League of Legends Senna players will find her to be a difficult champion to build out properly. You'll find that her build is modified when she is fighting either diversified or highly focused team compositions, indicating you shouldn't follow the same Senna build every game of League of Legends
The best items to incorporate into your champion's build include: Eclipse, Glaive Sombria, and Arco do Axioma. Players who included these items in their gear had a much better win rate than those who tried for other builds for Senna. Likewise, if you are battling a mixed enemy team comp, you should really consider grabbing Senna the Precisão, and Feitiçaria runes. In recent games, she won the largest fraction of her rounds when equipped with these runes.
