Black dragons are entities of disease and rot, corrupting the world from their swampy homes.
Physically, black dragons are most distinguished by their horns, which protrude from the sides of their heads and wrap around, projecting forward. A large frill adorns the upper part of the neck. They smell like rotting vegetation and foul water, or like the powerful acid they can breathe.
- Breath Weapon: Black dragons breathe a line of corrosive acid.
Black dragons first appeared in the OD&D White Box.
