Gem Gaze [>] (emotion, fear, mental, primal) The stygira holds aloft a gem and gazes into the mind of a creature within 30 feet, infusing the creature's thoughts with visions of the creature's own dead body slowly petrifying. The creature must succeed at a DC 25 Will save or become frightened 1 (frightened 2 on a critical failure).

Stone Curse (curse, primal, transmutation) Wounds dealt by the stygira's claws leave the flesh bleached of color and turn the blood that runs from them dark gray. Each time a creature is damaged by the stygira's claw Strike, it must succeed at a DC 25 Fortitude save or become permanently slowed 1 (slowed 2 on a critical failure) as its flesh stiffens like stone. If a creature is reduced to 0 Hit Points from the stygira's claw Strike and fails the saving throw against stone curse, it is petrified. A creature that spends 8 hours in direct sunlight can attempt a new saving throw to remove the effects of stone curse, even if it has been petrified.
