LoL Jax players will find him to be a dynamic champion to build out properly. You'll notice that his build changes when he is up against either well-rounded or homogenous team compositions, meaning you should not select the same Jax build every round of League of Legends
The most important items to include in your champion's build are: Göttlicher Entzweier, Steraks Pegel, and Zhonyas Stundenglas. Those who added these items in their builds had a higher winrate than players who used other builds for Jax. Likewise, if you are fighting a mixed enemy team arrangement, you should strongly consider getting him the Präzision, and Entschlossenheit runes. In recent matches, he won the largest fraction of his matches when built with these runes.
We set our Jax build guidance by examining 84.834 recently ranked LoL matches with him in them. We only advise the highest winrate Jax builds that have been used by ranked players enough times for us to propose them. With so many games in our dataset, we are confident in our recommended builds.
