Ultimate Rage of the Destructive Lord

You summon a small flaming bull Avatar with a black storm cloud hovering above it, the bull runs in one direction for 200ft before being automatically dispelled, furthermore if the bull hits a piece of cover bigger than itself it will be automatically dispelled. Rage of the Distant Bull and Rage of the Great Raijin must've been cast before casting this spell. The bull gets larger as it runs, its maximum size being large instead of medium, and as it runs it spreads a line of dark clouds behind it. When the spell is dispelled the clouds rain down single target chain lightning bolts on anything within its radius doing 3d8 + [Your Spell Casting Bonus] damage. The Bull itself does more damage the further it goes, and explodes when dispelled. If a target is hit by a direct lightning strike, inflict them with a Paralysis debuff.
