Urgot is a Caster/Melee, requiring you to also use skills to help take down opponents other then right-clicking on them and wait. If used correctly Urgot can can harass and do large amounts on damage in early game. Using Noxian Corrosive charge can help increase your range on Acid Hunter and will auto-lock on to the opponent as well as poisoning them and reducing there armor for a short time. Rushing sheen at begining is a good way to large amount of damage by casting Acid hunter and attacking right after, as well as giving you more MP being able to harass more. If u cant afford the rune pages try getting Last Whisper or GhostBlade instead of Banshee's Veil. This will give you more armor pent. replacing your armor pent runes. then i added Stark's Ferver and Hextech Gunblade for last because depending on how long your game is or how much money you have. i recomand getting Stark's Ferver because it's a cheap item to get and it also helps teammates around you gaining Life steal as well. In very late game if you have money to spend on nothing i recomand selling Stark's and getting Hextech Gunblade for more life steal(acid hunter works with spell vamp giving you more HP per damage) and damage.
