Playing against Olaf

How to counter and exploit weaknesses

1

Kite him: without his R, Olaf can be slowed and CC'd easily. After his R, wait for it to expire then CC him.

2

Don't fight Olaf when he's low on HP: his passive makes him more dangerous at low health, not less.

3

His R has a relatively long cooldown — track it and engage when it's down.

4

Ranged champions with CC counter him: he has to run toward his target with no dash.
