Hey, so this is how it is. I'm not about to put mad time into the description of why I chose ****. This is after like a billion games played with Urgot. I'll be making my points with bullets so it's easier to read quickly. If I may suggest, read the E N D G A M E Urgot guide to learn how to be successful with him, but the build is COMPLETE trash against 50% of the teams you'll play in ranked. This is THE URGOT BUILD FOR KIDS WHO DON'T SUCK. Getatit.

PROS:
- Urgot has simply the best starting damage of any champion excluding Pantheon and Ezreal.
- Can easily carry teams to victory without being **** squishy.
- Can function as a Support/Dps if need be, (but need should not be).
- Great team player, I'd say up there with Vladimir and Trundle.
- Mobile, long range, high damage, survivable. He even comes with a shield.

CONS:
- You don't start with Crabgot skin. :P
- May be difficult to play without experience.
- Sometimes the Acid Hunter can be a pain in the *** to land in teamfights
- More Micro-work than perhaps 80% of other champions.

His skills are where his REAL damage lie. For instance; You build standard carry (damage/AS/crit), and auto attack. This works, and you do plenty of damage, but other ranged AD carries have at least 50-100+ range over your auto attack. Since you didn't build how I reccomend, you'll be squishy and take high damage. Urgot's passive however would help.

-Zuan Touched Bolt Augmenter:
This is Urgot's Passive, Urgot's attacks reduce his targets' damage by 15% for 2.5 seconds. This applies for BOTH auto attacks and his Acid Hunter. Therefore, the stacked autoattack build of a carry isn't necessary to ruin someone's damage and still do a large amount yourself.

-Acid Hunter:
This is Urgot's bread and butter. Urgot fires an Acid Hunter missile that collides with the first enemy it hits, slowing the target if he has his Terror Capacitor up. Acid Hunter missile-locks on enemies affected by Noxian Corrosive Charge. Max this first. Passive applies.

-Terror Capacitor:
Urgot charges up his capacitor to gain a shield. While the shield is active, Urgot gains slowing attacks. This stacks with AP, so the 30 points from the Trinity Force helps a bit.

-Noxian Corrosive Charge:
Urgot launches a corrosive charge that damages enemies in an area and reduces their armor. You MUST level this quickly after you get Acid Hunter to level 4, then max this out after Acid Hunter hits level 5. The armor reduction + your passive will ruin anyone's game. You should hit multiple targets, but if that isn't possible, then hit the carry and focus them down.

-Hyper=Kinetic Position Reverser (Ultimate):
Urgot charges up his Hyper-Kinetic Position Reverser, swapping positions with the target. His target is suppressed for the duration of the channel. He gains increased armor and magic resistance after the swap. Catch a lone straggler, initiate against a smaller enemy force, save your teammate, stun an Ult'ing Kat, or whatever. This is one of the better Ultimates in the game, despite what your level 15 friend says. USE OFTEN AND WITH CAUTION. It will make or break you.

You wont need the menial defensive bonus of the Defense trees, you have runes for that. You will only need a little mana in the beginning of your game. And a lot of damage, throughout. That's pretty much it. Kinda common sense.

-Get the standard Defensive Seals (armor) and Glyphs (magic resist) and the usual Marks of Desolation.

-BUT for Quints; Either the get the ArP or the Flat Damage. I prefer the flat damage, it scales (obviously) with your Acid Hunter, and provides amazing early damage. The Masteries, the Marks, and the rushed Brutalizer all add ArP that when put together goes over the standard 30 starting armor. This means you will have extra armor pen that is doing nothing for you until level 4. They work, if you already own them, but the Flat damage Quints are DEFINITELY better, and make a noticeable early game difference.

-DORAN'S:
This is good to start, a bit of health, a bit of lifesteal and 10 more damage. That's 20 extra starting damage when added with your runes and masteries. That'll help get you the early game kills and out DPS their AD carry.

-THE BRUTALIZER:
Rush this. RUSH IT HARD. It offers CDR, and ArP and a hefty bit of damage early game when you also have your Doran's and Runes/Masteries. You'll still be in laning phase and wont need boots as you build it. Boots help, but the damage is more important for the laid back Mortar-style game play of Urgot's early game.

-BOOTS:
You have a choice of boots. You can either get the Berserker's Greaves if the team isn't AP heavy or they lack CC. Or if they ARE AP heavy and/or have a modrate amount of CC, then get the Mercury's Treads. I recommend the latter, but Berserker's can be good in certain situations.

-TRINITY FORCE:
Not many people get this item on Urgot, and I could have sworn it would be only moderately useful on him. Then I tried it, it worked, and I tried it several more times. It is an absolute MUST on him. It offers the Movement Speed, the Attack Damage, the Health, mana, the Sheen's Passive, and a nice slowing effect, all help Urgot directly. Plus there's some more to it that is useful, but not worth mentioning. Just read what it does. And buy it.

-FROZEN MALLET:
The Health on this ****er combined with the bit of damage, and the damage that gets added from the future Atma's, is enough reason to buy this alone, but the Passive Movement speed reduction against enemies you attack... perfect. This ads survivability, damage, and increases the ganky-ness of Urgot. And yes, it stacks with the Shield (W) and the Trinity Force.

-ATMA'S IMPALER:
Adds, armor, more crit to stack with your Trinity Force, and a butt-load of damage too. Get it.

NOTE: That is the main part of the build the rest is just what is recommended, not core. ALL SHOULD BE THOUGHT OUT, THESE ARE SITUATIONAL. Welcome to late ( and ****ing increda-late) game.

-THE BLOODTHIRSTER:
Adds up to 100 damage, (great), and up to 30% lifesteal (I think?) and greatly improves the damage output. CAN be REPLACED by LAST WHISPER, THE BLACK CLEAVER for damage or BANSHEE'S VEIL or RANDUIN'S OMEN for defense.

-GUARDIAN'S ANGEL:
Adds great defense, seeing as how if you made it this late game, you'll probably be needing it. And a smart passive, this item is the ****.
