[Patch 1.0.0.130: Volibear] General Discussion

League of Legends v1.0.0.130
Volibear, the Thunder’s Roar
Rolling Thunder: Volibear drops to all fours and runs faster if chasing an enemy champion. The first enemy he attacks is knocked into the air and flung behind Volibear.
Frenzy: Volibear's repeated attacks grant him additional attack speed. Once Volibear has repeatedly attacked three times, he can perform a vicious bite on his target.
Majestic Roar: Volibear lets out a powerful roar that damages and slows enemies. Minions and monsters are feared as well.
Thunder Claws: Volibear channels the power of the storm causing his attacks to blast his targets with lightning that bounces to other nearby enemies.
Chosen of the Storm (passive): Volibear heals rapidly for a few seconds when his health drops to a critical level.
