Whilst attuned to this magical item the wearer has advantage on saving throws against magical effects and is immune to the charmed condition
In addition, once per day, the wearer can use an action to choose to recover an amount of expended spell slots. The spell slots can have a combined level that is equal to or less than 3 (if you have access this level of spell). Once used you can’t use this feature again until you finish a long rest. As an example, when you recover up to three levels worth of spell slots, you can recover either one 3rd-level slot or three 1st-level slots or some other combination.
However each time the amulet is used in this way the wearer must roll a d20, on a 1-4 the amulet shatters and no longer functions.
