LoL Jayce players may find him to be a confusing champion to build out properly. You'll see that his build changes when he is playing against either well-rounded or highly focused team comps, indicating you should not follow the same Jayce build every round of League of Legends
The best items to include in your champ's build are: Eclipse, Guardian Angel, and Serylda's Grudge. Those who included these pieces in their gear had a significantly better winrate than players who used other builds for Jayce. Likewise, if you are battling a mixed enemy team composition, you should strongly consider getting him the Inspiration, and Sorcery runes. In recent games, he won the greatest number of his rounds when equipped with these runes.
We came up with our Jayce build guidance by analyzing 16,390 recently ranked League rounds with him selected. We only recommend the top winrate Jayce builds that were built by ranked League players enough times for us to propose them. With so many matches in our dataset, we are quite confident in our suggested builds.
