As an action, you sing a lullaby to a creature that you can touch or see within 10 meters. The creature must make a Will saving throw. If the creature is a construct or an undead, can’t hear you, or is immune to being charmed, the spell has no effect on it.

On a failure, it becomes tired and delirious as its speed is reduced by 2 meters, it can’t take reactions, and it has disadvantage on skill checks until the end of its next turn.

This spell ends for a creature if it takes damage or someone uses an action to shake or slap it awake. Additionally, the creature can repeat the saving throw if it hears an extraordinarily loud noise such as the thunderwave spell, ending the effect on itself on a success.
