Niffis

AC:DM Bestiary Description
''The eerily floating Niffis cast bizarre shadows across the sands. Strangely beautiful, these creatures are, unfortunately, also aggressive. Their form suggests an affinity for water, yet many of them congregate in deserts, basking in the harsh sun and balancing themselves with their lateral “wings.” It is thought the fine-grained Derethian sand may fulfill a function similar to water for the Niffis, a creature obviously saturated with alien and incomprehensible magic. Still, some rare Niffis do appear to seek out water, suggesting these creatures may once have had more humble and ordinary origins.

''While Niffis can cast spells, their preference appears to be for close combat, and their wildly whipping tentacles can cause great damage. Yet, as much as travelers dread seeing a Niffis’ form come floating across the dunes, something about this creature has caused more than a few people to stop and stare in awe -- sometimes to their regret.''
