AP Kai'Sa build with runes and items. AP Kai'Sa guide offers in-depth how-to play, skill order and tips. Play AP Kai'Sa build in League of Legends Patch 25.05!
Playing AP Kai'Sa build, your default rush is Luden's Companion. In cases, when an enemy team is full of tanks and HP stackers, go Liandry's Torment.
Adapt to an enemy team. Are they full of tanks, and they rush tons of Magic Resist? You rush Void Staff as #2 or #3 item to counter MR stacking. Their team has champs with lots of healing? Rush Oblivion Orb as #2 item (upgrade to Morellonomicon as 4th or 5th item).
Somebody is going after you each fight? Always getting ulted by enemy assassins? Rush Zhonya's Hourglass.
Champion
Reposition frequently when casting W (your E is handy for that). This way, you will get surprise hits on your opponents that do not expect your W to come from the other direction.
Try evolving W as fast as you can, you can do it by buying Lost Chapter + Blasting Wand + Amplifying Tome. Sometimes it is worth delaying Luden's Companion - when you back and don't have gold for it, but you have gold for Amplifying Tome.
Tips and Tricks
Champion
You can evolve your abilities while using portal (frost-gate)!
You don't need to have all evolutions.
For example when playing AD oriented builds, probably Icathian Rain (Q) and Supercharge (E) evolutions makes sense, but Void Seeker (W) not mandatory.
When playing AP oriented builds, Void Seeker (W) is must-have, but Icathian Rain (Q) or Supercharge (E) are pretty much optional.
Riot
Try to catch enemy carries alone to burst them with Icathian Rain.
Work with your teammates to set up your Ultimate and optimize damage with your passive.
Make sure to buy items that will evolve at least 1 or 2 of your spells.
