The synergy behind (Mobi boots) Predator, Cheapshot, Relentless Hunter, Clerity, Waterwalking, Deadman's Plate, Duskbalde of Draktharr, Black Cleaver, and Stormrazor is crazy. Everything either adds damage to your next AA or increases your movement speed. Nothing has been more satisfying in all my league of legends play than when there is a lonely ADC farming in lane, I pop Predator and start zooming through the jungle at over 800 movement speed. Seriously, Garen comes flying out of the bushes and damn near one shots any squishy on the enemy team. Q>E win. 9/10 They usually die before the silence is over without having to use your ult. Then you run back into the bushes and do it all over again. League guerilla warfare. There will be a lot of people that scoff at this and that's fine. This build carried me from Iron to Gold. That may not be much to some but I am terrible at this game and it took me 6 years to see gold for the first time. This probably wouldn't work in higher elos but its soo much fun.

Laning Phase: you'll want to rush lvl 2, by then your boots should be close to coming off cd. My first roam is usually to mid at lvl 2. Even if all you get is a summoner that's fine. You'll normally come back to lane and the enemy will be a lvl ahead but you'll have the same cs. From here its all max E so you can push your lane, roam to mid or even bot if your tele is up to get back to top. If you lose your tower it shouldn't be that big of a deal as long as you have helped the other lanes et ahead. keep mindful of where you may want to tele and place a ward there or ask a teammate. Most of them will be very accommodating once they see what you are doing. And I take scuttle anytime its up. If my jungle isn't there to get it, then the enemies might be. And it's better that you get it than them lol. I've also been known to take enemy wolves and Gromp. Only do this if you have good vision of the area.

You will want to position your attack so that you are in the enemies vision as little as possible. Support classes tend to put you in CC hell. Obviously snares, slows, and knock-ups are the bane of this build. Build with good bush positioning they will be dead before they get the chance.

For team fights, you will want to flank the enemy team and take out their ADC/squishy support/ mid. most of the time when I do this I can get 2-3 of the enemy team before going down. And then it's 4v2... GG (normally).

Lvl 11-15 is the sweet spot for this build. Your regen is enough to mostly recover after every single guerilla attack. Running is key with this build lol.

Have thick skin when running this build. You will get called all sorts of stuff lol. Oh, and people will ping your duskblade. They tend to stop doing that once you are 7/0/5.

And in my personal experience, I have had several enemy mids curse my existence and poop their pants because of how scary Garen was flying out of nowhere like Arya, and then how helpless they felt being silenced until they died.

Have fun out there!
