Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is -BY FAR- my way to go with amumu, in 3v3 or 5v5. This is a build for mid-late game but this doesnt mean that in early game you feed like noob. NO!! thats why you get those magic penetration runes.
Clarity: this is just for early game so you dont go to often to base, and in late is only for stay with dispair more time in a battle.
The second spell is as you like, i go with exhaust sometime or flash for ulti.
How you play it??
First, get boot so you can run faster when throwing tantrum and bandagge. When you have your first sunfire is time to get despair and here is when you start to own your foe's.
After the 3 sunfire cape is time to see if the other team is bad or doesnt have some hero to kill you after you ulti go and buy other sunfire or you can buy the Guardian Angel.
Then you buy the banshee so the first spell throw at you doesnt hurt to much in late game.
With this build and playing agressive in late have you have a WIN, ALWAYS
IF YOU READ THIS BUILD; PLEASE VOTE FOR IT OR LEAVE A COMMENT
