League of Legends Kassadin players will likely find him to be a complex champion to build out properly. You'll find that his build changes when he is up against either well-rounded or homogenous team compositions, meaning you should not follow the same Kassadin build every single game of League of Legends
The most important items to include in your champ's build include: Tempête de Luden, Étreinte du séraphin, and Coiffe de Rabadon. Those who included these items in their setups had a much higher winrate than those who went for other Kassadin builds. Moreover, if you are playing a well-mixed enemy team comp, you should strongly consider getting yourself the Domination, and Volonté runes. In recent matches, he won the greatest fraction of his games when using these runes.
