Rebecca can summon spectral imitations of anything she's read, so long as she can recall it precisely. These imitations aren't sentient, nor are they defensively strong, but they're powerful. It doesn't work if she's reading it off as she summons, so it must be something she's studied beforehand. She can summon up to three of these imitations. Anymore and her own life-force starts to drain, resulting in eventual loss of consciousness or even death.
