Volibear Ability (LoL): Thundering Smash

Volibear gains 12 / 16 / 20 / 24 / 28% movement speed, doubled towards enemy champions for the next 4 seconds. While active, Volibear's next attack deals 10 / 30 / 50 / 70 / 90 (+1.2 per bonus attack damage) physical damage and stuns the target for 1 second. Volibear becomes enraged if an enemy immobilizes him before he stuns a target, ending the ability early but refreshing its cooldown.
