LoL Orianna players will likely find her to be a difficult champ to build out properly. You will see that her build varies when she is fighting either well-rounded or specialized team comps, demonstrating you should not follow the same Orianna build every single game of League of Legends
The most important items to incorporate into your champ's build are: Ludens Sturm, Rabadons Todeshaube, and Schattenflamme. Those who added these items in their gear had a better win rate than those who tried for other builds for Orianna. Likewise, if you are facing a well-mixed enemy team arrangement, you should strongly consider getting yourself the Zauberei, and Inspiration runes. In recent games, she won the greatest number of her games when built with these runes.
