Win Lane, Maybe Win Game
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.
If there is no ap on the enemy team or it isn't a huge factor you can take mana regen if you wish or cdr flat or scaling (depends on the items you choose to build, but youre gonna want 40% cdr).
If the enemy tank is lacking tanks, replace armor pen runes for flat damage. Attack speed does not benefit Urgot. (Taking 2 flat CDR quints and 6 flat cdr glyphs will give you 10% from level 1 and allows more room for different items)/
