This Yuan-ti has a head of long hair, and around her neck is a frill, not unlike a cobra's. She bears a long acid tipped spear and hisses in your direction, sending her minions forth to do her bidding. She seems to pulse with infinite power, both from spell and from some other unseen source. When your blades and spells strike her, without having disabled that mysterious power emanating from her altars, she seems completely impervious to every attack you throw at her. While you fruitlessly attempt to attack her, she calls down powerful Druidic magics.
