Shards of the Celestial Chorus

Wondrous Item (Musical Instruments), rare (requires attunement)

Forged from ethereal hope and celestial harmony, this collection of crystalline shards resonates with a gentle glow that shifts colors depending on the reality around them. Each shard is attuned to a different aspect of music and sound, offering the wielder a variety of powerful effects.

When you attune to these shards, you create a musical instrument of your choice (e.g., flute, lute, harp, or drum) made from the shards themselves. This instrument can be used as a spellcasting focus for bard spells, and it has the following properties:

  1. Harmonic Burst: As a bonus action, you can play a short melody that sends a wave of inspiring sound in a 30-foot radius around you. All allies within range gain temporary hit points equal to your proficiency bonus.

  2. Disruption Melody: You can choose to play a dissonant note as a reaction when a creature within 60 feet makes an attack roll or casts a spell. The target of the attack or spell must make a Wisdom saving throw against your spell save DC. On a failed save, the attack or spell automatically misses or is countered, expending the effect. This ability can be used once per long rest.

  3. Echoing Recital: While you are holding and playing the instrument, you can cast the spell Mirror Image once per long rest without using a spell slot. When cast this way, the images are accompanied by a choral melody, which grants you advantage on the first saving throw you make within 1 minute of casting.

  4. Lullaby of Dreams: Once per long rest, you can perform a soothing melody for a duration of 10 minutes. All creatures within a 30-foot radius who hear it must succeed on a Wisdom saving throw or fall into a deep sleep, similar to the spell Sleep, with the additional effect that you can choose to awaken them at any time as a bonus action.

Each time you use one of these magical effects, the shards emit a soft light and a musical hum, which gradually intensifies with each use. If a shard is used three times in one day, it becomes temporarily dim, losing its magical effects until the next dawn. This encourages strategic use, making players think carefully about when to unleash the power of the celestial sounds.

Conditioned by the embrace of magic and the essence of music, these shards provide not only power but a delicate dance of strategy and inspiration in the heat of battle.
