Red dragons ranging from brilliant blood red to dull terracotta, powerfully built with heavy-jawed heads and thick muscular bodies
Mountain dragons are red in color, ranging from the brilliant blood red of a hatchling to the dull terracotta color of an ancient individual. These dragons are powerfully built, with heavy-jawed heads and thick muscular bodies, yet their necks are still long enough to give them the legendary flexibility of a true dragon.
They are cruel monsters, actively seeking to hunt, torment, kill and consume intelligent creatures. They are often said to prefer women and elves, but in truth a mountain dragon will attack almost any creature less powerful than itself.
They are intelligent and self-assured, but also impatient and overconfident. One will often plan strategies in advance and then choose one at random when facing unknown opponents, without regard to whether or not the strategy is likely to work. The sheer power of a mountain dragon is often the only reason one is still alive.
Mountain dragons are immune to normal fire, and suffer only half damage from magical fire.
