Anasil is not naturally immune to death attacks and would have to roll vs her own power if it somehow got reflected. She has death ward cast on her currently or something similar, however I'd like to point out reflecting gaze attacks would not work since neither her stunning glance or death glance count as gaze attacks or even require her to have vision and/or eyes. The base power wasn't listed as being a gaze attack or anything like that and what it was modeled after wasn't either. She can just as easily use them through blindsight than anything else and they function vs targets that are blinded and unaware of her eyes as well. It just requires her to be able to directly target them and they have to be within range for her to activate it.
