Zac

Zac is an AP tank in the support, and on patch 16.17 they grade out as a solid mid-tier pick — a 50.0% win rate, 0.3% pick rate, 3,547 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 39.7% win rate across 121 games this patch. Pick the enemy team to adapt each item slot to the specific matchup.

The matchup to respect is Thresh, where Zac sits at just 43.5%, the lane swings the other way into Jhin (55.4%), and on the team side, Zac gains the most from a Darius (+4.5% pair win rate).
