Amumu Jungle Build & Guide — Patch 26.18

Overview

Amumu is the simplest engage jungler in the game: walk into the fog of war (the unseen part of the map outside ally vision), throw Bandage Toss (Q), press Curse of the Sad Mummy (R), and let the team unload. His kit has one job — start the fight on your terms — and he does it from a longer range than almost any other engage thanks to the 1100-range pull. Cursed Touch (passive) then multiplies the damage of your AP teammates, turning their spells into bonus true damage on every Cursed target.

The trade-off: R sits on a 100-150s cooldown and Q is your only setup tool. Miss them and you spend 90 seconds being kited, so this guide is built around picking the right fight instead of forcing every gank. Game plan: clear, hit level 6, then translate every R into a kill or objective for the next 25-30 minutes.

Recommended Build

Starting items: Mosstomper Seedling (450g) + 1 Health Potion (50g). That is the full 500 gold you start with; the Refillable Potion is a first-back purchase, not a start. Mosstomper Seedling is one of the three jungle companions that replaced Emberknife and Hailblade back in patch 12.22. It speeds up your clear on neutral monsters (the jungle camps) and, once fully grown at 35 treats, grants a 200-360 shield (by level) that refreshes after every camp or 10 seconds out of combat, plus 50% reduced damage from non-epic monsters. The Refillable Potion you pick up on that first back is a healing item that refills for free at base, so you save gold on chip damage from the camps.

Core items (in order):

1. Liandry's Torment — your single most important item. The %max-HP burn passive doubles up with W, melting tanks who try to stand inside your aura. Buy this every game.
2. Mercury's Treads — default boots: they grant tenacity (a stat that shortens the duration of stuns and slows on you), which matters a lot for an engage champion who needs to keep walking after R lands. Swap to Plated Steelcaps if the enemy team has 3+ AD threats and no hard CC chain.
3. Riftmaker — Void Corruption gives 2% bonus damage for every second you stay in combat with enemy champions, up to 8%, and only at maximum strength does it start giving omnivamp. Void Infusion turns 2% of your bonus health into ability power, which is the part that pays a tank Amumu. Pairs perfectly with W's sustained aura.
4. Rabadon's Deathcap — late-game scaling multiplier. With Liandry's + Riftmaker already online, Deathcap pushes your W aura damage from "annoying" to "I cannot stand here for 2 seconds".

Situational items:

• Sunfire Aegis — vs melee bruiser-heavy teams (Sett, Darius, Olaf). The fire aura adds on top of W for double AOE damage and gives bonus armor. Patch 26.16 pushed it to 2800 gold and moved its power onto champions: 20 (+1.5% bonus health) per second, but only 150% against minions and 180% against monsters, so it is a fighting item now, not a clearing one.
• Abyssal Mask — when 3+ enemies deal magic damage. Its Unmake aura makes nearby enemy champions take 12% more magic damage; it does not reduce their magic resist, so it stacks cleanly with your own penetration and with Cursed Touch.
• Zhonya's Hourglass — vs burst comps that focus you the moment R lands (Zed, LeBlanc, Syndra). Stasis (a 2.5s window where you cannot be damaged or take actions) keeps you alive while your team finishes the fight.
• Banshee's Veil — vs long-duration magic CC chains (Ahri charm into all-in, Lissandra R, Morgana Q). The spellshield (a one-use barrier that blocks the next spell aimed at you) eats the engage.

Boots: Mercury's Treads is the default. Plated Steelcaps only into AD-heavy comps with no major CC chain.

Skill order: Max E first (clear speed and damage during sustained fights), Q second (gank threat and lower stun cooldown), W last. Take a point in R at levels 6, 11, 16.

Runes: Primary Resolve with Aftershock (gives you bonus armor and magic resist for 2.5 seconds the moment you hit a Q stun or R — the engage rune of the game), Font of Life (heals you and the lowest-health nearby ally whenever you impair an enemy's movement), Conditioning (extra resists after minute 12), Revitalize (boosts shields and heals on you). Secondary Sorcery with Manaflow Band (mana sustain so you can leave W toggled on through clears) and Transcendence (extra ability haste — a stat that lowers all your spell cooldowns).

