Potion of Resuscitation

Potion, very rare This potion appears to be an empty vial, but it actually contains a foul-smelling gas. When it is held under the nose of a creature and unsealed, the gas escapes. If the creature is unconscious, stunned, or incapacitated, those conditions end immediately, assuming the creature is at 1 hit point or higher. If a creature that isn't suffering any of those conditions smells the potion, it must make a DC 10 Constitution saving throw or be stunned until the start of its next turn.
