When you say her gift can replace the target's senses what does that mean exactly? Can she cause them to go blind/deaf, does she create false images and sounds?

Currently, just the former, and she's not aware of it yet. Once she learns to cast illusion spells, she'd be able to make a target see, hear, or otherwise sense almost anything she wants without the target's actual senses getting in the way. It'll only reach its true potential if she learns how to create those illusions in the first place, though.
