Argent’s Pause

You halt and unconscious creatures timeline. The creature no longer must make death saving throws, but is not stabilized. Their body does not age for up to one minute, or until you lose concentration. 
When this spell ends, the creature resumes making death saving throws as normal.

Any healing, damage or additional spells cast on the creature resume it’s timeline, and the spell ends. 
The creature is considered petrified while under this spells effects, but weight does not change.
