the Jester
Legend
Henry said:I think you have rightly discerned you set a bad precedent here, but if you want to play it by the book, the only solution is to say that her particular amulet is somehow special; i.e., it had an unknown power come to the fore, and that power is either now spent or is used up for x number of days.
Or just tell your players you made a mistake, and in the future you'll be ruling differently should the occasion arise. You might want to run with Henry's idea, though, since it spices up an otherwise pretty 'standard' item.
