Dulcimer of Scribing

This musical instrument has 3 charges. While playing it you can use an action to expend 1 charge from the instrument and write a magical message on a nonmagical object or surface that you can see within 30 feet of you. The message can be up to 6 words long and is written in a language you know. Bards can scribe an additional 7 words and choose to make the message glow faintly, allowing it to be seen in nonmagical darkness. Casting Dispel Magic on the message erases it. Otherwise the message fades after 24
