You create a magical campfire with a color of your choosing. This campfire cannot be extinguished unless willed by the caster. After the 8 hours, it is automatically extinguished. 

Soft music can be heard originating from the campfire, bolstering the casters allies who spend a long rest near it. Basking in the campfire's warmth grants a Bardic Inspiration Dice equal to the caster's ability for the next 24 hours. If the Bardic Inspiration is used within the 24 hours, it is expended and cannot be used again. The Bardic Inspiration is also expended if it is not used within the 24 hours. 

The caster is able to cast Bardic Inspiration on any creature that has used a Bardic Inspiration in this way, but as per the description of Bardic Inspiration, the caster cannot stack them.
