Ornn Mid build for patch 16.17, generated from current-patch ranked Emerald+ games. Below: comp-aware build path, runes, top 10 bans for the matchup, and how Ornn wins.
Ornn is an engage tank in the mid, and on patch 16.17 they grade out as a situational pick — a 48.5% win rate, 0.1% pick rate, 844 ranked games sampled. On the power curve, Ornn 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 Ornn wins: landing engage and starting fights on Ornn's terms, and grouped 5-v-5 teamfights, where Ornn tips the fight. The kit grades 9/10 engage, 9/10 teamfighting. Ornn grades low on roaming and split-push (3/10, 3/10), so don't take fights that turn on those dimensions.
