To me Urgot was the best champs i ever see, after a lot of game with him on all lanes and all post i start to craft this guide to share my experience with Urgot in the jungle.
Why the jungle? Cause one day i think to one thing : Urgot jungle dream or reality? to know that i work on it during 1 month with friend to see all possibility of this champs, And he do an amazing job in the jungle !

Guide on works

Mark of Attack Damage : This Mark help to clean the jungle without problems. If you don't like this mark you can change it by mark of armor penetration.

Seal of Armor : You need some armor versus the jungle kreep, this 4 seal help you to clean jungle, in combo with Zaun-Touched Bolt Augmenter, you don't need more armor in early game to clean the jungle.

Seal of Scaling Health : the Urgot's way was to be tank but not in early. Scaling health was the way to the late game tank.

Glyph of Scaling Magic Resist : the classic glyph on a jungler, and i take it for the same reason of the Seal of Scaling Health if you prefer play on cooldown remplace this glyph by Glyph of Scaling Cooldown Reduction but care you will loose Magic resistance.

Quintessence of Attack Speed : Urgot got higth cooldown, to conter this problem in early game, attack speed will be the best, if you pick Glyph of Scaling Cooldown Reduction you can change Quintessence of Attack Speed by Quintessence of Attack Damage

loose to much potential on this masteries

Core Build

+ 4x : Classic start on jungler

+ + : this is you'r core build buy it in tis order, when you'r Tear of the Goddess was at 650-700 start to upgrade it to Manamune or befor if you'r feed.

Attack item

: to my part, the best attack item for urgot, mixed with [[Noxian corrosive charge its the better way to deal dammage and get cooldown.

[the bloodthirster size=40] : can remplace Black Cleaver but more defensive than it.

: not so bad, but i think not totaly usefull in jungle, test it, if you like it why not.

: Exelent item on urgot Sheen was totaly usefull on with Acid Hunter.

Defence AD Item

: one of best defensive item on with Randuin's Omen. Frozen Heart give you cooldown reduction and a lot of armor, on urgot that totaly amazing ! don't forget the 400 mana on you'r Manamune.

: the second best defensive item on , WIth Hyper-Kinetic Position Reverser you can go in the figth and use without problem Randuin's Omen. Personaly i prefer Frozen Heart.

: good item, that help you a lot with Hyper-Kinetic Position Reverser to don't die with a stupid move. Item +1 for beginer on

Defence AP Item

: best magic resistance on . Health, MR, and good passives !

: Only versus lot of AP on ennemys

Other

This other item was realy good, but depend of the situation.

: Good to catch higth move speed champion, like .

: Versus hard tank like .

: Need Health, buy it.

If you don't need shield :
If you need shield :

: Help to reduce damage from jungle kreep, during gank/teamfigth it the ADs champion.

: use it to deal damage on champion, mixed with Noxian Corrosive Charge this spell was auto and can it ennemis in bush too.

: you'r shield and you'r slow use it on rigth moment, or this spell will not totaly usefull !

: this is the best spell on , this spell apply all debuff, you need to never fail it !

: this spell can secure a kill during a gank : let the ennemis flash or run away, then use Hyper-Kinetic Position Reverser to swap position.
