Blue buff clear is Blue, Gromp, Wolves, Raptors, and then gank mid lane. After the gank go get scuttle crab, red, and then kruggs, and then if you have enough health, gank bot lane, or mid lane again.

Red buff clear is Red, Raptors, Wolves, Blue, Gromp, Gank mid or top lane, then scuttle. After, go down to kruggs, and then repeat the clear, because at that time raptors should be up again.

Fighting with amumu is very easy once you get items. Rylias makes it almost impossible for opponents to escape, and since you are a BURST MAGE, they wont have a chance too. Go in with your Q, with W activated, so rylias always procks. If they try to get away, Ult than E. This specific Amumu is not good in 1v1s, but in team fights, since he can stun the whole enemy team, and burst them down to half health so your team can clean them up.
