[Jack O'All Trades]

Notably this is a setting where illusions involve (potentially) everyone's magical participation and everyone can magically disbelieve. It doesn't take much stretching to imagine a sort of weak form of Aid or a powerful version of Illusion is what is ultimately at work here. In fact you could make this sort of "divine enchantment" have a weakness to (mass?) disbelief to differentiate it further from regular enchantment.
