Mundo is one of the best tank/ junglers in the game this guide is mainly for a solo top but can be adjusted for a jungle. At the start of a game you will realise that mundo has problems with health sustain. If you have a Problem with that just simply buy health potions, i seem to be fine with just backing then teleporting back quickly

[*] Greater mark of resilience is mainly usefull early game enabling you to take hits and not that much damage so you can use your skills more often.
[*] Greater glyph of warding is the same use as the bonus armor enabling you to take hits from AP abilites.
[*] Greater seal of regeneration is for not losing too much health from your skills and lets you gain it back quickly.
[*] Greater quintessence of warding just adds on to the glyph and lets you take more hits from abilities and the reason I included 2 is to even out the armor and magic resist a little more
[*] Greater quintessance of resilience is the same as the mark to give you more lane sustainibility

Most guides will have defence masteries but with this guide i wanted mundo to not be comepletely useless when it comes to fights especally if you have a ****py team and have to carry they come in handy.

Most of the item build is based on items that include health, health regen and armor/ magic resist. My thought prosess behind this was that mundo already has alot of health regen at lvl 18 but i felt like it would be alot better and i will go through my thought prosess behind all of the final items
[*] Ninja Tabi: although tendancy would be nice he already has burning agony to reduce disable times and as a tank armor is important
[*]Raduin's Omen: Gives him all of the "Necessary" bonuses for mundo that i listed above a decent ammount of health armor and just a little health regen.
[*] Force of Nature: This item is one of the basics behind mundo builds and i just see it as a necessity
[*] Warmog's armor: this item also includes 2/3 bonuses massive health and decent health regen
[*] Maw of malmortius: This item is recently new and it goes back to the masteries where i didnt want mundo to be completely useless in team fights or if you need to carry
[*] Sunfire Cape: this item is pretty much the upgraded doran's shield with the bonus of dealing damage to near by enemies and adds to the effect of Burning agony

Teleport is a need for solo top if you want to sustain and hold the first turret. It can also be used late game to teleport to a nearby minion.
Flash is a great spell and can be used to hop over walls, escape incoming enemies or chase enemies
Also good for mundo are ghost,exaust or ignite
If you were to use this guide to jungle the 2 best spells would be ghost and smite

Well this concludes my first build please try it out before you rate or comment ive used this build for quite awhile and i am pleased with it and i am hoping you are too. Also be sure to send me some pics of your score(s) or even videos/clips of your game.
