Nicknamemy plz

Just because you're not getting boots of speed on an ARAM guide doesn't mean you have to base your entire guide around it.
Your tank busting build has no Botrk which wouldn't be a massive problem if half of your entire build wasn't based around armor pen.
Double Brutalizer rly??
Your build on Ravenous Hydra is the wrong order (is that even possible?), not to mention the fact that all you have to do to not lose health on ARAM is not get caught out early game.
Phantom dancer/Shiv is essential and not including it just to make your ARAM Master yi arpen guide more original is just stupid

No boots of movement, no Statikk Shiv...no dice.

There is so much wrong with this guide I don't even want to get into it....but I will cause I'm that bored.

-Flat armor seals PLS
-Masteries 21/9/0 there is no reason to have 25 points in offense.
-The health regen mastery in defense is useless on most champs, especially Yi. Put the 9 points in health and armor.
-No Botrk in the anti-tank build? really?
-No boots is idiotic especially when you don't even mention zephyr as a replacement for them.
-Your runes in the guide itself don't match the ones in the cheatsheet.
-Rush 3 ****ing regen beads? the ****....
-Great idea let's NOT build static shiv on the one map that the passive will actually proc on their entire team almost every single time!

Why are you even making a howling abyss guide....Pretty sure the only way to play howling abyss without playing ARAM is through a custom game, and people just **** around in those anyway. If this is an ARAM guide, well congrats now 1 out every hundred games people will have a ****ty build to follow while playing superpro ARAM and get all dem pentas!

I'll work on the code as time goes on. I just wanted to get this out there. I didn't see the point in arcane knowledge. Wasn't intentional. As you can see I just wanted to get this out there initially so I'll continue to make changes to it as time goes on.

Personally I just see too many people rushing zeals and basically ruining Yi's early game burst and it drives me nuts so I wanted to get a guide out there. Appreciate the feedback.

poor yi

Ok, so Theres a couple things here you need to look at.
Firstly, your masteries/runes. I understand taking 4%cooldown in the offense tree. What I don't understand is the point in Arcane Knowledge . Yi has literally no magic damage, making this useless. If you're gonna put 25 points in offense masteries (though Id stick to 21 as it lets me put 9 in defense) then you should swap Arcane Knowledge with Frenzy (the mastery, not the volibear passive that shows up here for some reason -_-).

Seal of Armor is very powerful in terms of defense early. Not saying its a must, but its worth looking at.

EDIT: You actually cant even get Arcane Knowledge without first putting 4 points into Blast , so yeah.

Second: you need to finish your skill level up chart. It looks sloppy if You just leave it at level 6.

third: you should use some code to make your guide look better. an example is writing things like "master yi" as " Master Yi" to do this you just write it with brackets like:
Needs a little work.
