Blessed Rest

You implore your god (or source of your power) to grant you, and your allies the incredible blessing of rest. Up to nine willing creatures (including you, if you wish) of your choice that you can see within range fall unconscious for the spell’s duration. The spell ends on a target early if it takes damage or someone uses an action to shake or slap it awake. If a target remains unconscious for the full duration, that target gains the benefit of a long rest, and it can’t be affected by this spell again until it finishes a long rest.

Every time you cast this spell, and the benefit is granted, you roll 1d20-1. The result of the roll determines how many days must pass before you can use the spell again.
