LoL Illaoi players will likely find her to be a difficult champion to build out properly. You'll notice that her build varies when she is playing against either diversified or highly focused team compositions, demonstrating you should not take the same Illaoi build every single game of League of Legends
The most critical items to use in your champion's build are: Éviscérateur, Brise-coques, and Danse de la mort. Players who included these items in their builds had a higher win rate than players who utilized other item builds for Illaoi. Moreover, if you are facing a well-mixed enemy team composition, you should strongly consider getting yourself the Volonté, and Précision runes. In recent games, she won the largest number of her matches when using these runes.
