Nah I was more imaginating it more like Sobek's ultimate in Smite :

"Sobek submerges himself, where he regens mana, is immune to crowd control and he slows all enemies. When Sobek emerges, he damages all enemies in the radius. Cancelling the ability decreases the damage." (official description, not really representative...)

In my head, it's like a, but without the damage and heal and slow and twice as long that end in a mini instant.
