Ashen Prowler

Ashen Prowler
This man-sized hound appears to be made of molten rock.
Ashen prowlers are vile, dog-like monsters native to regions where the elemental planes of Earth and Fire bleed into one another. They are heat-loving creatures, and when found on the Material Plane it is typically in magma chambers or other scorching hot environments. Fire heals them rather than harms them, and ashen prowlers take advantage of this by ensuring that they catch each other in their breath weapons when battling in tandem.
Although ashen prowlers do not need to eat, their malevolence is such that they delight in the incinerating of flesh and the crunch of bones in their jaws. Ashen prowlers are only dimly intelligent, but that intelligence is directed mainly towards vengeance. A creature that escapes or drives off a pack of ashen prowlers is likely to find itself hunted for days as the creatures seek to get their revenge. This single-mindedness makes them popular as guard beasts with salamanders and other evil elementals, but efreeti and shaitans typically find them too chaotic and unreliable to work with.
An ashen prowler stands four feet high at the shoulder and weighs nearly 500 pounds due to its rocky composition. They are social creatures that reproduce asexually when exposed to the magical energies of particularly potent lava fields—as such, these places are guarded ferociously by ashen prowlers and those that seek to use them.
