Homebrew Fey Half-Dragon Species Details

Moonstone dragons are graceful and elegant creatures with opalescent scales and ruffs of emerald-green fur running down their chins, chests, backs, and tails. One horn arcs from the back of a moonstone dragon's skull and another at the tip of the nose; the two horns together form a shape that's reminiscent of a slender crescent moon. Moonstone dragons are playful and impetuous forces of mischief in their early years, but the best of them mature into wise teachers and storytellers who anchor Feywild communities. The worst of them are pompous and ill behaved, but even those remain gentle by nature and curious about all things—especially travelers from faraway places.

As a rule, moonstone dragons are not particularly interested in gold or copper, but they love silver, platinum, and mithral. They also cherish treasures whose value can't be easily quantified—a song sung from the heart, a lock of a loved one's hair, or a painting of a favorite place. A story of happy times fondly remembered is more precious to a moonstone dragon than a sack of gold.

Dream Breath Weapon

Your breath weapon sends creatures into a magical slumber. Roll 5d8; the total is how many hit points of creatures this spell can affect. Creatures within 20 feet of a point you choose within range are affected in ascending order of their current hit points (ignoring unconscious creatures).

Starting with the creature that has the lowest current hit points, each creature affected by this spell falls unconscious until the spell ends, the sleeper takes damage, or someone uses an action to shake or slap the sleeper awake. Subtract each creature's hit points from the total before moving on to the creature with the next lowest hit points. A creature's hit points must be equal to or less than the remaining total for that creature to be affected. After you use your breath weapon, you can’t use it again until you complete a long rest

Undead and creatures immune to being charmed aren't affected by this spell.
