Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
CRABMAN WILL KILL YOU!
AD = Attack Damage
AH = Acid Hunter
TC = Terror Capacitor
NCC = Noxian Corrosive Charge
HKPR = Hyper-Kinetic Position Reverser
Okay for this build it is basicly a AD build because of urgot's main ability Acid Hunter and his normal attack. The description will descirbe how to lane with urgot and how to be a very effective support/nuke.
For laneing you are a huge harassment Acid Hunter has a long range and when you hit level 2 you are able to increase it with NCC. When you lane you want to make sure you can stand in a area to where you can hit the enemy champion with Acid Hunter as much as possiable. It IS OKAY TO HIT THE CHAMPION AS LONG AS YOU ARE BEHIND --->YOUR<--- MINIONS. But the laneing phase is fairly simple considering you can harass at level 2 when most people cant. At level 4 you will get Terror Capacitor, it will allow you to slow enemies and absorb damage like Karthus's ulti great for that.
For the ganking part of the game you will want to help gank as much as possiable cause.. see the item build.. if you dont.. your blind. it might be expensive but will help out in the long run it has the power to almost 3 shot people.
At end game if you got your items right you should be basicly unstoppable might die once or twice if you get to jumpy but other then that stick with the team unless you want to pull a Ima Best and go solo people (NOT RECOMMENDED).
NUKE INCOMMING! 5.. 4.. 3.. 2..
For this you will need to be level 6 and know some what about Urgot to know when its a good choice or not. How to be good to nuke with this guy is TC --> HKPR --> NCC --> then spam Acid Hunter best way to kill someone if you need to flash to keep up with your prey. I have Clarity on this build because of the mana you dont have it is very easy to burn mana and lose a kill so you have a back up source.
Ganking will be the best way for you to get gold. You should start nuking/ganking at level 6 because if you do this you should be getting your items quick. Ganking if you dont know you honestly should not have Urgot he is a great support but best gank if played right.
This is just the way I play Urgot, im not saying you will do a perfect game but you will get kills... the joy of killing.
