Crystal Dragon Wyrmling

Hatchlings have glossy white scales that become more and more translucent with age. By the time they reach adulthood, these scales become luminescent in moonlight. In the full light of the day they glow with a dazzling, almost unbearable brilliance.

Fun-loving and mischievous, crystal dragons tend to be irresponsible rulers. For the daily running of their domains, these dragons rely on their vassals to keep things going. They establish domains in the cold, open mountaintop reaches, building castles out of snow and ice. They leave these castles open to the sky, for they love to watch the stars on clear, cold nights. The white dragon clans consider crystal dragons to be nothing more than prey, so the two types are almost always in conflict.

Like other benevolent dragons, the crystal dragons prefer to talk rather than fight. Even without special abilities, they can be charming and engaging to an extreme. Gems and metal ores are their foods of choice. They mate with willing partners whenever they want, as desire and need move them. It has also been known for crystal dragons to adopt white dragon hatchlings.

A Crystal Dragon’s Lair

Crystal dragons lair in snow-covered mountains, dwelling in giant castles built for their pleasure.

The crystal dragons spends much of their time out ensuring tormenting frost giants and expanding their mountaintop castles. For a crystal dragon, the integrity of its castle is everything, without its castle complex, the crystal dragon is nothing.

Throughout the castle complex, the dragon keeps frozen giants and ice sculptures as trophies and monuments to its greatness. The halls nearest the front will occasionally house white dragon wyrmlings that the crystal dragon has adopted. 

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:

• The castle walls refract the light stored in the ice beneath the lair, casting a bright rainbow across everything in the castle. Each creature must make a Constitution saving throw, the DC equals 25 - 1 for each 5 feet of distance between the creature and the dragon, minimum DC 15. On a failed save the creature is blinded until the end of its next turn, and that creature may make a DC 15 Constitution saving throw at the start of its next turn, ended the effect on a successful save.
• The entire castle begins to radiate a chilling mist from the walls and floors. Each creature in the lair must make a DC 15 Constitution saving throw, taking 9 (2d8) cold damage on a failed save.
• The mountain's snowstorms pass over the castle, causing each creature in the lair except for the crystal dragon to become blinded until the start of the dragon's next turn.

Regional Effects

The region containing a legendary crystal 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 cold and tainted by salts that are various colors.
• The sunlight within 6 miles of the lair shines more brightly than usual, as if through a crystal magnifying lens. Moderate and mild weather conditions do not block direct sunlight in this area.
• The bottoms of clear water pools within 1 mile of the dragon’s lair form portals to the Para-Elemental Plane of Ice, allowing creatures of elemental ice into the world to dwell nearby.

If the dragon dies, these effects fade over the course of 1d10 days.
