As an action, a Medusa can use its petrifying gaze on any creature within 30 feet as long as they can see each other. You must be able to look into the eyes of that creature. The creature must make a DC 14 Constitution saving throw while you are not incapacitated. If the saving throw fails by 5 or more, the creature is instantly petrified. Otherwise, a creature that fails the save begins to turn to stone and is restrained. The restrained creature must repeat the saving throw at the end of its next turn, becoming petrified on a failure or ending the effect on success. The petrification lasts until the creature is freed by the greater restoration spell or other magic.

Creatures not composed of flesh and unable to see using eyes, such as plants, oozes, spirits, constructs, and certain celestial beings, as well as those with immunity to petrification or being restrained, are unaffected by your petrifying gaze.

If you see your own image reflected in a polished surface within 30 feet of yourself and in dim light or brighter, you are affected by your own gaze. If your eyes are seen through something that obscures them, such as thick fog or within a murky mirror, your gaze does not affect those who look into your eyes.

Your Constitution score increases by 2, and your choice of either Dexterity or Charisma increases by 1.

You are able to see in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern colors in darkness, only shades of gray.

You have tough, scaly skin. When you aren’t wearing armor, your AC is 13 + your Dexterity modifier. You can use your natural armor to determine your AC if the armor you wear would leave you with a lower AC. A shield’s benefits apply as normal while you use your natural armor.

Your snake hair is a natural weapon, which you can use to make an unarmed strike. If you hit, you deal piercing damage equal to 1d6+STR. That creature must make a DC 10 Constitution Saving Throw, taking 2d4 poison damage on a failed save, and half as much damage on a successful one.

Medusae speak Common, and one extra language of your choice. Typically this is a language native to whatever race the medusa was before their curse transformed them into what they are now, such as Elvish or Draconic.
