LoL Ekko players will likely find him to be a confusing champion to build out properly. You will notice that his build varies when he is up against either generic or homogenous team comps, indicating you shouldn't choose the same Ekko build every round of League of Legends
The most critical items to use in your champion's build include: Hextech-Raketengürtel, Rabadons Todeshaube, and Nashors Zahn. Players who added these pieces in their builds had a higher winrate than those who used other Ekko builds. Similarly, if you are fighting a mixed enemy team composition, you should really consider grabbing Ekko the Dominanz, and Präzision runes. In recent matches, he won the greatest number of his games when built with these runes.
