Astral regeneration

You create a localized time loop that refreshes a creature’s body as if they had completed a long rest.

• Target gains all benefits of a long rest (HP, spell slots, features, hit dice).
• Exhaustion is reduced by 1 level.
• However, the strain of forcing this time loop comes at a cost: the target takes one level of exhaustion after 24 hours if they do not take a proper long rest before then.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature per slot above 4th.
