League of Legends Yuumi players may find her to be a difficult champ to build out properly. You will find that her build changes when she is playing against either generic or specialized team compositions, indicating you should not select the same Yuumi build every game of League of Legends
The most essential items to use in your champ's build include: Moonstone Renewer, Mikael's Blessing, and Staff of Flowing Water. Players who added these items in their kits had a much better win rate than those who tried for other Yuumi builds. Likewise, if you are fighting a mixed enemy team composition, you should really consider grabbing yourself the Sorcery, and Precision runes. In recent games, she won the largest fraction of her games when using these runes.
We set our Yuumi build guidance by examining 110,956 recently ranked LoL matches with her in them. We only propose the highest winrate Yuumi builds that were used by ranked LoL players enough times for us to propose them. With so many rounds in our dataset, we are very confident in our recommended builds.
