Let her play an Elf, or even a High Elf, with the Scholar calling (Lore tradition). Tell her to describe each of her uses of Elven-skill (and later, of Words of Command) as genuine "spells", at least in the eyes of others. She can even take Gleam of Wrath to add a bit of dramatic effect in combat!
Still not 'magical' enough? Then same as above, but let her learn any spell you deem appropriate from the 5e PHB instead of Crafts, treating her Craft slots as if they were spell slots, and her Scholar levels as if they were Warlock levels to determine the level of those spell slots, and the number of spells known. (For example, a 5th-level Scholar would have 3 spell slots, each of 3rd level, and know 6 spells.)
Spell slots are recovered at the end of short rests, just like Crafts. Let her also learn a number of cantrips equal to her proficiency bonus, if you wish. That should do the trick, and kind of
preserve balance as well
It is not our part to master all the tides of the world, but to do what is in us for the succour of those years wherein we are set, uprooting the evil in the fields that we know, so that those who live after may have clean earth to till.
