The Gorgon has an ability called Petrifying Breath which reads as below:
Petrifying Breath (Recharge 5-6): The gorgon exhales petrifying gas in a 30-foot cone. Each creature in that area must succeed on a DC 13 Constitution saving throw. On a failed save, a target begins to turn to stone and is Restrained. The Restrained target must repeat the saving throw at the end of its next turn. On a success, the effect ends on the target. On a failure, the target is Petrified until freed by the Greater Restoration spell or other magic.
Now if the target fails both of the CON saves they are petrified. What if they have only failed their first save but have yet to make their second? Is there any spell or ability that can remove the condition turning the target to stone?
