LoL Kai'Sa players will find her to be a complex champion to build out properly. You'll notice that her build varies when she is playing against either generic or highly focused team comps, showing you should not take the same Kai'Sa build every game of League of Legends
The most essential items to use in your champion's build are: Hastklingen der Navori, Phantomtänzer, and Der Sammler. Those who added these items in their builds had a much higher winrate than players who tried for other item builds for Kai'Sa. Moreover, if you are battling a mixed enemy team arrangement, you should really consider grabbing Kai'Sa the Dominanz, and Präzision runes. In recent matches, she won the greatest fraction of her rounds when using these runes.
We came up with our Kai'Sa build recommendations by examining 325.819 recently ranked League games with her selected. We only recommend the top winrate Kai'Sa builds that were built by ranked players enough times for us to suggest them. With so many matches in our data, we are confident in our recommended builds.
