Special Traits


  • Multiattack. The mavka makes two slam attacks.

With burnt and blackened skin, burnt twigs for hair, and clawed hands and feet that resemble burnt and twisted roots, mavkas seem scorched and even frail. Pupil-less red eyes gleam in their eye sockets with a hellish green flame.


These twisted dryads have been turned into vampiric monstrosities by undead warlocks and vampiric experiments.

Death Riders. All mavkas ride nightmare mounts as fearsome raiders, often snatching victims up into the saddle, never to be seen again. They despise and trample foot soldiers as peasants unworthy of attention.

Hag Killers. Mavkas are the mortal enemies of red hags, who call these undead horrors “greenbanes.”

Mavkas were once three dryad sisters. The dryads and their trees were killed and then raised as powerful undead. Warlocks bonded the new undead with nightmares instead of trees to complete their corruption.

These three sisters have since spawned many more such undead fey whom pursue their own ends, destroying vampires, laying waste to whole villages, and seeking power. The mavkas occasionally refer to one another as “sister-wives.”
