This build is basically a stronger version of the BORK build, with an insane power-spike in the mid game. This build scales into the late game really well and the early game isn't that bad except for a bit of lost attack speed that you would have using the BORK build.

Warlords and Fervor and both great masteries to take, so feel free to use those. I like bringing Stormraiders Surge because it is very easy to proc with how much damage you have in this build. It makes you sticky and compliments your passive very nicely. Still, I take this mastery because I like it, feel free to use whatever you like.

The runes for this build have a bit less damage for a bit more attack speed. This is to make up for the lost attack speed you would have if you were to build bork instead of BT first item.

I recommend maxing Q first, but you can try whatever you want.
