Yowlis are primitive, muscular, 11' tall humanoids that haunt mountainous peaks and frigid wastes. While clearly avian (with feathered bodies, beaks, and oversized claws), they curiously possess mammalian sex characteristics. They can rotate their heads almost a full 360 degrees around, and are never Surprised.
Yowlis are fierce combatants. They are almost invisible in snowy conditions, and Surprise on a roll of 1-4 on 1d6. Three times per day, they can screech so terrifyingly that any non-yowli within a 50' radius flees in a random direction for 3d4 rounds on a failed Saving Throw Versus Energy. And their spittle (capable of being sprayed up to 15' away) is acidic, doing 1d10 damage on contact and an additional 1d8 damage per round for 1d6 rounds.
Their wings are non-functional, and only used in threat and mating displays.
Mutations: Increased Sense (Vision), Reflective Epidermis (Cold), Toxic Weapon (Spittle)
