Spellcasting (Psionics). The dragon casts one of the following spells, requiring no spell components and using Intelligence as the spellcasting ability (spell save DC 16):
At will: dancing lights, guidance
1/day each: hypnotic pattern, lesser restoration
Multiattack. The dragon makes one Bite attack and two Claw attacks.
Bite. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit:14 (2d10 + 3) piercing damage plus 4 (1d8) radiant damage.
Claw. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit:6 (1d6 + 3) slashing damage.
Scintillating Breath (Recharge 5–6). The dragon exhales a burst of brilliant radiance in a 30-foot cone. Each creature in that area must make a DC 15 Constitution saving throw, taking 27 (6d8) radiant damage on a failed save, or half as much damage on a successful one. The dragon then gains 10 temporary hit points by absorbing a portion of the radiant energy.
Shimmering with radiant energy and brimming with life, crystal dragons enjoy an innate psionic connection to the Positive Plane that suffuses their bodies as well as their personalities with light. Though they prefer to live in desolate, frigid regions, many of them are among the friendliest of dragonkind, nurturing and optimistic.
