Hello my name is 00Boom and welcome to my very first guide!
Don't let the thought of Urgot support scare you away!
I know it sounds crazy but hear me out.
Urgot brings a lot to the table to help an ADC out.

For offense: He has so much spammable long range poke to get the enemy ADC and support low, giving his ADC easy kills. If your ADC can't secure the kills, take them. A fed Urgot is Urgodly anyway.
Once you get fed, or get your ADC fed, roam, gank lanes, and go in the enemy jungle and steal buffs or kill their jungler. Urgot has a lot of 1v1 capability.
The only things an Urgot can't really 1v1 are duelers. Tryndamere, Aatrox, Olaf, and things like that will destroy you. Mage junglers are easy pickings for Urgot though.

For defense: As they say, the best defense is a good offense! Because of how much control over a lane Urgot has, the enemy team will be scared. You should be able to keep both the enemy ADC and support very low on health. If they go on your ADC, use E, then W, then spam Q on them to either set up kills for you or your ADC, or worst case they'll have to disengage.
Same goes for if you see their jungler in the brush getting ready to gank. E, W, Q, Q, Q him. No one likes sitting in the brush having their health chunked every second until they die.

Once you hit 6, you should let your ADC know before you're going to ult. Your ult will give any competent ADC a free kill every time it's off cooldown, OR, it will let him escape a bad situation.

This guide is far from complete, I am typing it at college on a ****top. Please bear with me as I make this guide FAR more in-depth, and fix up the item build a bit. Thank you for your patience!
