While attuned to the harp, you can use an action to learn whether any creature you can see within 120 feet is affected by a spell or other ongoing magical effect. You learn the general nature of each effect, but not its source, exact duration, or hidden conditions. This property does not identify nonmagical conditions.

As an action, expend 1 to 10 charges and choose up to one creature per charge that you can hear within 120 feet. Choose one ongoing spell or magical effect affecting each chosen creature; a chosen creature can instead contribute one magical curse affecting it. Each chosen creature must make a Charisma saving throw against your spell save DC, or DC 20 if you have none. A creature can voluntarily fail. If fewer than two creatures fail, the song has no effect and expended charges are wasted. Otherwise, arrange the affected creatures in any order and transfer each selected effect to the next creature in that order, with the last creature's effect going to the first. The effect keeps its original duration, concentration status, and other rules; the harp does not end or duplicate it. An effect that cannot affect its new bearer, or a curse that explicitly cannot be transferred, stays with its original bearer. The DM determines whether an effect is transferable. This property cannot transfer artifacts, attunement, disease, injury, or nonmagical conditions.

As an action, expend 3 charges and choose two creatures you can hear within 120 feet, one of which must be willing. Transfer one ongoing spell or magical effect, including a transferable magical curse, from one creature to the other. The effect retains its duration and rules. An unwilling creature can make a Charisma saving throw against your spell save DC, or DC 20 if you have none, to resist receiving the effect. If the effect cannot affect its new bearer, it remains with the original creature. The DM determines whether an effect or curse is transferable.

As an action, expend 2 charges and choose up to six creatures you can hear within 120 feet. Each chosen creature gains temporary hit points equal to 2d8 plus your proficiency bonus. A creature can gain these temporary hit points only once per use of this property.
