Olaf is one of the safest strongest early game junglers in the current meta and is very powerful in the early and mid-game. He is very good into laners who rely on CCing the enemy to escape or kill, like Yasuo Syndra Hecarim or Skarner. However, he is quite bad into enemies who scale if you cannot end early game, like Kha'Zix Kayn or Master Yi. While Olaf can be easily kited, Turbo Chemtank is a fantastic item that you should get nearly every game that makes you almost impossible to shake off. When playing as Olaf, you should look for early ganks and objectives (You can solo dragon as early as level 5 very easily), as well as invading the enemy jungler frequently due to Olaf being one of the strongest early game champions in existence.

Be Warned: Olaf falls off very hard starting generally around the 25 minute mark, so try to end as early as possible.

Pros:
- Very strong early game
- Strong clear and sustain
- Very high damage
- Easy to pick up
- Few hard counters
- Strong chase and escape
- Low cooldowns


Cons:
- Mediocre ganks
- Falls off hard
- Mana hungry and dependant
- Awful if behind
- No hard CC
- Easily outscaled

Note: What side Olaf start doesn't generally matter so I prefer to start botside for a stronger leash.

- Wolves

- Gromp


Blue Side Start;

How to clear effectively with Olaf

Olaf's clearing is very simple, while a lot of other jungler will need to kite camps, like other junglers, you want to pull aggro from as far away as possible with a max range Undertow (You don't have to worry about picking up the first axe) to be as time-efficient as possible. Next, you want to get the monster as close to a wall as he can, and throw an axe at minimum range at the wall so that you can immediately pick it up (without having to move) and refreshing the cooldown. This allows for Olaf to have disgustingly fast clears. MAKE SURE YOU DO NOT USE SMITE OR POTIONS (UNLESS YOU ARE BEING INVADED) UNTIL YOU ARE ABOUT TO CONTEST SCUTTLE.

Alternate Olaf Start

This Olaf start is very risky, and should really only be done if the two following conditions are met:

1). Your bot lane (something like Blitzcrank Draven) wants to level 1 cheese the enemy
2). The enemy jungler has a near-zero percent chance of invading you.

If these conditions are met, you want to start red leashless and use your first point in Tough It Out, holding it when you are about 40% health (the lower health the better, but using it any later makes it unavailable for your next camp).

DO:

- Throw you axes in directions where the enemy is going to run
- Use your axe to scout bushes, or otherwise scout where a champion may be
- Use Ragnarok liberally (its cooldown is really short)
- Learn proper auto attack reset timings (this is one of the most important champions to learn it on)
- Learn to hold Tough It Out until you are at a lower HP for maximum attack speed and healing
- Combine Reckless Swing with Smite to securing objectives that would otherwise be 50/50

DON'T

- Always throw axes max range
- Wait to get CC'd to use Ragnarok
- Underestimate Olaf's ability to win fights. Olaf's passive and healing makes him a champion that's really good at clutching out tough fights (If ahead enough you can 1v3 easily)
- Give your blue buff to your mid. Unless they are carrying, Olaf is extremely mana hungry and becomes weak quickly when fighting outside the jungle.
