Olaf Only's Challenger Top Lane Guide [10.19]

By Olaf Only
My name is Olaf Only and I've been playing Olaf Top since Season 4.
I have reached Challenger multiple times, (peaked at rank 87) and have over 5 Million Mastery points on Olaf.

I'm a streamer on Twitch.
I also have a Youtube channel with Highlights, Tips and Guides all surrounding Olaf.
Back to Top
If you're looking for a fun and engaging champion that never gets boring no matter how much you play, Olaf is the perfect choice.

I have attempted to main a lot of different top lane champions such as Rengar, Riven, Renekton and Lee Sin.
However Olaf is the only champion that I never got "bored of".

You also see a trend here that I played mostly early game focused champions, which to me is way more fun as you don't need to farm for 20 minutes before you actually can do something like most other champions.

Once you get a lead with Olaf(which is very common), you will never die to ganks and you can 1v2 everytime you have Ragnarok ready.
Translating into teamfights you will become an unstoppable meatshield that can kill any target of your choice while the enemy team helplessly attempts to slow you down.
Back to Top
+ Godlike early/midgame
+ Cannot be CC'd, enables you to kill important targets.
+ Fun to play with a lot to learn
+ Consistant build path

- Useless lategame
- Bad against high mobility teams
- Requires a proactive playstyle
Back to Top
Runes for Olaf are pretty straight forward but there are some slight variations that should be considered.

Precision is pretty much mandatory as your Primary Rune Path.
Conqueror, Triumph and Last Stand are undeniably the best runes in this tree.

Chosing between Legend: Alacrity, Legend: Bloodline and Legend: Tenacity is a lot more difficult.

Legend: Tenacity is never used on Olaf because it doesn't give combat stats and it has anti-synergy with Ragnarok.

The more interesting comparison is between Legend: Alacrity and Legend: Bloodline.
In short: Legend: Alacrity is better early game while Legend: Bloodline is better mid to late game.

/Credits to @MHLoppy for this comparison

The Secondary Rune Path is a lot more debatable with plenty of viable options.

In short: Inspiration makes snowballing easier, but you don't get the combat stats that Resolve and Domination provide.
Sorcery empowers your movement speed with Nimbus Cloak which can save you from ganks and enables better Teleport roams.


I'm only gonna be covering Inspiration in this guide as it is what I personally use and it's the most popular choice.

Approach Velocity

Gives you 15% movement speed towards enemies hit by Undertow.
Increases Olaf's kill pressure in lane and in teamfights. Closing the gap against most champions is very difficult but this rune makes it easier.

Cosmic Insight

5% CDR from this rune is really good on Olaf.
It may not look like much, but you will be able to spam Undertow faster which will increase your DPS and keep enemies perma slowed.

Biscuit Delivery

After 6 minutes you get +150 maximum mana, which is enough for 3 extra Undertows.
Since Olaf can't build viable mana items early on, this becomes very valuable as Olaf is extremly mana hungry during the laning phase.

Time Warp Tonic

Has to be used in a specific way*
How to use (video):
Or read my "Advanced" Rune page notes

Magical Footwear

Very good for midgame as you save gold and get max Movement speed.
You can't buy Boots though, so your early game will be weaker compared to Biscuit Delivery.

Perfect Timing

Doesn't help you in the laning phase and has very situational use.
Would not recommend.

Hextech Flashtraption

Again, a very situational rune that Olaf doesn't use to great effect compared to other champions.
Does not help you win lane or get stronger.

Future's Market

Helps you get item power spikes faster and can situationally be a game changer.
Definitely a contender with Biscuit Delivery.

Minion Dematerializer

Olaf already has good waveclear so this isn't necessary.


You want Diamond in both slots because Olaf has insane AD ratios which increases your Undertow damage, Reckless Swing damage and Ragnarok bonus damage.
As for the final slot, you can take Heart vs easy matchups or Shield/ Circle depending on the enemy team.
Back to Top


Gives you a safe laning phase and can be used as an instant gapcloser for fast burst combos.


Gives you a riskier laning phase but in return makes it easier to snowball in the 1v1.
It also prevents Olaf from being kited in teamfights as much and enables Olaf to spam Undertow faster for more damage.


A must have if you want to impact the game as a toplaner.
Enables you to turn the tides of fights around the map, especially around botlane.
Gives you more XP in the 1v1 compared to Ignite, as your backtimings won't be an issue.


Increases your kill pressure in lane and in teamfights.
However it makes roaming next to impossible and you tend to fall behind in XP compared to Teleport.
Back to Top

Common items

Corrupting Potion

The only viable Starting item that gives you extra mana and is required if you want to last hit minion s or poke with Undertow.


Extremely cheap and gives Olaf a massive power spike compared to what other champions typically build.
After lvl 6 you simply can't lose with this item.
The 10% CDR makes your Undertow spam much more effective in both damage and slow.

Doran's Blade

If you don't have enough gold for Kindlegem, get this as it is really strong on Olaf early.
Can also be a good starting item vs certain Melee Champions while using my "Advanced Rune Page"

Ninja Tabi

Usually the second item if you're against AD champions such as Tryndamere, Irelia, Renekton, Kled etc.
The movement speed increases your kill pressure and makes you more durable in fights vs certain champions.


Not the greatest item by itself but it increases your kill pressure with more movement speed and durability.
Is required for Black Cleaver*

Black Cleaver

Yet another BIG power spike for Olaf.
Completing this item will give you additional movement speed on every Undertow you hit and 10% CDR for faster Undertow spam.

Jaurim's Fist

The most cost effective part of Sterak's Gage.
I like to get this after Black Cleaver most of the time.
It's a good middle ground if you want both damage and tankiness.

