Blue Dragon
Vain and territorial, blue dragons soar through the skies over deserts, preying on caravans and plundering herds and settlements in the verdant lands beyond the desert's reach. These dragons can also be found in dry steppes, searing badlands, and rocky coasts. They guard their territories against all potential competitors, especially brass dragons.
A blue dragon is recognized by its dramatic frilled ears and the massive ridged horn atop its blunt head. Rows of spikes extend back from its nostrils to line its brow, and cluster on its jutting lower jaw.
A blue dragon's scales vary in color from an iridescent azure to a deep indigo, polished to a glossy finish by the desert sands. As the dragon ages, its ·scales become thicker and harder, and its hide hums and crackles with static electricity. These effects intensify when the dragon is angry or about to attack, giving off an odor of ozone and dusty air.

Vain and Deadly
A blue dragon will not stand for any remark or insinuation that it is weak or inferior, taking great pleasure in lording its power over humanoids and other lesser creatures.
A blue dragon is a patient and methodical combatant. When fighting on its own terms, it turns combat into an extended affair of hours or even days, attacking from a distance with volleys of lightning, then flying well out of harm's reach as it waits to attack again.
Desert Predators
Though they sometimes eat cacti and other desert plants to sate their great hunger, blue dragons are carnivores. They prefer to dine on herd animals, cooking those creatures with their lightning breath before gorging themselves. Their dining habits make blue dragons an enormous threat to desert caravans and nomadic tribes, which become convenient collections of food and treasure to a dragon's eye.
When it hunts, a blue dragon buries itself in the desert sand so that only the horn on its nose pokes above the surface, appearing to be an outcropping of stone. When prey draws near, the dragon rises up, sand pouring from its wings like an avalanche as it attacks.
Overlords and Minions
Blue dragons covet valuable and talented creatures whose service reinforces their sense of superiority. Bards, sages, artists, wizards, and assassins can become valuable agents for a blue dragon, which rewards loyal service handsomely.
A blue dragon keeps its lair secret and well protected, and even its most trusted servants are rarely allowed within. It encourages ankhegs, giant scorpions, and other creatures of the desert to dwell near its lair for additional security. Older blue dragons sometimes attract air elementals and other creatures to serve them.
Hoarders of Gems
Though blue dragons collect anything that looks valuable, they are especially fond of gems. Considering blue to be the most noble and beautiful of colors, they covet sapphires, favoring jewelry and magic items adorned with those gems.
A blue dragon buries its most valuable treasures deep in the sand, while scattering a few less valuable trinkets in plainer sight over hidden sinkholes to punish and eliminate would-be thieves.
A Blue Dragon's Lair
Blue dragons make their lairs in barren places, using' their lightning breath and their burrowing ability to carve out crystallized caverns and tunnels beneath the sands.
Thunderstorms rage around a legendary blue dragon's lair, and narrow tubes lined with glassy sand ventilate the lair, all the while avoiding the deadly sinkholes that are the dragon's first line of defense.
A blue dragon will collapse the caverns that make up its lair if that lair is invaded. The dragon then burrows out, leaving its attackers to be crushed and suffocated. When it returns later, it collects its possessions- along with the wealth of the dead intruders.
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 effect two rounds in a row:
- Part of the ceiling collapses above one creature that the dragon can see within 120 feet of it. The creature must succeed on a DC 15 Dexterity saving throw or take 10 (3d6) bludgeoning damage and be knocked prone and buried. The buried target is restrained and unable to breathe or stand up. A creature can take an action to make a DC 10 Strength check, ending the buried state on a success.
- A cloud of sand swirls about in a 20-foot-radius sphere centered on a point the dragon can see within 120 feet of it. The cloud spreads around corners. Each creature in the cloud must succeed on a DC ls''constitution saving throw or be blinded for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
- Lightning arcs, forming a 5-foot-wide line between two of the lair's solid surfaces that the dragon can see. They must be within 120 feet of the dragon and 120 feet of each other. Each creature in that line must succeed on a DC 15 Dexterity saving throw or take 10 (3d6) lightning damage.
Reginal Effects
The region containing a legendary blue dragon's lair is warped by the dragon's magic, which creates one or more of the following effects:
- Thunderstorms rage within 6 miles of the lair.
- Dust devils scour the land within 6 miles of the lair. A dust devil has the statistics of an air elemental, but it can't fly, has a speed of 50 feet, and has an Intelligence and Charisma of 1 (-5).
- Hidden sinkholes form in and around the dragon's lair. A sinkhole can be spotted from a safe distance with a successful DC 20 Wisdom (Perception) check. Otherwise, the first creature to step on the thin crust covering the sinkhole must succeed on a DC 15 Dexterity saving throw or fall 1d6 x 10 feet into the sinkhole.
If the dragon dies, the dust devils disappear immediately, and the thunderstorms abate within 1d10 days. Any sinkholes remain where they are.
