Perhaps one of the oddest champions in the League of Legends is the yordle known as Amumu. His life before joining the League remains unknown... especially to Amumu. All he remembers is that he woke up alone inside a pyramid within the Shurima Desert. He was entwined in mummy wrappings and he could not feel his heart beat. Furthermore, he felt a deep sadness that he could not entirely explain; he knew he missed his parents, though he could not remember who they were. Dropping to his knees, Amumu wept into his bandages. No matter what he did, it seemed he could never stop his tears or sadness. Eventually he stood up, determined to wander the world to discover his past. Amumu traveled all across southern Valoran - a feat that is not easily dismissed.
While Amumu still hasn't learned much about his past, he has learned a great deal about who he has become. He is most assuredly undead, though he harbors none of the evil characteristics typical of undead beings. He also seems to keep trouble at arm's length; Amumu was able to traverse all of Southern Valoran without so much as a single bad thing happening to him. He was just sad, and the people and beings he encountered eventually shared his sadness. Ultimately, he made his way north across the Great Barrier to the Institute of War, the home of the League. Amumu's story was compelling to the summoners he met there, and they invited him to take part in a League Judgment. His success within the League as a champion has given Amumu something he desired: a home. With his present (un)life secured, he now hopes the friends he has made will help him discover his past.

Amumu, The Sad Mummy is a mobile jungler who utilizes his Bandage Toss (Q) and his ultimate, Curse of the Sad Mummy, to dive onto an entire enemy team and stun them to set up team fights. His Despair (W) combined with his Tantrum (E) allows him to clear jungle camps quickly and easily. He can either choose to go tanky/mage or just mage, depending on his team. I prefer Tanky/mage, he got a good utility and can be played in such many ways. The thing i love about him is that he always suprises the enemy, at start he can seem squishy and easy to kill, but in late game, he is a hardcore tanky/mage with high mobility.

(passive) (Cursed touch) is really good for making your Ap teammates deal more damage, its also good for your damage, so together with abyssal scepter it reduces the magic resist by 45 if your lvl 18. so its good to throw in some auto attacks.(W) (Despair)is the best option for jungling, after you got ur blue, it has a good damage output with nearly zero CD. After that, take (E) (tantrum) beacuse its Aoe damage and that is always good when clearing up the jungle. then at last you (Q) (Bandage toss). i alwways max this ability first, so i have good Ganks. then i max my (W) (Despair), beacuse of its NoN stop Aoe damage. its an option to max the (E) (Tantrum) second but thats only if you dont got the frozen heart. even if you dont i recommend to max your (W) Despair). Then of course Take a point in Your (R) Curse of the sad mummy whenever you can which is 6, 11 and 16.

Summoners insight is a clear choice for Amumu, boosting his flash, Summoners resolve is also a good choice, its giving him gold when he uses smite. Meditaion is giving him mana regen which is good. I'll take 3 points in expnded mind for the mana which is good when u dont have blue and havent got the frozen heart yet. Runic affinity boosts all buffs he gets, so 1 point in that, its making his blue be 20% longer and that helps him with jungling, so he can give oB to mid and take the eB himself. I take 3 points in mastermind for the cooldown reduction on your summoner spells. Then i take 4 points in Greed which gives my + 0,5/1/1,5/2 additional gold every 10 seconds, as a jungler i prefer this, beacuse extra gold is never wrong. And then, why not get + 25/50 additional starting gold every game, i take 2 points in wealth. Then i take 1 point in pickpocket and 3 points in intelligence, which gives me + 2/4/6% Cooldown reduction. I take 1 point in nimble. i will be able to clear up jungle camps faster beacuse i can get there faster, with 3% movement speed. I'll take 4 points in durability + 1,5/3/4,5/6 health every level, which gives a +108 health in level 18.
Then atlast i take 3 oints in hardiness which gives me +2/3,5/5 armor.
