How to play as Olaf

Freeze the wave near your side and look for fights when your ultimate and summoner spells are available; an Olaf player recommends using those windows to kill Nasus before he outscales you. (Unverified: no source confirms this note.)

In an all-in, save Ignite until Nasus is below half health rather than using it at the start. (Unverified: no source confirms this note.)

Wither(W) slows Olaf, while Ragnarok(R) makes him immune to disables during the active chase as long as he keeps attacking.