Key matchups

• Lee Sin / Elise: Early-game junglers who invade your weak side. Track them with your Stealth Ward trinket (the free ward every champion carries, 2 charges, lasting 90 to 120 seconds by level; the paid pink ward is called a Control Ward) on your raptors and red buff (camps in your own jungle). Avoid 1v1 invades pre-3; do a full clear (kill every camp once), then head to Scuttle (the river crab that grants vision when killed) so they waste tempo looking for you.
• Master Yi / Karthus: Scaling junglers. Force fights and objectives (Drake on bot side, Rift Herald on top side, Baron later) before minute 18 — you scale fine, but they scale better. Every R you press should aim at their carry (the marksman or burst mage who deals most of the team's damage from the back), not their frontline tank, so the enemy team has nothing to peel for.
• Hecarim / Volibear: Mirror engage, faster clear. Don't try to outclear them; play around your laners and look to gank a lane with priority (priority = the lane that's pushing toward the enemy, so the laner can leave for a few seconds without losing minions) by minute 4.
• Maokai / Sejuani: Tank junglers with their own AOE engage. Whoever lands their R first wins the teamfight. Save Q for after they commit so your stun chains on top of their stun (the enemy stays locked for the full duration of both stuns added together).
• Kha'Zix / Rengar: Assassins who burst your back line. Body-block for your carries (literally stand between the assassin and your damage dealer to soak the hits) instead of standing in front of the enemy — your W aura plus E Tantrum punishes them for committing on a target you're standing next to.

Power spikes & win conditions

• Level 3: With E, W, and Q all unlocked, your first gank (a surprise visit from the jungler to a lane to score a kill) threat is real. Look at the lane with the lowest enemy HP and the strongest follow-up CC; one Q-W-AA-E rotation (AA = auto-attack) alongside an ally who is snowballing (snowballing = an early lead that keeps growing: kill → gold → item → more kills) is usually a kill.
• Level 6: First Curse of the Sad Mummy. This is the single biggest power swing in the game for Amumu. Find a fight within 30 seconds of hitting 6 — gank a lane, contest Scuttle, or set up the first Drake fight.
• Liandry's Torment completion (~ minute 12-14): Your W goes from poke to real threat. Fighting for Drake or Rift Herald with W ticking on a contest target wins the objective without ever pressing R.
• 3-item spike (~ minute 22-26): Liandry's + Riftmaker + Deathcap online. R cooldown is short enough that you can teamfight twice per Baron timer. Force every objective; this is your peak.

Common mistakes

• Throwing Q on cooldown without setup. A naked Q wastes your only engage tool. Hold Q until the enemy is already slowed, rooted (can't move), or hooked by an ally — e.g. Morgana Q hits → your Q on top is guaranteed. Q used as a scouting tool means you have nothing when the real fight comes.
• Pressing R as soon as you reach the fight. R is AOE centered on Amumu. If you press it 200 units short, you stun nobody and waste the 100-150s cooldown. Walk in until you are inside their back line, then R.
• Leaving W toggled on out of combat. Despair drains 8 mana per second while on, even with no enemies near. You will hit minute 8 with no mana for a Q stun on a clear gank. Toggle it off the second the fight or clear ends.
• Ignoring Tantrum's cooldown reset. E's passive cuts its own cooldown every time you take a basic attack. In a long fight against melee enemies you can press E every 1-2 seconds — stand in their attack range and keep spamming it.
• R-ing onto a tank instead of the carry. R is a teamfight ability. Yes the tank is closer, yes you'll land it on them — but your team wants the stun on the carry. Save Flash (the summoner spell almost every champion takes: a short teleport on a roughly five-minute cooldown) to flank around the fight (enter from a side or behind, not from the front) and engage on the back line, not on the front tank.

Advanced tip

Practice Flash then Q, in that order. Flash covers the last 400 units into their back line, and only then do you fire Q, so the 1100-range skillshot has almost no travel time to dodge. Doing it the other way round does nothing: Bandage Toss keeps flying towards the point it was aimed at even if Amumu moves after the cast.
