@Hookshot: Which is exactly why she doesn't use her Semblance nearly as often as others do. It's dangerous because it can't distinguish targets, and it's very easy for her to affect an ally or a bystander if they get caught in it. With her allies, it's not as bad because their Aura protects them, and the effects go away after leaving the AOE. But civilians are a concern. However, what I meant by no Aura whatsoever was creatures who don't have any Aura to begin with; i.e., things without souls, such as plants and Grimm. In this sense, a human or faunus with their Aura depleted would still be affected negatively, but not with potential deadliness as a side effect.

I don't like that as much though. When you think about it, any offensive Semblance is capable of causing death or permanent damage; this Semblance is just a lot more blunt and direct about it. And as Mini said, maintaining the haze for that long (long enough to both deplete another person's Aura and then cause physical damage to the point where it escalates to physical deterioration) would cost a significant amount of Aura and stamina to Rosie herself.
