LoL Lulu players will likely find her to be a difficult character to build out properly. You'll notice that her build is modified when she is up against either well-rounded or highly focused team compositions, meaning you shouldn't choose the same Lulu build every single round of League of Legends
The most critical items to include in your champion's build are: Shurelya's Battlesong, Mikael's Blessing, and Ardent Censer. Those who included these items in their kits had a much better win rate than players who used other item builds for Lulu. Likewise, if you are battling a well-mixed enemy team comp, you should really consider grabbing yourself the Sorcery, and Resolve runes. In recent matches, she won the largest fraction of her matches when equipped with these runes.
We established our Lulu build guidance by analyzing 49,025 recently ranked LoL matches with her in them. We only advise the highest winrate Lulu builds that have been used by ranked League players enough times for us to propose them. With so many rounds in our dataset, we are confident in our recommended builds.
