Thresh Ability (LoL): Death Sentence

Thresh throws his scythe, dealing 80/120/160/200/240 (+50% of ability power) magic damage to the first unit hit and dragging them towards him for 1.5 seconds.
Additionally, he may reactivate the ability to leap to his chained enemy.
If Thresh hits a target, Death Sentence's cooldown is reduced by 3 seconds.
