|Winged Dire Corby|
Wingless corbies are the norm, but reports occasionally surface of dire corbies with wings. Whether these specimens are naturally born throwbacks to that remote time when all corbies possessed the power of flight, the offspring of unholy unions with other winged creatures of the dark depths—such as cloakers, bats, or demons—or the product of magical experimentation (such as drow fleshwarping) is unknown. Winged corbies usually inhabit vast subterranean caverns that give them room to fly, but have been reported above ground as well, stealthily winging through nighttime skies. A winged corby has its climb speed replaced with a fly speed of 40 feet (average maneuverability), and it has the Fly skill (+5) instead of Acrobatics.
