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.
I most of the time start with a doran's schield because amumu is in the begin a bit weak
Then I take Mercury's Threads as boots for magic resist and reducing duration of slows and stuns
Is one off the things you realy need because its gives magic resist , Movement speed and it restores your health by 0.35% at each second
Sunfire Cape gives your health armor and deals 40 magic damage each second to nearby enemies
