With the new Olaf W buffs, I present to you Zzrot Olaf top

Get a vamp scepter as your first item, run warlords bloodlust, and avoid fighting your laner directly as much as possible(don't do that vs a Nasus though).

Now why would you do that? Well you silly goose with the new Olaf W and R changes, he can now be way harder to push out of lane than before.

You're vs a Quinn top? Ignore that bitch and farm till you get Zzrot, if you drop below half health, hit that W to heal for about 40 health every auto on minion.

Once you get Zzrot, put it right behind your turret and proceed to push harder than your mother giving birth to you.

You will be such a toxic force top lane that nobody can deal with because if you do get ganked(and you will attract MANY enemies), just hit R if they have CC and run away. After Zzrot get some health items or finish vamp scepter into a Ravenous Hydra.

Have fun with this toxic build summoners :^)
