do you do against CC heavy teams? Seems like every time I play Kat there's always at least one guy on the other team who is saving CC just to stop my ult... Is it just because I tend to get bad teams that aren't a threat without me or is there something else you all have in mind? Or is that just her weakness

Just a question for you..... are you counting the 25% AP bonus from EACH ring???
I only ask because these are unique qualities
