Inspiring Performer

You know your way around an instrument and with a song can rally those to your cause. You gain the following benefits:

• Increase your Charisma score by 1, to a maximum of 20.
• You can spend 10 minutes inspiring your companions, shoring up their resolve to fight via musical performance. When you do so, choose up to six friendly creatures (which can include yourself) within 30 feet of you who can see or hear you and who can understand you. Each creature can gain temporary hit points equal to your level + your Charisma modifier. A creature can't gain temporary hit points from this feat again until it has finished a short or long rest.
