Dr. Mundo Build
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
To start off, go with Doran's Shield and a Health potion. Mundo's abilities cost health, and he doesn't have that much to start off compared to what you will get, so the health pot will help you keep alive for the laning phase.
Use Infected Cleaver to last hit on every minion you can, as well as harassing opponents in your lane. I normally don't leave the lane until I am level 7 or 8. Notice with Mundo's abilities costing hp, you probably won't have full hp. When I hit level 6, I just use his ulti to gain HP to stay in the lane for a bit longer. Once you have enough money, go buy Boots of Speed, and then buy Spirit Visage (1700ish gold). Spirit Visage is amazing.
Continue to last hit minions in your lane until you have enough to get Giant's Belt, or if you are feeling like you are all that, you can just save up to get a full Warmog's without going back and forth to buy separate items.
In the midst of this, if you see yourself getting a possible kill, go for it, just do not, I repeat, do NOT get greedy.
Usually once you get your Warmog's you will be out of the laning phase for the most part, and some fights will start to occur. Just keep trying to harass/kill enemies, and last hit minions when possible.
I usually bait my opponents into attacking me when I am at half health with ulti ready to be popped. With the amount of damage your cleaver does, you will probably kill them before they can kill you.
Once you have enough money, go finish off your boots, I like to go Beserker's Greaves, but it depends on your opponents. If they are high in fears/stuns/etc, go for Merc Treads. Fiddlesticks hates Merc Treads on Mundo, :).
Next item is Atma's Impaler, just an amazing item. The armor is a nice boost, you'll usually get around a 60-70% damage reduction with this build, depending on if you get Ninja Tabi or not.
If you are dying a lot, you probably aren't doing your job, but you can get Guardian Angel. If you aren't dying a lot, and if you got Beserker's Greaves earlier, go for Infinity Edge.
In late-late game, you can sell your Doran's Shield to build Phantom Dancer if you want to.
I usually go pretty good with this build. I went 11/0/13 with it on Rift a couple days ago. I am satisfied with it.
Go easy guys, this is my first build :). Advice would be appreciated.
