LoL Orianna players could find her to be a challenging champ to build out properly. You'll find that her build varies when she is up against either generic or highly focused team compositions, indicating you shouldn't follow the same Orianna build every round of League of Legends
The most important items to use in your champion's build include: Affliction de Liandry, Coiffe de Rabadon, and Flamme-ombre. Those who included these items in their builds had a greater winrate than those who tried for other Orianna builds. Moreover, if you are fighting a varied enemy team composition, you should really consider grabbing her the Sorcellerie, and Inspiration runes. In recent games, she won the largest fraction of her games when equipped with these runes.
We calculated our Orianna build guidance by examining 65 751 recently ranked League games with her selected. We only propose the highest winrate Orianna builds that were built by ranked League players enough times for us to reccomend them. With so many rounds in our dataset, we are quite confident in our provided builds.
