LoL Rek'Sai players may find him to be a confusing character to build out properly. You'll find that his build is modified when he is up against either well-rounded or highly focused team compositions, showing you shouldn't choose the same Rek'Sai build every single round of League of Legends
The best items to include in your champ's build are: Estropieur, Gage de Sterak, and Manteau de la nuit. Players who added these pieces in their kits had a better winrate than those who went for other Rek'Sai builds. Likewise, if you are fighting a varied enemy team arrangement, you should really consider grabbing yourself the Domination, and Précision runes. In recent games, he won the largest number of his matches when built with these runes.
