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.
After being away for a while, I decided to come back with a guide with myy new favorite champ, Urgot. Urgot is quite an odd champion, being very good in early game, but can be lacking end game. This is how I build and play Urgot.
Early Game: Make sure that you get mid, and focus on keeping your enemy from killing many minions. On level 1, make sure to use your charge to clear minions quicker. Try to hit minions and your enemy champ in a charge so if the champ gets away fast enough, you have some minion kills.
Mid Game: Focus on getting ganks and easy kill with your 3 normal spells. Use your ult to get enemies into your turrets or allies.
End Game: Pick off any champions that run from your team. Urgot's auto attack is quite strong, and can 1 hit some fleeing champions.
