This build is good for top and bottom. The item build is very expensive and I have never finished it. The key to Lee Sin is using his passive to get energy back otherwise you get drained after using two abilities and their actives.

Since they've nerfed the passive attack speed on Lee I added in a few speed marks to counter the nerf. Since there is an innate armor penetration buff for dominion it's an acceptable loss.

The armor penetration marks and quintessences are pretty standard for all attack damage/speed champions.

The armor seals just the added protection at the start of the game when physical damage champions are very lethal.

The scaling magic resist glyphs are just a counter to the mid/late game ability power champions.
