Can't shoot what they can't see! Watch this.

[She takes a deep breath and holds out one hand. When she exhales, a long a steady stream of smoke and mist is produced and large quantities at that until the surrounding streets and alleyways are obscured with fog while the path ahead of them is clear for them to move. Iona gestures to Claude to move ahead while she follows.]

Neat, huh? Best part is, you can just explain that it was a smoke bomb and not magic!
