Sniper

Position 2 · Mid

Key Points

Dota's idol. As his name suggests, he has the longest attack range.
An area slow with his 1st ability, extreme range with his 3rd, and an ult to finish enemies off. All of them are one of a kind.
The enemy will definitely try to kill Sniper first, so positioning matters, and so does having abilities or items that you or your teammates can use to protect you.
