Canaith Mandolin

You can play the instrument while casting a spell
that causes any of its targets to be charmed on a
failed saving throw, thereby imposing disadvan-
tage on the save. This effect applies only if the
spell has a somatic or a material component.
The Canaith mandolin can be used to cast each
of the following spells once per day:
cure wounds (3rd level), dispel magic, fly, invisibility, levitate, protection from energy
(lightning only) and protection from evil and good.
