Volibear Update concept

Chosen of the Storm Volibear periodically regenerates 30% maximum health over 6 seconds when below 30% maximum health while within a cloud.

Turbulent Updraft ACTIVE: Volibear gains bonus movement speed for the next 4 seconds, doubled when moving towards a nearby visible enemy champion within 1800 units of him knocking minions aside. While active Volibear's next basic attack deals bonus physical damage and flings his target over and behind himself. Turbulent Updraft resets Volibear's autoattack timer, and pulls/pushes clouds within 500 units along within him.

Frenzy->Thundering Frenzy PASSIVE: Volibear's AA's grant bonus attack speed for 4 seconds, stacking up to 3 times and generate a stationary cloud (with a 100 unit radius) every 2 AA. At 3 stacks, Volibear gains the ability to cast Lightning Frenzy. Active: For the next 6 seconds, Volibear's basic attacks deal the same damage as bonus magic damage that bounces to up to 10 nearby clouds (within 500 units of each other). Enemies monsters and towers within 400 units of clouds, take damage, increased by 25% for every cloud they are within range of.

Roaring Downburst ACTIVE: Volibear roars forcefully pulling down the air from the sky dealing magic damage to all nearby enemies and knocks nearby clouds back to 500 units slowing and knocking down and grounding enemies that pass through them for 3 seconds. Minions and monsters will be feared. Has no cast time while Turbulent Updraft is active and will not interrupt it.

Supercell Warrior ACTIVE: Volibear rises up and draws in clouds within 3000 units gaining size, bonus HP, and AA range before slamming down and dealing magic damage within 500 units. Airborn targets are suspended for 0.75 sec and take bonus damage. For the next 12 sec. Volibear's AA create a cones of hail storms that last 1 sec that slow enemies. The Supercell Warrior's AoE, Volibear's size, and AA range all all increased by the number of clouds pulled in.

In terms of Lore I feel like Volibear can be both a mystic seer vastayn polar bear Ursine and a Demi-god. Think of it as Volibear picks the most suitable host to inhabit out of the Ursine the one that reflects his attributes the best and this time it was a seer. I guess that kinda makes Volibear like an aspect, but its more like the the Ursine seer is channeling Volibears power, they kinda share the reigns unlike pantheon who gets completely taken over and unlike Leona, Diana, and Zoe who merely use the Aspects power, the Seer and the Demi-god have become one, like the Avatar idk.
