Another note, I used straight armor pen for my olaf, yi, and tryn runes. But with Black Cleaver, Starks fervor, and dragon strike, I figured lategame armor reduction is better. Idk quite yet. AS is good for getting madreds razors procs for early farming. And lategame for all the onhit affects this build has.

Good you mentioned that, cuz I looked at my actual build ingame, and I do use archaic knowledge. But good points on not rushing merc treads and philosopher's stone over clarity. I will be editing this guide as I go. THANK YOU!

Drop a point into Archaic Knowledge if you plan on getting Madred's Bloodrazor imo. Also, ArP has a longer lasting benefit than AS. If you're using movement speed quints then I don't see much of a reason to rush merc treads of madred's razor. level 1 boots with movement speed quints and jarvan's gap closer is sufficient imo. Also grabbing Philosopher's stone early can be a quick alternative to having to bring clarity. This frees up a summoner skill for something like ghost or smite (buff security).

It's good to see a guide focused at TT though.
