Use Rek'Sai's mobility to your advantage; hop from lane to lane ganking the enemy and helping your allies. Use the time in between to jungle.
Tunnel is excellent to close the gap on enemies when chasing but if you overextend, it could put you in a bad position to get picked off.
LoL Rek'Sai players may find him to be a confusing character to build out properly. You will find that his build varies when he is playing against either diversified or highly focused team comps, indicating you should not choose the same Rek'Sai build every single round of League of Legends
The best items to use in your champ's build are: Prowler's Claw, Guardian Angel, and Maw of Malmortius. Those who included these pieces in their kits had a significantly better winrate than those who worked towards other builds for Rek'Sai. Moreover, if you are fighting a mixed enemy team composition, you should strongly consider getting Rek'Sai the Domination, and Inspiration runes. In recent games, he won the greatest number of his rounds when using these runes.
We established our Rek'Sai build guidance by examining 25,629 recently ranked League games with him selected.

With so many games in our dataset, we are quite confident in our provided builds.
