Bloody0tree presents you with a solo/tank/jungle build that works well against anyone and you get to laugh as you regenerate to full health.

The runes give a good amount of health for your passive early game making you almost impossible to kill if you can play him right.

The items are pretty much the same from solo to jungle except you switch Murcery's treads for Boots of swiftness. Spirit Visage is really important, its boosts your passive (health regenerates for .3% of your maximum health. Spirit Visage makes you get more health back from your ult.

For Tank/Solo you want to get infected cleaver to level 5 as fast as possible because it gives the most damage and can make sure you get a kill from a gank. Of course always get your ult to level 3 as fast as possible 6/11/16. For jungling you want to burning agony to level 5 as fast as possible because it gives you the most damage output in order to wipe out the jungle and go help your team.

surprisingly, in my opinion, Dr. Mundo is one of the quickest jungler but he doesn't have much of a gank. I've had game where my opponent jungler is level 4 when i'm level 6 which gives a huge boost on my team.

Pros
-Hard to kill
-low cooldown on cleaver
-cleaver gives a huge slow
-burning agony gives a good method to farm
-really helpful ult with low cool down to keep you in the fight
-ult gives massive movement speed


Cons
-Not much of a damage output
-Takes time to be able to get good at cleaver
-people hide behind minions and so your cleaver can't hit

Jungling Dr. Mundo works pretty well. Burning agony gives a good damage output to wipe out your jungle. Turn on burning agony when you start attacking and make sure all of the neutral minions are in the range and focus the most powerful minion. Start at red and have another teammate guard blue until about 2 minutes.

For your gank to be effective through your cleaver to slow and turn on burning agony and masochism and follow your target and remember to throw the cleaver whenever you can.

For laning use Flash and Ignite for a good get away and ignite to give a good amount of damage.

Dr. Mundo is really effective in farming, turn on burning agony and masochism and clear out the minions in seconds.
