Campfire Lullaby

You sing a gentle and soothing lullaby that affects all creatures within 30 feet of you who can hear it. Each creature must make a wisdom saving throw; a creature can choose to fail this throw. On a failed saving throw, the creature falls asleep. If the creature sleeps the full duration of the spell, the creature gains the benefit of a long rest, even if it has already completed one within the last 24 hours. To gain the beneficial effects of this spell, the recipients must focus their undivided attention on you while you cast the spell. If they do not pay attention, they do not gain the benefits of a long rest, but they do not fall asleep either. Sleeping creatures awaken if they take damage, or if a creature uses their action to shake the sleeping creature awake. A creature that is immune to sleep is not affected by this spell. A creature can only benefit from this song once every 5 days.
