I play Olaf pretty aggressively. It works most of the time when going against melee champions, but most ranged champions play more passively and taking them out would become a lot harder. Should I play more passively then aggressive when the chance comes? Or is there any other tips?

Ravenous Hydra is the core item for Olaf, and you don't use it, why?

your thoughts on revitalize instead of Overgrowth?

Overgrowth better vs poke/burst, revitalize better in sustain battles?

let's say it's early game. you've got about 40 minions. Overgrowth will give you 3hp*40/8=15hp.
revitalise wil impower your w, when at 40%hp, from 14% and the 30% extra from missing 60% hp. so 18,2%lifesteal to 20,93% lifesteal, an increase of 2,73%. so you need to do about 550damage with autos in the 6s your w is on, that seems doable. mind that it's less if your above 40% hp but alot more the closer you get to 0%.

late game. Lets say you have 250 minions and 4,5k max hp you get about 250bonus hp.
you propebly have spiritvisage, so 130%*115%=149,5% from healing if below 40%hp
your w heals you for 22% at lvl 18. with buffs it's and extra rufly 11%.
So you need to do 2273damage over the 6s your w is on to get the 250hp more in lifesteal your missing from max hp.

The late game damage seems hard. thats a bit less then 400damage pr/s. But my healing calculations does not take conqueror healing into the mix... 8% damage as true damage heal for that, with the 150%healing thats another 4%, so 11%becomes about 15%. and 2273 becomes about 1670damage in 6s or now less then 300damage pr/s. With high attackspeed and conqueror running, that should be possible. But it requires conqueror to be running all the time while w is active.
But the added benefit is we stay alive longer at low hp, dishing out more damage pr. second.

I gave you some numbers, have you tried it? your thoughts?
my hope is you get even stronger early and don't fall of to hard late.
I would defenetly NOT do this vs something like and urgot, since he will just execute you when low hp, and more hp is better. but if you are not against and execute and have other heals or shields on your team. especilly if they also have revitalize, this becomes even stronger.

Nice guide now i winning almost all games thanks man

I've followed your guides for a while now, and you are my go-to guide for learning any new champ. This guide is one of my favorites because of how you lay out the situations for which Olaf thrives in and lay down a comprehensive structure on how to play the champ. I'm always in support of any guide you release, and this guide will definitely make me a Diamond Olaf.

Here comes another great guide for the Berzerker !

Especially appreciate the clear advices on various playstyles as well as the in-game resume.

Also well done grabbing the honorable mention of the S8 contest, most deserved +1 :)

not bad

Where is mid?
