Fires an arrow at the target unit, that deals fixamount dmg and applies damage over time debuff with fix damage intervalls. If target dies with the debuff hero is healed for amount% of fixamount damage(not the Dot!). Edit: oh i forgot to say that the debuff needs to be can be dispellable. Example level 1 tooltip: Fires an arrow at the target unit, dealing 150 dmg and haunting it for additional 35 dmg every 3sec over 30sec. If target dies whilst being affected by this spell, the hero is healed for 20% of the damage dealt by the shot. If it already does exist, just point me in the direction.
