Garen is one of the cheapest champs in the game. For only 450ip you can unbound the Force of Justice. Garen is really easy to play, so you should concentrate on general gameplay mechanics. As jungle garen your task is to clear the camps, get buffs, kill objectives, gank all the lanes and carry the **** out of the game. Garen is a really strong champion especially in low elo solo queque games. You should pick him if you want to play a tank thats fun to play, but which can still carry games 1vs5 and deals insane amounts of damage.

To be honest... Garen sucks pretty hard if the enemies aren't totally ******ed.
The point in solo Queque is.... they are. The lack of communication and teamplay in such games are great for Garen. Because.. he doesn't give a ****. He just spinnin' and he winnin'

And the light will shine.

You can spamm your spells on the jungle camps, because well... you have no mana.
Thats op. But wait. There is more! That means you can give the blue buff to your mid. Anyway you should get the red buff by yourself, Garen is a champion without any cc, so red will help. If you should ever run out of HP just get out of the battle and wait for the passive to drop.

test him in a normal game first

Carry potential -> Noobkiller
can destroy towers -> Q op
heavy tank -> Tankmeta
Viable -> Always a great pick
