Enchanted Lullaby

Intro
The Enchanted Lullaby music box was bought by the party at Wending's Wonders for 100 gp. It was crafted by Agatha Skittlewise with the help of some friends.

Description
The small wooden box is decorated with carved detail. When opened, it plays a song which is so peaceful and soothing that it feels a little magical.

Effect
If any friendly creatures who can hear the music box regain hit points at the end of the short rest by spending one or more Hit Dice, each of those creatures regains an extra 1d6 hit points.
