Mundo, as you know is known to do massive damage in the beginning and even better to tank later on. There comes a certain point though that he is better off just being a tank towards the end of the game. The question is, how do you keep this guy as a tank and continue to get more and more powerful? The answer is simple. He mainly relies on health and his ultimate throughout the game. Now Warmog's gives you a massive amount of health, as everyone knows. However people fail to remember that you can STACK Warmog's for a ridiculous amount of health. Now the more health that Mundo has, the better his health regeneration. His ultimate regenerates 50% of his health back to the way it was and Warmog's regenerates a percentage as well when the ultimate is not on. Just picture how difficult it would be to kill him when he already has over 6000 health, 50% health regeneration with his ult, being able to remove/reduce disables, and having Atma's Impaler to significantly increase his damage BECAUSE of his health. This is just sick. This is extremely fun to play as you don't have to worry about dying. Just don't forget to use your stupid ultimate. I recommended attack speed runes as with this build, you're not going to be getting attack speed at all. You need to mow people down with ease especially at the beginning. In the beginning get the attack speed runes and get masochism along with the boots and you can bush gank your enemies in the beginning without having to worry too much. MESSAGE TO NOOBS: Be aware of your health at all times as no character is invulnerable. If you're falling below 50% health before you have your ult in the beginning, I recommend going back to base for health just to be safe. It will just be a matter of time before you will reach this ridiculous build and won't worry about charging at the damage dealers/casters.
