Amumu

Amumu is an AP tank in the jungle, and on patch 16.11 they grade out as a solid mid-tier pick — a 52.0% win rate, 1.9% pick rate, 22,349 ranked games sampled. On the power curve, Amumu 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 Amumu wins: landing engage and starting fights on Amumu's terms, and grouped 5-v-5 teamfights, where Amumu tips the fight. The kit grades 10/10 engage, 10/10 teamfighting. Amumu 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 Liandry's Torment, Sunfire Aegis, Abyssal Mask, which holds a 56.7% win rate across 1,415 games this patch. The build above re-optimizes once you lock in the enemy composition.

The matchup to respect is Riven, where Amumu sits at just 43.5%, the lane swings the other way into Gwen (57.9%), and on the team side, Amumu gains the most from a Xerath (+7.4% pair win rate).
