Doss Lute
Wondrous item, uncommon (requires attunement by a bard)
An instrument of the bards is an exquisite example of its kind, superior to an ordinary instrument in every way. Seven types of these instruments exist, each named after a legendary bard college. A creature that attempts to play the instrument without being attuned to it must succeed on a DC 15 Wisdom saving throw or take 2d4 psychic damage.
You can use an action to play the instrument and cast one of its spells: Fly, Invisibility, Levitate, Protection from Evil and Good, Animal Friendship, Protection from Energy (fire only), Protection from Poison. Once the instrument has been used to cast a spell, it can’t be used to cast that spell again until the next dawn. The spells use your spellcasting ability and spell save DC.
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 disadvantage on the save. This effect applies only if the spell has a somatic or a material component.
