You command up to three willing prone creatures of your choice that you can see within range to sleep. The spell ends for a target if it wakes up, such as through damage or being shaken awake as an action. If a target remains unconscious for the full duration, that target gains the benefit of a short rest, and it can’t benefit from this spell again until it finishes a long rest. The spell’s duration is one-fifth the time normally required for a short rest (for example, 12 minutes for a one-hour rest).

When you cast this spell using a spell slot of 4th level or higher, you can target one additional willing creature for each slot level above 3rd.
