So I've been looking over Aberrant Mind, the spells it provides and sorcerer metamagic and I noticed that Careful Spell makes it that you can select creatures up to your Charisma modifier that don't have to make saving throws against the spell cast. So I was wondering does that mean an Aberrant Mind sorcerer could cast Evard's Tentacles with Careful spell and make it that they won't be harmed by Evard's tentacles?

Or would it just keep them from being restrained?
