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.
Okay I'm still not level 30 yet, I'm just a nice player. However, I discovered the fun of playing Amumu a couple months back when he was up for free. A couple of my friends have tried playing him and are having issues trying to be "as successful on Amumu" so I decided I'd toss up a build on here for them to work off of.
This is my first build on here and I'm still learning how to do this stuff so please be patient. I'll brush this build up more as I go along and make it more streamlined and easier to use.
If you have any suggestions/improvements for this build let me know.
Most people I see play Amumu as a jungler. That's all fine and good, I've done it a couple times myself, but often you will run into a Warwick or Nocturne that really want that jungle to themselves. Amumu is playable in lane you just gotta be clever about it and work with your team.
When you use this build, you have to play very aggressive! This build is for the lategame.
