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.
This build stacks Armor Penetration and DMG with some Lifesteal/A.Speed.
1 - Ulti
2 - Acid Hunter
3 - Noxian corrosive charge
4 - Terror capacitor
Max ACID HUNTER as soon as possible for more base damage.
Next go for Noxian corrosive charge for auto lock on for acid hunter AND extra Armor Penetration.
For the Terror Capacitor one point is needed for the slow so you can gank and kill champions better at lower levels until you get your Phage/Frozen Mallet
Basic strategy for AD Urgot
1-Drop poison on target champion
2-Turn on shield (for slow)
3-Spam your projectile of death
4-Press B and get your items.
Strategy for this Urgot build
Start off w/ mana crystal and two health pots.
FIRST TRIP - Conserve mana for harass very early game until you have Tear of the Goddess, and then SPAM SPAM SPAM xD.
SECOND TRIP - Get Boots of Speed and a sword or a manamune if you can.
