With the aid of Arepo, you have unlocked your dormant talent for the arts that permeate the natural world.
You gain an innate understanding of how to play the lyre. This instrument is your arepoan instrument. You have proficiency with the chosen instrument and can summon a spectral version of it as a bonus action, which functions as a spellcasting focus for any spells you can cast. It vanishes if it ever leaves your person, and can be dismissed at any time, no action required.
Awoken Muse. When you use your arepoan instrument as a spellcasting focus, it can also replace verbal components. If you replace verbal components of a spell that either deals damage or restores hit points, you may then add your Charisma modifier to the damage roll or the total amount of hit points restored.
Spotlight. As an action, you can perform your favourite tune using your arepoan instrument. When you do so, one creature within 60 feet of you regains 1 hit point, and a moving 10-foot cylinder of light centered on the target appears for 1 minute. All friendly creatures within the cylinder are immune to being charmed or frightened, and any such effects immediately end on them. The spotlight itself is bright, beating sunlight with a scent of seawater, and any creatures moving in the area leave sandy imprints. Once you use this boon, you can't do so again until you finish a short rest, unless you expend a spell slot of 1st level or higher.
