LoL Kai'Sa players will find her to be a difficult champ to build out properly. You will notice that her build changes when she is fighting either well-rounded or highly focused team compositions, showing you shouldn't select the same Kai'Sa build every game of League of Legends
The most important items to use in your champ's build include: Tempestad de Luden, Muramana, and Sombrero mortal de Rabadon. Those who included these pieces in their setups had a much better winrate than those who utilized other item builds for Kai'Sa. Likewise, if you are fighting a mixed enemy team composition, you should strongly consider getting yourself the Precisión, and Inspiración runes. In recent matches, she won the largest number of her rounds when built with these runes.
