Musician
Instrument Training
You gain proficiency with three Musical Instruments of your choice.
Encouraging Song
As you finish a short or long rest, you can play a song on a Musical Instrument with which you have proficiency.
This will give 1 free reroll (must take the reroll) on D20 Tests to allies who hear the song. The number of allies you can affect in this way equals your proficiency bonus.
This benefit is lost when you the allies finish a short or long rest.
