Gargoyles are monstrous hunters made of elemental stone. They use their resemblance to decorative statues to hide in plain sight in cities during the day and descend upon unlucky pedestrians at night. Their most common form is that of a horned humanoid with bat-like wings, but individual gargoyles show a great deal of variation, with some appearing more or less humanoid and others resembling no known creature. A gargoyle's features are not flxed; city-dwelling gargoyles who remain in the same locale long enough slowly morph, day by day, to match the style of the local architecture. These patient monsters can stay disguised for long stretches of time as they patiently await an opportunity to strike.
