I thought of using Amumu as an A.P. Champoion dps. I saw that alof of his abilities have bonus magic damage according to the current AP I have, this makes his abilities alot stronger. I will explaine the benefits furthermore.

Pure AP.

Went mana and speed to be able to support team fights.

Pure AP to increase all four abilities Ap dmg and percent of ap in dmg.

Balance Skill choice.

Because hes AP I choose mobile spells to chase kills and to save myself from being killed.

I think this build is interesting,fun, and exciting. Amumu as a Champion killer should be impressive and a sleeper. I challenge u to try it :)

Amumu is very fragile. Ghost and teleport will help in escape :)

Get the blue buff as much as u can, will help in team fights.

I would be the second hitter, comming in after the tank, not being the focus dmg. Comming in with all his abilities, he should drain the hp of all sourrounded champions. He can get multi kills like this, dont be suprised :)

STicky bandage then release the rest of the abilities, should do alot of dmg. Should be a nuclear strike!

I Would not be the inhitiator, i would bandage after your teamate takes the first strike, then beat them uP!
