This is only a Garen Build, this is not a guide how to play garen, but just a simple build that i love on him, that makes him the hardest to kill and the best dmg output ever seen (;
Normally i would use the first build (Team 1) cuz i like to be hard to kill + DECISIVE STRIKE and JUDGMENT will rape everyone and if getting attacked or running into a team fight remember to have COURAGE ready, use your ultimate if some1 with low hp try to run away from u, or maybe a little Killsteal xD.

Thanks for Viewing my Build and please try it, it works for me on Garen (:

Throughout Valoran, the resolve of Demacia's military is alternately celebrated or despised, but always respected. Their ''zero tolerance'' moral code is strictly upheld by civilians and soldiers alike. In combat, this means Demacian troops may not make excuses, flee, or surrender under any circumstance. These principles are espoused to their forces by unrivaled demagogues who lead by example. Garen, the valiant warrior who bears the title ''the Might of Demacia'', is the paradigm to which these leaders are compared. Thousands of great heroes have risen and fallen on the bloody battlefields between Demacia and its preeminent rival, Noxus. It was beneath their mighty banners of war that Garen first met steel with Katarina, the Sinister Blade. The infantrymen who beheld this event (and survived) commented that it seemed as though the two were locked in a mortal waltz against a symphony of clashing blades.

Garen, the pride of the Demacian military and leader of the Dauntless Vanguard, returned from this battle breathless for the first time in his career, though some speculate that this was due to reasons other than exhaustion. The plausibility of these rumors was bolstered when, in every instance thereafter, Garen seized the opportunity to encounter the Sinister Blade again. A paragon of Demacian ethic, Garen never entertained such allegations, for he knew others couldn't understand. Even simply the pursuit of a worthy opponent on the battlefield is, to a true warrior, the reason to rise each morning. The promise of one, particularly so beautifully and diametrically opposed, is the validation of his existence.

''The most effective way to kill an opponent is to slice through the man next to him.'' - Garen, on front line strategy

DECISIVE STRIKE

: Garen's next attack strikes a vital area of his foe, dealing bonus damage and silencing them.

COURAGE

: Garen's kills increase his armor and magic resistance. He may also activate this ability to give himself a damage-reducing shield.

JUDGMENT

: Garen preforms a dance of death with his sword, dealing damage around him for 3 seconds, and reducing the duration of slow by 50%. garen removes any slow effects on him at the start of the dance.

DEMACIAN JUSTICE

: Garen calls upon the might of Demacia to deal a finishing blow to an enemy champion that deals damage based upon how much life his target has missing.

Pros

+ Heavy Tank
+ Hard to Kill
+ Good DMG Output
+ Good mixed Armor, Magic resist, Health
+ Good Escape

Cons

- Cooldown

- No Taunt (if enemy's dont focus you, and kill your team ;(

Playing as Garen:

* Garen's regeneration greatly increases if he can avoid receiving damage for serveral seconds.
* Try to kill lots of minions to increase the effectiveness of courage.
(* Garen is only constrained by cooldowns, making items such as Youmuu's Ghostblade and brutalizer very effective for him.)

Maybe as DPS but not in my build (:

Early Game: Try to last hit minions to get gold and try to get as mush exp as possible, The reason that u should Last hit is to get your Sunfire Cape as fast as possible, i myself buy Dorans shield as starting item, then i rush my swiftness boots and then sunfire cape (:

Mid Game: Mid game i normal still lane, unless i got the tower then i go gank, and just make some free farm for myself, when u have sunfire cape its so easy to farm and get gold, so u can do more dmg and take more dmg.

Late Game: Late game i still farm minions to get oracle etc ward, ward on baron and dragon and in our jungle and enemys ramps and buffs,

Try to catch as much Exp as possible remember to last hit minions to get the gold.
When you come level 4 use your DECISIVE STRIKE to last hit minions.
Remember to get fully stacks on your COURAGE when you level it (:

Well when Mid game comes the Laning phase is over. Start ganking mid and help in team fights if it starts so early.
Remember to have a ward at dragon so you can gank enemy if they try to take it.
Try to Protect your towers and keep the jungle clean so the enemys dont steal jungle minions.

Now your in Team Fights for sure (: and u must have almost all your items and your ready to take some dmg.
when im in team fight i always run in first with my DECISIVE STRIKE i try to hit the carry if possible, Then ill yell "DEMACIA!!!!!!" and (Spin for the Win) with my JUDGMENT to get them low (: and ulti if some1 try to run or if some1 is on low HP (:
and if i get stunned or if they get me low i will run out with DECISIVE STRIKE and use my COURAGE while im getting attacked (:
Keep the enemys on you or near you, so your team can push bot and top lane while u just play with them mid (:
or as i say "Push and Win"

Try to Help your team as much as possible, if one of your team mates are trying to run away with low HP and you see an enemy try to catch him Jump in with your DECISIVE STRIKE to silence the enemy after that pop your JUDGMENT and get away safely self (:
You can be a good team player and u can make a good team work, if you have a Katarina or a Akali on your team and a enemy is low on tower i know akali or kata is greedy u could use your COURAGE to tower dive so they can make a fast kill and get away safe (:

Ill add some Screenshots and Gameplays later on (:
