The issue is we have separate creatures in Horror affected by separate collections of these spells.

Whether this should be a net benefit or penalty is setting dependent so it should really be handled by unusual background (which should have a disadvantage form, but doesn't) rather than assigning a point value to class of being itself.

The only thing defined as a feature is being able to be hurt by those spells though.

No other aspects of spiritual magic were mentioned.
