The jungle race — the windows in Jax's plan

Read from Jax's seat: the race windows this plan plays for against Amumu.

StageReadWhy
Level 1 ClearJax DominantLeap Strike trades onto anyone who steps up to contest your camp. Later in the game this bites, because a Bandage Toss stun into Tantrum spam wears you down inside his Despair aura. But before either of you has a second camp down none of it is online, so take the level-1 crossing and tax every camp Amumu concedes.
Level 2 SkirmishJax DominantCounter Strike dodges camp autos and stuns whoever commits into you, while Bandage Toss is their gank tool, not a duel-winner. Only one of those wins on the second camp, so press it: take the level-2 skirmish, then leave with the second buff and the tempo that comes with it.
Level 3 RouteJax DominantThe Empower-Leap burst plus E stun favors you into any auto-attacker. Despair tank stats clear fine, but champion duels are losers, and as the first scuttle timer lands that is not an answer. Take the level-3 river fight and make Amumu path away from the camps you want.
Levels 4-5 MacroJax Dominant — Keep FightingNothing about 4-5 helps Amumu here: levels 4-5 are pure gank-hunting for him — a Bandage Toss into any lane with follow-up beats a full clear, while you can take any duel you can reach. Invade on the clear-timer, not on a whim.
Level 6 BreakpointGrandmaster-at-Arms FavouredGrandmaster-at-Arms resists plus Counter Strike make the extended duel unloseable. Amumu's six is not empty — a Bandage Toss into the AoE Curse locks you down for the full follow-up. Take the duel from even health rather than from behind, and the engage is two dodgeable skill-shots — respect the angle, not the mummy.
First Item SpikeSundered Sky SpikeYour first fight item plus R turns you into the best one-item duelist in most lobbies — Amumu included. Invade openly, take every camp standoff, and dive chipped laners with E opening the tower's aggro window. Your clear also accelerates enough to full-clear and contest every spawning objective. Amumu's first completed item makes Despair and Tantrum clear at real speed and turns his engage into a genuine team-fight threat.
2+ Items ScalingJax Favoured — Wins LateThe late game is yours. Remember what Amumu still is at full build — he is a Curse-and-run engager whose value is the ultimate, not the duel — and take the fights that do not let it matter.

How to beat Amumu as Jax: the first clear and pathing

Start the buff that paths you through raptors early — E's AoE stun makes the chaos camps trivial. Note Amumu's start side and plan a same-side full clear; you want farm, not level-2 coin flips. Amumu opens on a buff and clears steadily off Despair and Tantrum, so he is rarely far from his own camps before three.
