To true sight effects, Sarabisia looks to be whatever current shape she is using, and her alignment appears to be whatever she currently wishes it to detect as. Any attempt to read her mind is likely to end badly.
She is immune to practically all spells and effects, including many which might actually be beneficial to her. She cannot suppress this immunity. (Whilst her immunities include magical force attacks and electrical attacks, she does have the power to swat away with her hands or other body parts such effects which strike her if she feels so inclined.) She posesses limited shape-shifting abilities, being able to adjust her shape at will from that of her natural form of a seeringly beautiful woman with leathery wings, so long as her form remains that of an adult female of human, alu-fiend, aasimar, or succubus nature. (Although her eyes always remain the same).
She has an absolute timeline; no matter who tries it, attempts to travel back in time and rewrite history where she has been directly involved always fail, and she herself cannot travel in time. She is 'invisible' to divinations about the future. Such magic always predicts a course of events as if she does not interfere in them, even though she may end up doing so and substantially changing them - although any 'destinies' changed by her will revert to their normal course once her interaction with them is removed, unless seven generations have passed in the meantime.
Sarabisia is bad news for surprises, tending to take off guard anyone who tries to catch her flatfooted.
When hunting someone, Sarabisia tends to leave a trail of lilies behind her, a quirk which very few people survive to report.
