Zac Support build for patch 16.11, generated from current-patch ranked Emerald+ games. Below: comp-aware build path, runes, top 10 bans for the matchup, and how Zac wins.
Zac is an AP tank in the support, and on patch 16.11 they grade out as a strong pick — a 53.1% win rate, 0.3% pick rate, 3,305 ranked games sampled. On the power curve, Zac is a scaling champion: comparatively weak early, but one of the strongest picks on the map once core items come online — so the plan is to survive the laning phase and take the game over late.
How Zac wins: grouped 5-v-5 teamfights, where Zac tips the fight, and landing engage and starting fights on Zac's terms. The kit grades 10/10 teamfighting, 9/10 engage, 7/10 roaming. Zac grades low on siege and split-push (3/10, 2/10), so don't take fights that turn on those dimensions.
The most-played core build is Celestial Opposition, Sunfire Aegis, Spirit Visage, which holds a 60.2% win rate across 98 games this patch. Pick the enemy team to adapt each item slot to the specific matchup.
The lane swings the other way into Caitlyn (54.1%), and on the team side, Zac gains the most from a Kayn (+9.2% pair win rate).
