General Feat (Prerequisite: Level 8+, Medusa species)
Your Petrifying Gaze has come into its own. If a creature that has the Restrained or Paralyzed condition as a result of one of your spells or your Medusa’s Gift trait fails a saving throw to end the effect by 5 or more, you can choose to turn that creature to stone. Any magical effects causing the creature to have the Restrained or Paralyzed condition end, and the creature has the Petrified condition for 1 minute. You must concentrate to maintain the effect. If you lose your Concentration, the Petrified condition ends.
If you maintain your Concentration on the effect for the entire possible duration, the target is Petrified until the condition is ended by Greater Restoration or similar magic.
