A black corona surrounds a creature you can see within range, stealing time from it and causing it to age. Spectral, black sand flakes away from the corona around the target and settles into the hourglass you are holding. The target must make a Constitution saving throw. On a failed save, the target takes 1d6 necrotic damage, and it ages one hour. On a successful save, the target takes half the damage and doesn’t age one hour.    As part of casting this spell or as a bonus action on a subsequent turn but before your next long rest, you can consume this stolen hour of time. Alternatively, you can gift the time to a friendly creature you can see within range. As a bonus action at any point before your next long rest, that creature can consume the stolen time.    A creature that consumes the stolen hour of time can expend Hit Dice to regain hit points as if it had completed a short rest. The creature doesn’t gain any other benefits of a short rest.
