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 has been tested and it's fool proof, any dumba** can play Olaf, but do you know how to rape? This is how, just. keep. attacking. don't. stop. if you try running away you will miss out on precious health and good amounts of damage, your auto attacks will keep you alive plus your W will practically shred there health to activate your Stormraiders. Poke with your Q early game just to piss them off and keep them away from the minion waves whilst your farming. also its required to chant "RAGNAROK" when you get killstreaks for a viking-like effect. But yeh that's it just W R when engaging the enemy and use your e for last hits. That's pretty much it.
