So I have a lot of fun with this build. I hope you enjoy :D

Well, I'm new to the whole rune thing but I like to have attack speed. Like a lot. It really helps on his health regen. Then I have basic defense runes. My quints, however, are a bit different, but I like to be strong and scary. This Olaf will run other champs down lane its not even funny. Then I have a quint so I can be stronger.

I like to be semi tanky, but still aggressive af. So I go with 13 17 0 for the perfect balance, I believe, for Olaf.

This build would scare teams down lanes, out of jungles, and even back into their base. You clear waves like a champ, stay in lane, be a DOMINANT FORCE in team fights. He's op.

I'm not sure when you're able to get abilities to the tee, but I do know that with Olaf you have to rush Reckless Swing. BUT BUT BUT, don't start with it. I get my Q so I can poke even with ranged champs, then I get my W to sustain in lane (no use for red pots), then I rush E, followed by W, then Q. I mainly use his Undertow just to slow the enemy and with the runes on here, you can catch up to most champs even with his Q because of his resets.

I run Ignite and Teleport so I can secure kills and be a global threat whenever the time calls.

I hope you enjoy this build. I have fun with it and I hope you all will too :D

He's scary, strong, and you can't mess with his Graggy Ice.

I usually go for the ranged creeps first especially if my enemy champ is melee because I have my Q to poke. Then when you get Ravenous Hydra, clearing waves are nothing.

When I see a team fight, about to occur, I either run or tp to a ward or tower nearby. Then I rush in, pop my ult, my w, ravenous, and you're pretty set from there. But there are stragglers so I usually chase them down with my Q.

His life steal is OP. Take advantage of it and his chasing abilities.

He's fun to play, but he can be handful when behind. But to be honest, most champs are. Play to your best ability and just have fun, get the items, and you'll have more fun wrecking the other team.
