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.
Ghost: who doesn't love ghost on a slow moving champion.
Exhaust: encase you over extend your self.
Skills i like the most on Garen.
Decisive strike: Procs on all and gives you great speed and damage output
Courage: Gives you great passive for armor and magic resistance and on active gives you 35% in damage reduction for both magic and physical(makes all mages and physical go what the when they dont deal damage to you :) ).
Judgement: gives you immune to snares and slows while dealing damage per second to people around you.
Demacian Justice. great for last hitting other tanks or really annoying dps people.
Items to buy in order OK.
Boots on 2 health pots, save up for MT and probably 1 or 2 of the items to make phage if you got lucky and got double or triple kill. Than save up for frozen mallet and buy another giant belt if you got enough cash if not go farm and buy a Sunfire. Next you want a GA so start constructing it 1 item at a time. Than start the construction on Randuin's Omen for team fights cause you might be facing one of the many AS champions. Start constructing the Banshees Veil next. Than if the game is still in progress you can sell your Sunfire for Warmogs and if it still continuing you can sell your MT for trinity force for the damage health and such. you should have a good 5200 hp and a good 100% damage reduction in magic and physical every time you pop your courage skill. I am open to suggestions about my build.
