This build rocks for me, I will sometimes swap items in and out of my build to compensate for whom ever Im up against.

This build usually takes squishies with full or half life to dead in about one shot to them, so try to focus on squishies first.

The Ruines are Critical Damage and Cool Down Reduction.
I chose crit damage over crit ratio is because I can build crit ratio in game, but I cant build crit damage. So the Crit damage is a better priority over crit ratio.

The total crit damage from ruines is 41% + Masteries 10% = 51% critical damage applied to your total attack damage, this ontop of your infinity edge makes squishies and even tanks focusing on you.

I use last whisper and blood thrister in there if im being too heavy focus on.

Plz try out my build and let me know what ya think.
