Any smaller pieces of debris that get past Iriceli, provided any of those things are flammable, still don't last long enough to actually hit anyone, as Viola joins in on the defense and targets anything that can burn in order to destroy it and remove it as any sort of threat. She's much more-accustomed to going on the offense and would honestly rather be doing so still, but most of the others here are more-experienced than her, it would be a waste for any of them to be preoccupied with this instead.