Sterak's Gage

We don't care about the 30% Tenacity that it offers as it has anti-synergy with Ragnarok.
However, it offers AD and Survivability against burst damage that Olaf uses very well.

Glacial Shroud

Buy this after Kindlegem for a total of 20% CDR against AD heavy teams.
All of this together with Ninja Tabi will make you near unkillable with tons of damage from Undertow spam.
Builds into Turbo Chemtank*

Turbo Chemtank

Very good as a first or second item vs AD heavy teams or teams with high mobility.

Spirit Visage

The best MR item for Olaf.
Empowers the effect of Triumph, Conqueror and Vicious Strikes.
10% CDR for faster Undertow spam.

Randuin's Omen

The best late game armor item for Olaf if the enemy team has Crit.

Bramble Vest

The best armor item against Life steal heavy teams.
Build into Thornmail lategame.
Thornmail and Randuin's Omen do not stack.

Dead Man's Plate

The best armor item if the enemy team has No Crit.


Buy this when you know the game will be decided by the next teamfight and you only have 650 gold to spare.

Executioner's Calling

Cheap and good against Casters with spellvamp such as Aatrox, Cassiopeia, Dr. Mundo Illaoi etc.

Uncommon items

Adaptive Helm

Good against: Cassiopeia, Corki, Kog'Maw, Rumble, Heimerdinger etc.


Situationally good for Olaf if you're up against AP heavy teams or if you're laning vs Akali, Corki, Viktor etc.
Upgrade to Maw of Malmortius later.
Does not stack with Sterak's Gage.

Guardian Angel

Good lategame item against AD heavy teams.

Knight's Vow

In the VERY late game Olaf falls off hard, but this item makes you more useful.
It boosts your carries survivability and synergizes well with Olaf.

Youmuu's Ghostblade

Good if you're up against Vayne, Fiora, Kog'Maw or any other %MaxHP damage dealers.

Titanic Hydra

As a final item this can be good for more burst damage as it scales of your max HP.

Death's Dance

A superior version of Ravenous Hydra in my opinion.
Has a great build path, with 10% CDR.
It's also great against burst damage as the damage you take is delayed by 3 seconds which can give you enough time for Triumph to kick in.

Bad Items

Ravenous Hydra

Synergizes with Olaf very well in theory but it has no CDR which makes it hard to build early.
You have to Auto attack to make use out of this item, which is not easy as you get kited a lot.
It's good for split pushing if that's your thing.

Blade of the Ruined King

Terrible build path and is optimal against tanks.
You have to Auto attack to make use out of this item, which is not easy as you get kited a lot.

Frozen Mallet

You already have perma slow with Undertow and slows do not stack.
It's not terrible but i'd rather go Titanic Hydra if you want Damage + HP.


A weaker version of Death's Dance in my opinion.
Bad buildpath and relies on Auto attacking a lot, which is not easy as you get kited a lot.

Frozen Heart

Great item if the enemy team is full AD, but the extra mana isn't necessary and I would rather go with Randuin's Omen or Dead Man's Plate.

Trinity Force

A weaker version of Black Cleaver in my opinion.
Bad buildpath, very expensive and does not give you the movement speed after landing an Undertow like Black Cleaver does.
Black Cleaver gives you a better build path, more HP and AD for less gold.
Even if the enemy team has no armor i still prefer Black Cleaver.
Back to Top
Always go for early kills or trades if your matchup allows it. Typically you should go for short trades:
Undertow-> Reckless Swing->back off.

Against Ranged champions you have to poke with Undertow.
Be careful not to push the minionwave though, as you are vulnerable to ganks!

Try to freeze the lane towards your own turret , that way you won't die to ganks and you can potentially go for all-ins.

Don't bother going for turret plates before 5 minutes*

Your goal in the early game is to get Kindlegem by level 6.
This is your early power spike that enables you to snowball by forcing All-ins.
Back to Top
Once you are past lvl 6, try to deny your enemy laner as much as possible by freezing the lane and going for kills.

When your Teleport is available again, look for botlane flanks.

Always help your jungler and try to predict whats going to happen in the next 30 seconds so you're ready to respond.

Save your Flash or Ghost if you can for the upcoming Baron teamfight, as it is the most important time of the game.
Back to Top
Your early and mid game impact should enable your team to close out the game.

Try your best to Kill their carries in fights
Protect your most valuable carry.
Back to Top
If you use Ragnarok before Teleport you can avoid being interrupted and escape ganks.

Save Reckless Swing for the final blow on champions and minions. Otherwise, you will not refund the HP cost!

Use Vicious Strikes to heal faster in Fountain, get more HP from Honeyfruit-plants or to increase the healing from Corrupting Potion.

Make use out of Ragnarok's full duration. For example, if you are chasing Tristana with Buster Shot ready to go, use Ragnarok just before she starts casting Buster Shot.
Or if you are fighting Poppy, use Ragnarok when you think she is gonna knock you away with Keeper's Verdict.

Whenever you use Undertow, throw it as short as possible while still hitting the target. This will maximize your all-in damage and efficiency.

Whenever you get minion aggro from a trade, go into a Brush as soon as possible to drop it.

Generally, you should always use Teleport after your first back. Otherwise, you tend to fall behind in XP which is very important in the early game.
Your other Teleports should be used for objectives or flanks!

The best advice I can give you is to play A LOT of games. This shouldn’t come as a surprise but it is hands down the best way to improve at the game itself and Olaf specifically.
If you play enough you will reach a point where you don’t have to focus on your cooldowns and you will know your limits etc. When you reach this state you can put all your focus on the macro play which will win you more games in the end!
