This build right here, i approve! I just love it how i can accidently walk into a gank, activate ulti while retreating, wait for about 10 seconds and the hp is back to full! One thing i do though is that I get boots of swiftness just because i can and it gives a better chasing opportunity.

i really like your info on mundo. the guide isn't as pretty as others but you know your stuff. i scored a 12/2/18 first game and a 9/5/21 in the second game. not bad for a level 12 noob.

I really love playing mundo
But your Build.....Is a bit short for a nice Mundo
i would add some Mid-game items and some icons

I actually despise Force of Nature when i play mundo. It does nothing with your max hp which devalues your ultimate. The massive hp regeneration it provides is serious overkill when considering you already have Maximum Dosage, Warmog's Armor and Spirit Visage. The ONLY circumstance you should be rocking a FoN is if the opposing team is over stacked with AP champions. Thanks for the awesome question. I'll include it in the incoming Q&A section. I have a lot of work for this still.

don't make your guide in different colors. It annoys your eyes and makes it hard to read. Only change color of a couple of words you may want to change. Late game you may want to sell your dorans but you have not put anything to replace that on your cheat sheet. No mention of it in your item section either. You also don't say anything about Force of Nature which IMO is core Mundo.

Nice Mundoism n.n

Maybe add a video of Mundo going top as he pleases?
