Hello, summoner! It is guide for an top/adc/jungle urgot. Sorry about grammatical mistakes, my English is not perfect=)

pros:
High damage
Urgot is Tanky=)
Damage in %
control with E spell
Absolutly Insane R ability

cons:
Low mobility
short range
Big model

Passive

- shooting legs that deal extra damage with your aa,six legs -> six sectors around Urgot. Damage in % of max enemy hp. Move around enemy to deal damage.

Q

- good slow, but for a one second.Low damage,but it is not main ability!

W

- it is our main damage,our shield and our instrument to stack Fervor of Battle and Black Cleaver.Just two seconds and full stack of Black Cleaver and Fervor is ready.During this ability you can cast your other spells (q , e) and it will not be interrupted. You can interrupt it by pressing W again and run away from your enemies.
It is hit nearest enemy, if you want to hit enemy what you want you need before cast E/Q to hit it. Your combo q/e->w(move around to activate your passive)

E

- good control and dash.

R

- skillshot with that you destroy enemy which healths below 25% by pressing R again. Strategy in fights: you need to shoot enemy with 50% hp(priority:carry of problem brusier or problem tank) to slow him, damage him until his hp over 25%, press R to do Execution.

Instead of marks of Lethality you can take damage or armor penetration runes=)

I think this build of runes allow you to deal Insane Damage!
Fervor of Battle is must have because you can stack it very fast with your W!

Lifesteal items work with your W spell and Death's Dance work with your passive that allow you to steal from 200 to 400 health.
Black Cleaver is must have with its passive effect that allow you to reduce enemy's armor in 2 seconds by your W skill.
I recommend to buy items with hp boost because your W shield scailing from your bonus hp.

Red Buff -> Wolves -> Blue Buff -> gang.
Gang: q -> e -> w -> r -> r

Play safe.Your passive ability in early game have big cooldown. First of all you need gain level fast to deal insane damage. I recommend to buy corrupting potion to have sustain on lane and don t back to base.Don t fight with mobility champions like Riven because they can harass and fast jump out of your range. Remember you damage is your passive and W.
Win top combination:
Step one - wait until enemy try to harass you under your tower.
Step two - use your E on enemy
Step three - use your q. When enemy will have 50% hp use your R to slow him and hit him.
Step four - Press R again
----> Win
