League of Legends Vi players will likely find her to be a confusing champ to build out properly. You will notice that her build varies when she is up against either diversified or specialized team comps, showing you shouldn't select the same Vi build every game of League of Legends
The best items to include in your champion's build are: Trinity Force, Sterak's Gage, and Black Cleaver. Those who added these pieces in their setups had a greater winrate than players who tried for other builds for Vi. Similarly, if you are battling a well-mixed enemy team composition, you should really consider grabbing yourself the Precision, and Inspiration runes. In recent games, she won the largest percentage of her games when equipped with these runes.
We came up with our Vi build recommendations by examining 45,581 recently ranked League games with her in them. We only recommend the highest winrate Vi builds that were built by ranked players enough times for us to advise them. With so many games in our dataset, we are confident in our recommended builds.
