Carry. You are basically made of paper without mana shield, keep it on at all times by rightclicking the ability after leveling it. This hero essentially cannot play the game without good farming habits, stack camps and kill them with split shot and mystic snake. Mystic Snake does more damage the more it bounces, so do not target the enemy you want to take the most damage. Farm for like 20 minutes, yell at your teammates if you die.
