after some consideration i decided that unyelding and block are even better then i thought. expecially against low damaging attacks and damage over time.
unyelding works for both physical and magic damage and the reduction should apply after the armor/mr mitigation so the actual damage reduction is really HUGE early game, expecially against opponents that will harass you frequently with low damaging attacks.
like a teemo for example: i think the reduction applies to both the physical and magical portion of the attack and of course for every tic of the damage over time, so getting 2 points into unyelding and 1 into block means 5 damage reduction for the physical portion of the autoattack, 2 for the initial magic damage and 2 for every tic of magic damage thereafter for another 8 damage reduction (toxic shot's poison applies every second for 4 seconds).
the total reduction is 15 and the difference is really HUGE.

@ Zave Thanks for the feedback! I am open to suggestions, always. I will for sure try it out, and it seems like you know what ur saying, so thanks again. I will play a bit, rethink/redo my masteries.

in my opinion you should rethink about putting (wasting) 3 mastery points into "legendary armor".
just in case you did not notice the +5% is only for your "bonus" armor and mr. so it doesn't boost your innate stats, just the ones you get from items, runes, masteries and skills.
at level 1 your basic armor is 20 and your bonus armor is 17.69 for a total of 37.69 rounded up to 38 which gives you 28% phys damage reduction.
a +5% increase will increase your armor to 38.57 rounded up to 39 (so you get +1 armor) which gives you 28% phys damage reduction (which is the same value you get with 38 armor, so no actual change at all at level 1).
for magic resist is even worse because you start with only +6.35 bonus mr and you won't even see a +1 increase on your stats.

what of late game with all the tanky items?
well, at level 18, with your most tanky build you get +120 armor from items (if you go ninja tabi), +17.69 from runes/masteries and +60 when you activate your ultimate.
your innate armor is 71 and adding all up you reach 209 without ult and 269 with, so your phys damage reduction is 66% without ult and 73% with.
with legendary armor you reach 216/279 for a reduction of 68%/74%.
and the change is even less noticeable for magic res (i don't feel like doing the math).

in my opinion you should be much better off investing into "unyelding" and "block" for a better early game against AD or into "safeguard" and "reinforced armor" for a much better late game.

@ STEPONLEGOS I max out my Q first to give myself time to be able to not worry about how much health I have when Eing. I have tried both ways, and maxing Q just works a bit better for me. Also maxing your Q will allow you to lane better as your pokes will hurt more.

Hey, nice work on the guide, but I've been wondering, why does everyone max the undertow first instead of wreckless swing. I think that q costs more mana when you level it, and when you wanna fight or heal up, its so mana hungry. E is manaless and if you build health, then chunking their hp won't affect you as much. Qing with w to heal is very miniscule and costs a lot of mana to do often. Why level q and not e? Thanks!

The Build is AWESOME! but i think ghost is better than flash on olaf... but nice job it is a very good build keep up the good work :D

@TheEinherjar Thanks! Im glad to hear that you're doing well!

Hi there!

I tried your guide a couple of times now and I must say that I have been quite successful with it up to now! I'll stick to it and come back later to vote!

Cheers!

Add item build for situational and other options. Also some laning tips/playing.

Besides that ok guide
