Dracolisks are surmised to be the result of the mating of a black dragon and a basilisk, though rumours persist of the existence of other sorts. These fearsome creatures most resemble their draconic sires, being armoured with thick black scales and having the horns and sharp toothed maws of their forebears; they also have six powerful clawed limbs and two large wings. If a dracolisk speaks a language at all, it is usually draconic, though it may be that some can understand other languages.

Although capable of flight, dracolisks are limited to only short durations, ten or twenty minutes at the most, before they have to rest, so they principally use this form of movement to swoop down upon or escape from foes. In physical combat, dracolisks bite for 3d4 damage and strike for 1d6 damage with their two forelimbs. However, they are more likely to use their breath weapon or gaze attack before entering melee.
