What makes 
Olaf clear so fast?
Olafs passive gives him bonus attack speed based on missing health, now combine that with the fact that his 
Reckless Swing costs health while also having its cooldown reduced for every auto attack Olaf does and you've got an insanely powerful clear. Also Olafs 
Undertow cooldown can be reduced by picking up his axe, which can be thrown into the wall and immediately picked up this way.
Is it worth to take tower shots for a faster clear?
I've been asked this question a lot and my answer is no, it's not worth. In this season you have way to little time before your first buff spawns. Also as minions come to lane early, laners will be there too so its just too easy to punish an Olaf who walks up to a tower and takes a tower shot or two. The trade off is not worth it, especially considering that the clear is very fast already.
Which Runes are BEST for Olaf?
Considering Olaf has as very big attack speed steroid in his passive, going double 
Adaptive Force is by far the best choice combined with 
Health Scaling. Since Olaf runs 
Conqueror most of the times, going for 
Legend: Alacrity is a great options as well!
What spell is best to start?
As mentioned in the beginning of the guide, Olaf gets more attack speed the lower he is, so taking Reckless Swing level one is the best option, as it gets him to low health, while also dealing a lot of damage. Of course if we took Reckless Swing level one, the only option for level 2 is Undertow. On level 3 if you want to be safer from invades, taking 
Tough It Out is an option, but it does slow down the clear and I like to full clear with this champion, base buy items and look to fight on 
Scuttle Crab, so in my opinion going two points in Undertow and opting for the fastest possible first clear is the best choice.
Buying items before Scuttle Crab
As long as you finish the clear by 2:30 and base immediately, you will walk into river at 2:55, allowing you to fight any champion that starts it with item advantage. You can buy whatever items you want for 750g that you would have, but I personally recommend going for 
Long Sword and 
Ruby Crystal as they give you the best raw stats for a level 4 fight. Also you do have a free 
Smite still!
Keep in mind that this clear is done by 2:29 and its far from perfect. So there is definitely room for mistakes and taking it easy and still being on time to base and buy items before Scuttle Crab!
Important mechanics & Tips:
- Since your spells have really low cooldown, sometimes its better to just sit in place and spam them then trying to kite - look at the guide to see my movement
- Throwing you Undertow into the wall next to you, hitting the camp and immediately picking up the axe without having to walk to it is very important, and takes a little bit of practice
- If you are slower for whatever reason, you can still use your second Smite, base, buy items and be on Scuttle Crab in time with item advantage
