Her hair looks so nice, I’d have a hard time not wanting to touch it, even knowing it’s venomous poisonous. Maybe rather than a stone gaze, her gaze inflicts a variant of Command, compelling you to touch her hair. I’ve been afflicted. Additionally: Maybe she can’t control it, and she hates that about herself; she can never form meaningful relationships without inadvertently poisoning everyone she grows attached to. She’s a sympathetic character and the adventure revolves around trying to find a way to lift her curse without falling victim to it yourselves.
