Hi. It is my second build. I don't like to write much so it will be short explanation.

So after we have Bloodthirster we can buy Last Whisper or Infinity Edge. It depends on how much dmg you want. Personally i prefer LW instead of IE.
Last choice is between Frozen Mallet or Guardian Angel. First option gives us good burst of life and slow for opponent and second nice resistance and revive. Last item depends on enemy team.

Well this is all. If you have any question, just write it in comments.
