Nami vs Amumu Counter Pick
Matchup Summary
What the Data Means
Amumu takes the support clash, holding Nami to 44.4% across 252 games on patch 16.13.1. The reason is a damage-type trap rather than a stat gap. Nami deals magic damage, and Cursed Touch makes Amumu’s basic attacks curse his targets so that incoming magic damage carries bonus true damage with it. Everything Nami contributes feeds that passive: the burst on Aqua Prison, the bounce damage from Ebb and Flow, the on-hit magic granted by Tidecaller’s Blessing. With 560 base health and 29 armor she has nothing spare to absorb the follow-up.
Range should be the counterweight. Nami attacks from 550 units to Amumu’s 125, but Bandage Toss closes that instantly and stuns on arrival, and both champions move at 335, so no retreat is guaranteed once he commits. Despair then burns a percentage of maximum health each second while refreshing the curse, which is why longer fights favour a champion starting at 685 health and finishing at 2,283 over one at 560 and 2,056. Nami’s outs are positional rather than statistical: spend Aqua Prison after Bandage Toss has committed him instead of using it as poke, keep Surging Tides speed banked so the carry is never standing inside Curse of the Sad Mummy, and buy magic resist earlier than an enchanter usually would. Amumu rates 3 for difficulty to her 5. Kit detail: Amumu.
