Dark creeper

The dark creepers were a race of humanoids dwelling in the Underdark. They were natural rogues with powers of stealth and shadow. They were one of the two subraces of the dark ones.

Description
Although humanoid in form, dark creepers were stunted in built, being small and slight. Unusually, they had unguligrade legs (similar to a goat's), ending in small black hooves in place of feet. These hooves were soft, making no sound on stone. A dark creeper's skin was pallid, and it had a large nose, sinister-looking eyes, and bushy eyebrows. They only ever wore black, shrouding themselves all over in cloaks, wraps and turbans or hoods.

Powers
Thrice a day, a dark creeper could envelop itself in cloak of shadows, concealing it from view even in bright light, aiding its defense. This darkness was magical, so a foe needed the ability to see in magical darkness to penetrate it.

A dark creeper could utilize all its acute senses—hearing and smell as well as sight—to discern its surroundings and locate beings. Even in absolute darkness, it had perfect sight out to 60 feet (18.3 meters).

However, when caught in daylight (natural or magical), a dark creeper was badly demoralized in all ways.

A dark creeper also had an extraordinary ability to evade harm.

Personality
The dark creepers hated light of any kind, and would assault any being who carried a source of illumination, whether a lantern, a torch, or magic. They did not harass those who passed without the aid of an artificial light source.

Combat
Dark creepers were craven creatures, but highly skilled in stealth and in ambush. They usually surprised and picked off their foes from the shadows. They were natural backstabbers, most dangerous when making a sneak attack from flanking or surprise. Dark creepers fought in total darkness wherever possible, and beat a hasty retreat if they lost the upper hand.

Society
Dark creepers were led into ambush and combat by dark stalkers, the leaders of the dark ones.

Dark ones spoke their own tongue. They seemed to comprehend Undercommon, but no one ever heard them utter it.

Relations
The dark ones were an enigmatic people, even to other races in the Underdark. They usually only came into contact with outsiders when they stole some item from others or defended their lairs from their foes.
