League of Legends Thresh players will find him to be a difficult character to build out properly. You'll find that his build changes when he is fighting either well-rounded or homogenous team comps, showing you shouldn't select the same Thresh build every game of League of Legends
The most important items to include in your champ's build include: Linceul de la congruence, Convergence de Zeke, and Vœu du chevalier. Those who included these items in their setups had a much better winrate than those who used other Thresh builds. Similarly, if you are fighting a mixed enemy team composition, you should really consider grabbing yourself the Inspiration, and Volonté runes. In recent games, he won the largest percentage of his rounds when using these runes.
We set our Thresh build suggestions by examining 96 726 recently ranked League games with him in them. We only propose the highest winrate Thresh builds that have been built by ranked LoL players enough times for us to suggest them. With so many rounds in our dataset, we are confident in our recommended builds.
