Well actually i played mundo late few times and i tryed many ways.2Warmongs does stack as blodthirsters cause it s just a passive.Okay heal might be useless unless i had spirit visage which boosts it and at 18 it s around 900heal form it it saved my *** few times.
Magic res i have alot and armor... okay little armor would be good But who hits 300 a sec-okay there are some champs /trynda/ but 5v5 fight they have no chance to pwn me with my u no even with ignite at me.okay 5v1 its .My point is when i have so high hp regen i don t need any of those.only one who can wn me is really fed olaf with bloodrazor.
Boots i played many games when we was hutning them i cannot get close enough to hit som1 with my infected cleaver because of that i said lvl2 boots no more.indeed when we against masive cc team mercurys but its rare.
Supernatural cow what you say have you tryed it already?

uggghhh... more warmog mundo builds. Look it up. It's been proven to be pointless on him. And wtf why two? This is just... hard to read. People seem to focus on the HP aspect of mundo and forget about MR and armor. Both of these will go a loooong way to keeping you alive late game, much more so then one, dare I say 2, warmog's. Force of Nature basically cancels the damage your abilities do.

DO you see your attack damage? It's sad. "But mundo is a tank so stfu."
SAD. JUST SAD.

fix this and i'll +1. For now -1. Plenty of better mundo guides on this site and others.

Well, okay, first off. Wow, that's a lot of health regen. I can see how this might work as a tank, and a very nasty tower killer, but there are a few things I don't quite understand. First off, why Heal for a summoner champion when you clearly don't need it? And also, why boots of tier 3, when a walking meatshield like that, isn't going to be needing to run around as much as someone who, say, dies a lot :P
Also, maybe it's just me being skeptical, but why 2 Warmog's? You know they don't stack, right? I would have thought a Guardian Angel would be better, considering it fits the theme of 'staying alive'.

But other than that, it looks like a fun build, and I think might be my next thing to try ^_^

EDIT: Oh and maybe just beef up the description a bit more, explain what you use and how you use it xD
