BT/Stun/Bandage: Bandage Toss
Curse/Ult: Curse of the Sad Mummy

Amumu is a very amazing tank, but is unfortunately very uncommon and tends to be overlooked.


Items

Mercury Treads instead of Ninja Tabi
Situation: The enemy team has massive CC.

Force of Nature instead of Guardian Angel.
Situation: If your enemies suck and can't kill you.

Third Sunfire Cape
For the third sunfire cape, you need to (obviously) sell the Philosopher's Stone.


Skills

Bandage Toss
Amumu's skillshot stun. Important for chasing, support, and can (very rarely) be used as an over-the-wall get-away. Learn to aim this well.

Despair
Amumu's anti-HPstacker skill. This is amazing against everyone, but even more so against high-HP enemies. It is also very useful for Lizard, Golem, Baron, and Dragon.

Tantrum
Amumu's main skill. Passively makes him tougher, and actively great for farming and killing. Learning to hurt multiple minions evenly so you can get many kills at once with Tantrum is very helpful.

Curse of the Sad Mummy
The icing on the cake. Curse is probably the most valuable skill in LoL for team fights when used properly. If you're not initiating, which you should be, you can easily just Flash into the middle of all the enemy champions and pop Curse to snare all of them.


Play-style

Early
Conservative farming is what Amumu is all about at the beginning. Don't be afraid to use your Tantrum just to kill-shot 1 minion. You need all the cash you can manage.

Middle
Still should be farming, but you also need to be helping teammates out with being a gank initiator and/or lane helper.

Late
You should be a godly tank by now with your 2 or 3 sunfire capes, Veil, and GA/Force of Nature. You also should be destroying people while they (if they're good) focus on your carry(ies) and/or casters: stunning, Tantrum spamming, sunfire degen, Despair degen, Curse if there's 2 or more of them.


A very underused and overlooked champion, Amumu is an amazing tank.
