This is my personal build I am working on and trying, I don't play Amumu much but I checked previous builds and got a lot of kills and assists so I'm just mixing things up. When it's fully finished I'll update this.

Comment and rate if you like, I did however only want to use this for personal use but I think there may be rules against this :D but I will constantly be updating this everytime I use Amumu, until it's perfect.

Note: The few times I have played Amumu I have had over 20 assists and over 10 kills and under 5 deaths, I try to feed my team rather than feed myself so if you want a build for feeding yourself, this might not be the build for you.
