Patient Predator. An adult cave drake is between ten and fifteen feet long, with a thin, whip-like tail that nearly doubles its overall length. Its scales are dull and colored to match the surrounding stone. A cave drake hunts by lying in wait for prey to pass, often hanging from a wall or ceiling, before ambushing with its blinding venom. The drake then tracks the blinded creature as it flees, using a keen sense of smell and the creature's disorientation to follow it. A cave drake will follow prey patiently for miles, unless its quarry wanders into the territory of another cave drake.
