League of Legends Senna players could find her to be a confusing champ to build out properly. You'll find that her build is modified when she is playing against either well-rounded or highly focused team compositions, meaning you should not take the same Senna build every game of League of Legends
The most important items to incorporate into your champion's build include: Eclipse, Umbral Glaive, and Axiom Arc. Those who added these pieces in their kits had a higher winrate than those who worked towards other Senna builds. Similarly, if you are trying to beat a well-mixed enemy team composition, you should strongly consider getting Senna the Precision, and Sorcery runes. In recent games, she won the largest number of her matches when built with these runes.
We established our Senna build guidance by examining 192,916 recently ranked League of Legends matches with her in them. We only recommend the highest winrate Senna builds that have been built by ranked players enough times for us to suggest them. With so many games in our dataset, we are confident in our suggested builds.
