Kil’groth dashes forward, slowing foes’ mobility by 25/30/35/40/45/50% for 1.5 seconds while causing 100/125/150/175/200/225 (+0.65 AD) physical damage to them. When it hits an enemy hero, the cooldown is lowered by 4 seconds.

Every normal attack made over the next 4 seconds that the ability is active will deal an additional 50/85/120/155/190/225 (+0.25 additional AD) magic damage. Kil’groth’s HP is restored by 45 (+0.2 AD) for each target he hits. When Kil’groth strikes a hero, he restores 150% of their HP.
