Kai'Sa Item Builds 1.3, How to Build Efficiently and Win
This is actually my third post on the topic. I've been iterating over and over again to find optimal ways to build Kai'sa and these are probably the best ones I've found to date.
Thing's to know going in.
- All build's assume 0 Rageblade stacks
- Kai'sa is auto attack based, where her passive applies AP to her auto's and has an AP based execute.
- She LOVES three stats, AP, AD, and AS. 4 items in the game provide two of these stats each and so as you can expect their great on her.
(Trinity force excluded do to her terrible base AD) - General utility finishers for builds include:

Now lets get started
Three Stat Rush Build

That is actually an extra dagger you won't use until your 4th item. Buy picking it up early, once you finish your AS component of Rageblade, you can evolve your E to have invisibility. Then after Rageblade, make sure to get the Bilgewater Cutlass first as it evolves your Q. When your finished with your build, you'll have 115 AD, 130 AP, and 97 AS (you get 1.8 AS per level, so assuming your level 3, You evolve your E).
The Goal is to get BoRK first since it sinergizes with your execute extremely well. You also want to evolve E first whenever possible since it give's the greatest safety and also most aggressive bonus out of them all. Ideally, you'd want to follow up with the cheapest rout to evolving your AD next since it give's wave clear and the most damage if you isolate someone. That is why this may be the optimal build as it gets you those two evolved before any other and also lets you evolve you W soon after the fact
Mid Lane Diver/Shredder

This build is designed to make you harder to kill, rip apart enemy stats, and have as many on-hit abilities as possible. This lets you Dive into enemy teams and make it so they take extra damage from your mixed damage auto's. It is FAR cheaper (like 2K gold cheaper at 4 items) than any other build in this guide, so helps you get your power earlier.
AP/AS Start Build
If you just want your AP Early, or planning on a Full AP build, this is a great starting point. It ramps your execute damage high and makes each auto hurt like a truck as Nashor's applies even MORE AP to each auto, and sinergizes with Rageblade. If you want to evolve all three abilities before 4 items (youd have to pick up BoRK's Cutlass component for that), you can get a
to get exactly 100 bonus AD instead of Gunblade
So these are the optimal builds for her. She loves Bonus stats so expensive items naturally fit her taste as they just have more of them. This was simply a guide to obtain them in optimal patterns. There are others like building a BoRK third in the AP/AS start build for an on-hit massacre. Her ratios are the source of all Kai'Sas power, so she can be very flexible depending on what you want to do. Go try her out! For easy builds follow these but don't be scared to experiment and find what works best against different champions! . . . . Hi, Analyst here. I love talking about these builds and what they do. If you have a build you love yourself, Talk about it below! If you could upvote so that more people can see it and I can share it with more people, that's just a nice bonus for me. In the mean time, looking forward to hearing from you :)

if you wanna get ballsy lol
(cuz her E makes her invisible, when empowered which is perfect for that burst)
