She appears to take whatever she's carrying with her when she transforms as long as she's holding it, such as her sword and mask. If the relic is small enough to tie to her belt or put in a pocket, I don't see why she can't transform it with her.

Beyond that, she was strong enough to break a solid wooden baulistrade as a raven. I think she'd be strong enough to carry a relic that can be carried by humans with her as a bird.
