Vertigo is a wicked cobrasaur sorceress from another dimension who was released from banishment when the Great Meteor collided with the Urth. She functions as an 18th-level mage specializing in alteration magic. She dwells in a place of insanity located in multiple dimensions and accessed through a conduit located at an ancient stone circle.
Combat: In combat, Vertigo attacks with two claws, a deadly poison-laden bite, and a powerful tail slash. If she scores a successful bite, the opponent must save vs. poison (type E). A successful save results in 20 hp damage; a failed save means instant, painful death.
In addition to her mage spell powers, she also has a number of deadly spell-like powers accessable at will. They are a scorpion sting, gaze, and acid spittle.
For the scorpion sting, she can transform her tail into an adamantine spike with which to strike opponents. The tail hits for 3-30 hp damage. A Dexterity check allows an opponent to dive out of the way, but prevents him from being able to have initiative in the following round.
Her gaze can either hypnotize or petrify. For hypnosis, the range is 50', and she can affect up to 10 individuals, who must save vs. spells at -4. The petrification has a range of 20' and can affect up to three individuals whose save vs. petrification is at -3.
Up to 10 times per day, Vertigo can spit a globule of poisonous green acid up to 100' affecting an area with a radius of 20'. This acid causes 15d10 hp damage. A successful save vs. breath weapon will reduce the damage by half.
Vertigo can also teleport at will, with no error.
She is completely immune to acid, poison, and magical fire. Normal fire and lightning do only half damage.
Habitat/Society: Vertigo's worshippers consist of sorcerors and witches. When the Great Meteor hit the planet and the continents were re-arranged, some ancient stone circles still remained, and it is near one of these ancient magical vorteces that Vertigo founded her Urthly temple.
The evil cobrasaur sorceress then opened a planar conduit within the circle connecting her directly to her extradimensional "Temple of Insanity."
