Sniper

Kardel Sharpeye the Sniper is a ranged agility hard carry who excels at dealing heavy damage at an incredible range. His third ability, Take Aim, allows him to deal high DPS at a safe distance, and avoiding damage as he is relatively frail. He also excels at harassing enemies due to his second ability, Headshot, which gives him a chance to do extra damage and mini-stun, and his first ability, Shrapnel, which slows and deals damage over time in an area. This makes him especially efficient in middle lane. And with sufficient rune control, Sniper can make a deadly hero to be laning against especially if you are a melee Hero, such as Pudge or Bloodseeker, given that the correct precautions are made. He also scales quite nicely into late game, being able to slow and/or mini-stun fleeing heroes so they can be ganked. Though he is a rather frail hero, his potential in the hands of a good player and team is high. Due to the relatively simple nature of his gameplay, Sniper is recommended for New to Intermediate players.
