A litte tip from me as I play Dr. Mundo alot, start with dorans, then start guilding Spirit, after you get your spirit, you should finnish your boots, and then get a Warmog or a Sunfire, then a Force of Nature. then an atmas. Attack speed on mundo is not really needed and you are much better at top then bot

Well I respect you opinion, I do have faith in my build. Late Game atma's may help especially when paired with a Zeke's maybe? Never tried it. We normally win first.

I have played docter mundo, and stacking warmogs is not the way. You can still get away from a 3vs1 with only one warmogs, but if you get atmas, your damage goes through the roof.

in a teamfight, your teammates will be dead before you can do significant amounts of damage with your aoe, because no ones going to focus some dr mundo with 3 warmogs...

I don't go AD basic attack. I get so tanky and in you face their is nothing you can do but turtle late game. My DPS's get fed and we win. 135 AOE damage/sec is actually significant when paired with the cleavers that deal 10% of your current health and slow you every 3.2 seconds. But I am really just a professional pain in the butt so that the DPS's can come in and clean house. I somehow still get kills with that common mistakely AOE damage of which you speak...

+1 and welcome to mobafire! :)
it is a common mistake, however to build mundo purely defensively. You need to but an Atma's Impaler if you stack warmogs. NEED. what does hp do for you if you dont do any damage? late game, Sunfire Aegis and Heart Zapper damage is so little there will barely be any impact

you also rely on your cleavers, so get more magic penetration.

another thing, you cleavers do 3% more damage from lvl 3 to 4, and 4 to 5. consider dropping a point in macochism.

consider taking a Zeal or attack speed rubes. with the semi-recent buff on his attack speed, it is worth it.

if I helped, check out my guides in return and +rep!

And yes, I go bot lane Mundo, where tanking is surpreme and despite the lategame runes, smart play and good itemization makes up for it. Trust me. I guess I should get a score screenshot huh...

Still a work in progress. Started it today and only worked on it for about an hour. I only published the guide so my friend could revise haha.

2 things to look at here.

30 defense is not a good idea. Bladed armor? Tough skin? even Vigor is kind of redundant on mundo.

I'd suggest 9/21/0 for mundo getting the magic pen in the offense tree. A bit of cdr and AD wouldn't hurt and you can improve your exhaust as well.

Secondly, get one point in masochism. 40 AD for a very small amount of hp is worthwhile. You sometimes will AA a player and if you do, it's nice to hit them for 30ish* more damage a swing.

I get that your runes are for late game when you start stacking mog's armors...but in the early game (when runes make the biggest difference) are they really worth it? How often do you get that far into your build? How often does that extra hp actually make a difference that late in the game?

Just a thought. Are you taking mundo bot lane? It kinda sounded like it in your blurb about gameplay. If he's being played as a support early on, you should start with wards.

Otherwise, consider dropping heal for smite and taking mundo for a spin in the jungle. He is quite strong there...

Needs a gameplay section, and you should have an actual conclusion, instead of just ending with a section about your Q.

I guess the build is optimal to a degree... Only because it's Mundo
