If she picks up magic again, it seems like that's probably precisely the tiger-summoning ritual.
...It's the magician's own fault that he was so vague that she has no bloody idea what on earth she's not supposed to do.
@Seracila:
I mean, it's always been my assumption that, whatever the magician was
trying to do, he's just really bad at communicating and has truly utterly horrible people skills.
Though it's always possible he's just a straightforward evil sadist, of course! But that would be boring.
