Cobra Dragon
A cobra dragon is gloss black, with an orange underbelly. On either side of its neck is a large hood of skin that resembles that of a king cobra. Legend holds that certain king cobras of great age transform into cobra dragons.
Morbid Collectors Skull collecting is a favorite pastime of cobra dragons. Skulls of powerful monsters and rare creatures are highly prized. Favorite skulls include those of cave bears, dinosaurs, dragons, giants, and unicorns. Humanoid skulls are deemed interesting but of little value since they are so easily obtained. The offering of a rare skull as a gift when attempting to converse with a cobra dragon aids considerably in gaining the dragon’s favor.
Faithful Followers Due to its charisma, power, and cunning, a cobra dragon of adult age and beyond attracts a small number of intelligent creatures who search for a leader to serve. Goblins, lizardfolk and yuan-ti commonly are found in service of a cobra dragon.
A Cobra Dragon's Lair
Cobra dragons live in caves and underground caverns in tropical and subtropical environments. They dislike swamps. Like other dragons, a cobra dragon lays claim to an area of land surrounding its lair, ferociously driving off all other creatures. Intrusion by another cobra dragon is only tolerated during the spring mating season. The mating ritual involves the male and female entering non-injurious combat that results in a fiery display.
Lair Actions
On initiative count 20 (losing initiative ties), the dragon takes a lair action to cause one of the following effects; the dragon can't use the same effects two rounds in a row.
- Magma erupts from a point on the ground the dragon can see within 120 feet of it, creating a 20-foot high, 5-foot-radius geyser. Each creature in the geyser's area must make a DC 15 Dexterity saving throw, taking 21 (6d6) fire damamge on a failed save, or half as much damage on a successful one.
- The dragon creates a cloud of thick, billowing smoke as though it had cast the fog cloud spell. The smoke lasts until initiative count 20 on the next round.
Regional Effects
The region containing a legendary cobra dragon's lair is warped by the dragon's magic, which creates one or more of the following effects.
- Water sources within 1 mile of the lair are supernaturally warm and tainted by sulfur.
- Clouds of black smoke lightly obscure the land within 6 miles of the dragon's lair.
