Armor > HP at Seals

AD > Arp Quints at Lee Sin (AD-ratios^^)

BTW: You could also get Hextech Gunblade instead of Bloodthirster, because it gives you way more usefull stats.

And a wall of text is pretty bad, use Searz awesome looking guide template from the forum/build & guide discussion.

oh, and early Boots?(after first back)

BTW: You should still get 1 defence item, or you are dead even before you can do your combo. Maybe Force of Nature instead of Phantom Dancer? It has also movement speed on it.

With the mobility in this build, combined with his Q, you should be able to stay in melee range consistantly. Like I said it's more of a melee carry/assassin build... not a tanky DPS build. Think talon.

I wouldn't ever grab a Phantom Dancer/Youmuu's on Lee Sin, he just doesn't gain much from attack speed/crit even if you are going for a full DPS build. (which by the way I wouldn't recommend as any melee that builds glass cannon like that will just die instantly)

Thanks, I will when I get a chance!

Hmmm. I like it, it helped me a lot.

But maybe try to make it more attractive.
Maybe add some pictures and icons. Or try formatting it.
