Senna Ability (LoL): Piercing Darkness

Senna shoots a bolt of piercing shadow through an ally or enemy. Enemies hit take 30 / 60 / 90 / 120 / 150 (+0.4 per bonus attack damage) physical damage. Allied champions hit are healed for 40 / 50 / 60 / 70 / 80 (+40% of ability power) (+0.3 per bonus attack damage) (+1.6 per 1 lethality) health.

Basic attacks reduce Piercing Darkness' cooldown by 1 second.
