You can take Ignite if you want lane the extra killing potential in lane, exhaust is pretty good on him too. Ghost is a must have, because ghost + Sadism = extreme engage and chase. There is not much to say, teleport is okay if you think of ganking bot lane.

As Mundo you're quite the farmer. In the early game, if you get zoned, just use q to farm. With the passive, hp will regen in no time. If you're shoved to the tower - do not fear! AD buff from the E will help killing the sorcerer creeps. Basic Mundo farming 101!

Mundo is an almonst unkillable tank, so act like one. Being in the middle of the fights, soaking adc, apc damage is your task, but if you dont have much tanky champs, stay not too far away from your squishies - they might need your help. Mundo synchronizes quite good with

Maplhite, Amumu and Kayle

.

If one likes to go jungling and wants to beat the **** out of the creeps, he should take Mundo. He has one of the fastest clear times of the game, his ganks are pretty good, counter jungling is an easy task for him. But be aware of early invades. Mundo is a mid/late game champ who is extremely hp hungry early. By clearing all the camps you WILL lose all of your bought pots. Do not take risk of staying in the jungle, go back. You dont really fall behind if your early is bad, but its nice to smack them early aswell.

This is a quick and simple guide for my main Dr. Mundo.He is a trully strong champ. Dont judge harshly, it is my first one and english is not my native language. If you'd like to contact me, I play on the always buggy EUW server and my nick is The PilotDown.
