Hard to say. Some don't think it's a separate power. That the same black poison liquid that makes up them just is a trait of it. Like some think it's not a negation per say. It's just like an area of effect range. That any close can't use their power. Remember Eve whom at least was connected to the leviathans. She unplugged Castiel over miles of town.
