A basilisk is a reptilian monster that petrifies living creatures with a mere gaze. A basilisk usually has a dull brown body with a yellowish underbelly. Some specimens sport a short, curved horn atop the nose. An adult basilisk’s body grows to about 6 feet long, not including its tail, which can reach an additional length of 5 to 7 feet. The creature weighs about 300 pounds.
A basilisk relies on its gaze attack, biting only when opponents come within reach. Though it has eight legs, its slow metabolism renders it relatively sluggish, so it does not expend energy unnecessarily. Intruders who flee a basilisk rather than fight can expect, at best, a halfhearted pursuit. These creatures tend to spend most of their time lying in wait for prey, which includes small mammals, birds, reptiles, and similar creatures.

An abyssal greater basilisk’s natural weapons are treated as magic weapons for the purpose of overcoming damage reduction.
Smite Good (Su)
