Hey guys, I'm Swainosaurus and im writing my first guide for mobafire. I'm however hoping that this will not be my last :). This guide will also be accompanied by a video version if you would prefer to watch that than read this.

Anyway Amumu is not very difficult to play once you get a feel for him. His Bandage Toss does feel awkward to use but his devastating effectiveness greatly outweighs this once you learn how to play him. His Ultimate Curse of the Sad Mummy can change around teamfights and even games if used effectively as it is extremely powerful.

So here is the video version of this guide, if anything is missed out in the video it is more likely somewhere in this guide :P

Amumu has many different strengths and weaknesses and can bring many different things to a team comp. For example, Amumu is a very good pick if your team lacks initiation and substantial bulk as Amumu will be able to provide both of these things.

Pros:
Game Changing Ultimate
High DPS whilst remaining tanky
Fast Clear time after a couple of levels
Great CC

Cons:
Easy to counter-jungle early
Heavy mana usage (preferable if you can have blue all game)
Bandage toss can be difficult to learn
High CD on ultimate.

Because of the new jungle changes it is difficult to precise figure out the most effective jungle routes at this particular time, however from current testing i have found that going:

Wolves
Blue
Wraiths
Wolves
Red

Is very effective on Amumu as it means he will have his smite up for both buffs and that he will be able to gank straight after red as he will be level 4 and have Bandage Toss.

This is quite a simple section.
Amumu takes what most other junglers take : Flash and Smite
As Amumu does not have any innate escape flash is needed to get out of bad situations and smite is necessary on all junglers for better buff control.

However, you can take ghost on Amumu for the chase potential but I think flash is a much better option.

Passive:
Cursed Touch

Amumu's autoattacks reduce the target's magic resistance by 15 / 20 / 25 for 3 seconds. This debuff does not stack but it refreshes with every autoattack.
This passive is very useful as it helps his W do much more % health damage as it shreds the opponents MR.

Q:
Bandage Toss
RANGE: 1100
COOLDOWN: 16 / 14 / 12 / 10 / 8
COST: 80 / 90 / 100 / 110 / 120 Mana

ACTIVE: Amumu tosses a sticky bandage in a straight line towards a target location. Amumu will pull himself to the enemy it contacts, dealing magic damage and stunning the target for 1 second.
MAGIC DAMAGE: 80 / 130 / 180 / 230 / 280 (+ 70% AP)
This is what you use to initiate ganks and team fights. A long range single-target stun with good ap ratio, overall very good skill.

W:
Despair
RANGE: 400
COOLDOWN: 1COST: 8 mana per second

TOGGLE: While toggled on, Amumu is surrounded by a small pool of damaging tears. Enemies in the area take magic damage each second equal to a base amount plus a percentage of their maximum health.
BASE MAGIC DAMAGE PER SECOND: 8 / 12 / 16 / 20 / 24
ADDITIONAL DAMAGE PER SECOND: 1.5 / 1.8 / 2.1 / 2.4 / 2.7% (+ 1% per 100 AP) of enemies' maximum health
Most Efficeint Damage/Mana skill Amumu has, always keep active during teamfights as the damage it does really starts to stack up, especially when combined with Amumu's other abilities.

E:
Tantrum
RANGE: 200
COOLDOWN: 10 / 9 / 8 / 7 / 6
COST: 35 Mana

PASSIVE: Amumu takes reduced physical damage from autoattacks and abilities.
PHYSICAL DAMAGE REDUCTION: 2 / 4 / 6 / 8 / 10
ACTIVE: Amumu releases his anger, dealing magic damage to surrounding enemies. Each autoattack that hits Amumu will reduce the cooldown on Tantrum's active by 0.5 seconds.
MAGIC DAMAGE: 75 / 100 / 125 / 150 / 175 (+ 50% AP)
Great for clearing the jungle as the cooldown is lowered every time Amumu is hit by the jungle creeps. Also does good AoE damage in teamfights.

R:
Curse of the Sad Mummy
RANGE: 550
COOLDOWN: 150 / 130 / 110
COST: 100 / 150 / 200 Mana

ACTIVE: Amumu entangles surrounding enemy units, dealing magic damage and rendering them unable to move and attack for 2 seconds.
MAGIC DAMAGE: 150 / 250 / 350 (+ 80% AP)
ABSOLUTELY BROKEN (if the CD wasnt so high). High Damage, AoE Stun. There is nothing more i can say apart from it is fantastic.

Overall, Amumu is very very rewarding champion to learn and to use. He is banned a lot in solo queue because of his ability to turn games on their head, but when he is available make sure to pick him up. When i produce new guides, make sure to check out www.youtube.com/user/Swainosaurus to see the videos :).
