League of Legends Rek'Sai players will find him to be a dynamic character to build out properly. You'll notice that his build varies when he is playing against either generic or specialized team compositions, demonstrating you shouldn't choose the same Rek'Sai build every round of League of Legends
The most important items to use in your champion's build are: Klaue des Meuchlers, Schutzengel, and Schlund von Malmortius. Those who included these items in their builds had a much higher winrate than those who tried for other builds for Rek'Sai. Similarly, if you are playing a varied enemy team arrangement, you should really consider grabbing him the Dominanz, and Inspiration runes. In recent games, he won the greatest fraction of his matches when equipped with these runes.
