That's what I would have done

Cuz it could still find a way to kill the daughters when they're not looking. Also coral can be very naive and stupid at times

I don't think that's how it works like maybe she could word the spell to remove Orca's spell

But orca might've guessed coral would have done what she did and had gotten an Animus at some point. It's actually a very plain loophole that orca could've seen coming at some point. Or she just thought a different Animus could possibly enchant the statue so she put a line in where the first spell couldn't get overidded. This is a lot of assumptions, plz don't get mad

yeah, I'm just putting stuff out there

There's a lot of questioning in this fandom

Questions are the superior method of everything
