Amumu vs Locke Counter Pick

This jungle version of the Amumu-versus-Locke pairing has been recorded 583 times on patch 16.13.1 — an unusually large sample for a single jungle matchup — and the result leans clearly toward Amumu, who wins 57.3% of those games.

• Locke’s Ritual Nails needs to mark a target before the bonus damage on his attacks activates, a two-step process that’s harder to complete cleanly during a contested jungle skirmish than in an isolated duel.
• Amumu’s Curse of the Sad Mummy hits every nearby enemy at once, which matters more in objective fights than a single-target exchange.
• Both share the same 32 magic resist at base, so neither side gets a free damage-type advantage — Amumu’s magic damage and Locke’s physical damage both have to punch through comparable resistances.

Amumu’s difficulty rating of 3 against Locke’s 5 gives him a mechanical edge as well, since Locke’s kit — teleport-dash Ashen Pursuit, self-damaging Soul Ignition — asks for more precise sequencing than Amumu’s stun-and-drain approach. Both champions carry Mana as their resource, though Locke’s Silver Stake passive rewards him for finishing a target that’s already low, a pattern Amumu’s upfront burst tends to disrupt before it ever starts. Locke’s full kit is on his champion page.
