Abilties:

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.
Frenzy: Volibear's repeated attacks grant him additional attack speed. Once Volibear has repeatedly attacked four 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 (Ultimate): 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.


SO I'm wondering if this is gonna be another Mana free champion just by looking at Frenzy.I'm not sure if it gives him a chance to rapidly attack 4 times and if successful bite the foe(Like Xins triple talon strike) or if it has a passive that increase his attack speed with each hit for a duration then and after every 4th attack, it is proc'd and can bite the foe.
