League of Legends Gwen players will likely find her to be a complex champion to build out properly. You will notice that her build varies when she is playing against either generic or homogenous team comps, meaning you shouldn't choose the same Gwen build every game of League of Legends
The best items to incorporate into your champ's build are: Criafendas, Capuz da Morte de Rabadon, and Dente de Na'Shor. Those who added these pieces in their builds had a significantly better winrate than those who tried for other Gwen builds. Similarly, if you are facing a mixed enemy team composition, you should strongly consider getting yourself the Precisão, and Feitiçaria runes. In recent games, she won the largest fraction of her games when built with these runes.
We calculated our Gwen build suggestions by examining 56.234 recently ranked LoL matches with her in them. We only propose the best winrate Gwen builds that have been used by ranked players enough times for us to advise them. With so many games in our data, we are very confident in our suggested builds.
