Vex Support, patch 16.11. Below you'll find Vex's build, runes, toughest counters, strongest duos, and win conditions, every number measured from current-patch Emerald+ ranked games.
Vex is an AP mage in the support, and on patch 16.11 they grade out as a solid mid-tier pick — a 51.6% win rate, 0.1% pick rate, 748 ranked games sampled. On the power curve, Vex spikes hardest in the mid game around the two-to-three-item mark — that is the window to force fights and objectives.
How Vex wins: grouped 5-v-5 teamfights, where Vex tips the fight, and sieging objectives and turrets with sustained pressure. The kit grades 8/10 teamfighting, 7/10 siege, 7/10 waveclear. Play around where Vex is thin, disengage and split-push (3/10, 2/10), and the enemy loses their angle.
The most-played core build is Zaz'Zak's Realmspike, Luden's Echo, Shadowflame, which holds a 54.8% win rate across 73 games this patch. Set the enemy team at the top of the page to see how the path shifts against that comp.
