Magic Items

An Instrument of the Bards is superior to an ordinary instrument in every way. Seven types of these instruments exist, each named after a bard college. The Instruments of the Bards table lists the spells common to all instruments, as well as the spells specific to each one and its rarity. 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 play the instrument to cast one of its spells. 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.

To attune to this vial, you must place a few drops of your blood into it. The vial can't be opened while your attunement to it lasts. If your attunement to the vial ends, the contained blood turns to ash. You can use the vial as a spellcasting focus for your spells while wearing or holding it, and you gain a bonus to spell attack rolls and to the saving throw DCs of your sorcerer spells. The bonus is determined by the vial's rarity.

In addition, when you roll any Hit Dice to recover hit points while you are carrying the vial, you can regain 5 sorcery points. This property of the vial can't be used again until the next dawn.
