Amumu vs Senna Counter Pick

Senna’s 600 attack range is the longest of any opponent in this support pairing, a 475-unit gap over Amumu’s 125 — roughly the width of several minion waves. That range lets her build Absolution stacks from a safe distance and land Piercing Darkness pokes without ever entering Bandage Toss range, which is Amumu’s only reliable way to start a fight from outside melee distance.

Amumu wins only 41.7% of these matchups across 259 games on patch 16.13.1, a Hard-rated result and one of the larger samples in his support pool. Senna’s own HP total is comparatively low — 2,043 by level 18 — so a landed stun is genuinely dangerous to her if Amumu can close the distance. The issue is consistency: Last Embrace roots anything caught in its wave, giving Senna a way to punish an overextended engage before Amumu ever reaches attack range.

Senna’s mixed damage type also complicates itemization, since neither pure armor nor pure magic resist fully answers her kit. Her difficulty rating of 7 against Amumu’s 3 suggests the Senna player has more to manage mechanically — juggling Piercing Darkness’s dual heal-and-damage line with soul collection — but that complexity hasn’t stopped the matchup from favoring her at this sample size.
