League of Legends Kayn players will likely find him to be a challenging champion to build out properly. You'll see that his build varies when he is up against either well-rounded or highly focused team comps, indicating you should not take the same Kayn build every round of League of Legends
The most important items to include in your champion's build are: Dämmerungsklinge von Draktharr, Speer von Shojin, and Seryldas Bitterkeit. Those who added these items in their builds had a much higher winrate than players who worked towards other Kayn builds. Likewise, if you are battling a varied enemy team arrangement, you should strongly consider getting Kayn the Dominanz, and Zauberei runes. In recent games, he won the largest number of his games when equipped with these runes.
