best ad kassa build so far i ve tried the rest but with this one i went from 2-2-11 to 17-9-20

ok got downvoted again just after i updated it.....

**** U gonna require a comment again :<

I did a really small update. Actually its only 1 build more. still that build is still aviable and fun to play...

unfortunately ad kassa doesnt fit into the current meta... maybe hed be a good jungler?

Cool, but unfortunately the W active got changed, so maybe hybrid Kassa is kind of more aviable now :<

well, It was interesting build at first glance; I'll give it that. My teammates had never played with an AD kass before and this was something new to them. I went 16-7-17. It was pretty fun all in all. The thing that you really need to have for this build is exhaust. you already have a slow, but that really helped me snag a lot of kills. It was definitely fun. Thanks for posting it.

I tried hybrid first time, but it's not fun as full ad. U only need your skills to disable the enemy.
but i already quit LoL so.. dunno

Isnt hybrid more viable than full ad? :/

I tried your build today. well, it was too squishy. I only had about 1,8k+ life not much >.<.
well, I'll try it again soon, that game was kind of strange..

hmm?

the build i gave you has 6 items, Black Cleaver, Stark's, YoYo's, IE, SotD, BG's. You could also put in LW or Atma's if you really wanted. Summoner spells are pretty optional. Doesn't really matter, except I would say probably Exhaust + Flash is the best for him. Either that or Exhaust + Ignite.

As for Item Order, I would go Stark's, Berserker Greaves, Black Cleaver, YoYo's/Atma's, IE, SoTD.

Good, I'll add it after I handed out my newspapers.
Btw, pls inform me if u find any grammar / spelling mistakes, I'm not native english. (Actually im vietnamese, but speakin german^^)

EDIT: Ah, I don't know which summoner skills u use. And what Itemorder, and there are only 4 Items so tell me 2 additional items, u think ad kassa could need :).

+1 if you give me credit :D

EDIT: Apparently also my 500th post :D

I'm okay with that, though I may eventually create my own Kassadin guide. Just give me full credit.

As to if it does more damage, it actually does because the build has armor REDUCTION, which CAN go past 0. Meaning if they have less armor then you have ArPen, your damage is MULTIPLIED. Which is why Stark's and Black Cleaver are so important on the build. You could probably use a Last Whisper too if you really wanted, but like you said it really only helps you against tanks. With the build you have about 180 ArPen anyways, which nobody except the tank will build that much and if they don't your damage is multiplied. By a lot. Your W alone penetrates half of the damage Thormail reduces, so I wouldn't say it's that big of a deal.

Anyways, the build I was using was this one:
