Kayn vs Amumu Counter Pick
Matchup Summary
What the Data Means
Amumu deals magic damage and makes it worse for whoever receives it, since Cursed Touch marks enemies struck by his attacks so that incoming magic damage also inflicts bonus true damage. Kayn’s output is physical, so none of that amplification helps his opponent’s team, and 32 base magic resist is a reasonable starting point against the rest. Over 784 recorded games on patch 16.13.1 he takes 54.6%.
Tempo through the jungle favours Kayn. Shadow Step lets him walk through terrain, shortening every rotation between camps and every approach to an objective, and Reaping Slash attaches a dash to his damage. Amumu’s only gap-closer is Bandage Toss; miss that skillshot and he is a 125-range melee champion at 335 move speed chasing one who travels at 340.
Durability is closer than the class labels imply. Amumu opens with more health, 685 to 655, but ends on 2,283 against 2,406 and holds 101 armour at level 18 to Kayn’s 114.5. Tantrum permanently reduces the physical damage he takes, which is the one stat that genuinely blunts Kayn, while Curse of the Sad Mummy decides grouped fights as a multi-target stun that answers Umbral Trespass if saved for it. Despair drains a share of maximum health from everyone standing near him each second and refreshes the curse, so a long fight around an objective is his best case and the one Kayn should refuse. Difficulty ratings sit at 3 for Amumu and 8 for Kayn.
