MM Dungeon Nightmare

Nightmare
Nightmares are unicorns that have changed over time due to their contact with Malassa. Their coat has become black like onyx, their muzzles skeletal and tortured, and their clear eyes deep black. Their horn, once a symbol of fertility, is the receptacle and the physical embodiment of the nightmares which these creatures are cursed to see and feel.

The thundering gallop of a Nightmare generates waves of horror that spread and propagate terror among enemy ranks. The horn of a Nightmare, when retrieved after combat, is a precious artefact. Crafted, shaped, and transformed, equipped with a hilt or shaft, it can become a sword or lance that carries and transmits the same nightmares that the beast itself collects.
