Olaf is an extremely potent jungler, which is the way that I most often play him. He has amazing sustainability while in the jungle and has an extremely fast clear time. His ganking capabilities are very unique and he is generally just fun to play.

This is my first guide here on MobaFire and I tried to put as much information as I could think of into this guide. I really hope you enjoy it, please play it before you rate it! Just a note, sorry if my pictures are all broken it happens way too often and I'm not always near a computer to fix it.

Berserker Rage, Olaf's Passive, increases his attack speed by 1% for every 1% of his own total health missing. This is an excellent passive for jungling since Olaf will take some damage his first few levels. Berserker Rage is truly underestimated, it can change the outcome of a fight if he is at a low percentage of health and nobody focuses him. Don't get too cocky though, because Olaf is not invincible.

Undertow, Olaf's 'Q' Ability, Is a skillshot slow with an adjustable range, meaning you can choose how far the projectile will be thrown. (Roughly the same max range as Lee Sin's Sonic Wave / Resonating Strike) This skill, in my honest opinion, is what separates the good Olafs from the not so good ones. Undertow is Olaf's only form of CC, or Crowd Control. This skillshot will cause Olaf to throw an axe that will cause damage and leave an axe impaled to the ground, granting sight for a brief moment. This axe can be picked up if walked over and it will lower the cooldown of the ability by 4.5 seconds, however if it is left on the ground after 8 seconds Olaf will get it back automatically. This ability can make or break a gank. If an inexperienced Olaf throws his axe at maximum range even though the enemy champion is only half of the range away, you are putting your only way of CC out of combat range. Be careful when throwing using Undertow because you don't know when you'll get a chance to pick it back up.

Mana Cost: 55/60/65/70/75 per rank up
Attack Damage: 80/125/170/215/260 per rank up (+1 per bonus Attack Damage)

Cooldown: 8 seconds flat

Vicious Strikes, Olaf's 'W' Ability, is an activation that instantly grants him Attack Damage, Lifesteal, and Spell Vamp. The Lifesteal and Spell Vamp are only based on rank, but the Attack Damage scales off of Olaf's maximum health count. 1% of Olaf's health will convert to Attack Damage, similar to Atma's Impaler. Vicious Strikes is what makes jungling easy. Not only does the lifesteal keep you up but Smite scales off Spell Vamp, so if you activate this ability then use Smite, it will heal you.

Scaling:
Mana Cost: 40/45/50/55/60 per rank
Attack Damage: 7/14/21/28/35 per rank (+1% of Olaf's total health)
Lifesteal(%): 9/12/15/18/21 per rank
Spell Vamp(%): 9/12/15/18/21 per rank
Cooldown: 12 seconds flat

Reckless Swing, Olaf's 'E' Ability, is a target nuke with similar range to Rammus' Puncturing Taunt. This ability causes true damage, meaning it ignores all resistances. This ability does excellent early game damage, which is why I max is first. Unfortunately, this ability also does excellent damage to yourself. Reckless Swing will hit both you and your target with true damage. The damage you do to yourself is significantly lower, but you need to be careful when using this at lower health, for you may get yourself killed.

Scaling:
Health Cost: 40/64/88/112/136 per rank
True Damage: 100/160/220/280/340 per rank
Cooldown: 8/7/6/5/4 seconds per rank

Ragnarok, Olaf's Ultimate Ability, gives him a passive increase to armor penetration.

This ability also grants Olaf bonus Armor and Magic Resistance on activation to make him an unstoppable force.

Scaling:
Mana Cost: 100/75/50 per rank
Armor Penetration: 10/20/30 passively per rank
Armor: 30/45/60 per rank
