Sniper is a very easy hero to learn how to play DotA with. This build is best suited for mid lane but he works in the safe lane as well. (Top for Dire, bottom for Radiant.) I focus the build around Sniper's Take Aim passive for safety reasons and early kills / pushing. Remember to keep an eye on those with Gem of True Sight, Dust of Appearance, and Sentry Wards if building a Shadow Blade. The build itself is really simple and easy to understand, let me know how it plays out for you though! Enjoy!
