Leona vs Yuumi Counter Pick
Matchup Summary
What the Data Means
Statistically this is one of the clearer support pairings: 2,448 games on patch 16.13.1 and a 56.5% win rate for Leona, graded Easy. The explanation begins with body size. Yuumi carries 500 base health and 1,673 at level 18, some 690 below Leona’s 2,363, alongside 25 armor and 25 magic resistance, so any moment spent detached is punishing.
Her escape is You and Me!, which makes her untargetable by everything except turrets while attached. That sounds like an answer but mostly relocates the problem, since the marksman absorbs what she avoids and Leona’s kit is designed to catch one target. Zenith Blade pulls the last enemy champion struck, Shield of Daybreak stuns on contact, and Sunlight makes each follow-up hit from an ally land harder. Yuumi’s contribution is Prowling Projectile, which gains damage and a stronger slow once it has travelled at least 1.35 seconds, plus Zoomies for shield, movement speed and attack speed. Neither addresses a 43 armor tank walking forward at 335 movement speed. Final Chapter is the exception, channelling five waves that damage enemies and heal allies while she keeps moving and reattaching, so a fight that runs long drifts back toward her. Difficulty ratings of 4 and 2 confirm this is not an execution-heavy matchup for either side; it is a question of whether the engage reaches the attached carry.
