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 is a tank build for garen, the might of demacia. one item that can switched around if you wish is the merc treads. the item that i would suggest switching it for is boots of swiftness, since they give so much speed. since your a tank, boots of mobility would be pointless because you should be in combat almost constantly. another thing that can be interchanged is heal or cleanse for exhaust. i would suggest cleanse, but if you think taking out heal would be more effective, then by all means do so. i just find that the heal is nice, especially for the mirror match, since most garens dont pick up heal, its a nice surprise for the other one when you pop it and get the advantage. frozen heart is almost a staple for tanks, and some non tanks alike. merc treads are the same, and make up for some of the lost magic resist. the runes are all magic resist/ lvl because you would end up with minimal magic resist otherwise. this build is an all around tank build, you get a lot of life, you get high armor, high magic resist, and with guardian angel, you get a free resurrection. all of that, plus garens naturally high damage output. whats not to love? PLEASE VOTE, and if you downvote, please say why so that the mobafire community, and myself can learn more about garen. HF and GL playing garen, the might of demacia!
