This is a item and ability build for drow ranger. It is aimed towards carrying your team completely. You will want to get the items listed as quickly as possible. After you have mask of madness you will want to jungle and get another level or two. After you have you boots built you will want to start trying to gank enemies and keep buying the items to complete the build. Remember to keep jungling where there isn't a team fight to attend, jungle. This build works 90 percent of the time for me.
