LoL Gwen players will find her to be a challenging character to build out properly. You will notice that her build changes when she is up against either generic or specialized team compositions, showing you shouldn't choose the same Gwen build every single round of League of Legends
The most important items to incorporate into your champ's build include: Riftmaker, Rabadon's Deathcap, and Nashor's Tooth. Players who added these pieces in their builds had a greater winrate than those who went for other Gwen builds. Likewise, if you are facing a mixed enemy team arrangement, you should strongly consider getting yourself the Precision, and Sorcery runes. In recent games, she won the greatest fraction of her games when built with these runes.
We came up with our Gwen build suggestions by analyzing 56,234 recently ranked League matches with her selected. We only recommend the best winrate Gwen builds that were used by ranked LoL players enough times for us to suggest them. With so many matches in our dataset, we are confident in our suggested builds.
