Void Dragon Wyrmling

Chill of the Void. Creatures with resistance to cold damage don't have resistance to the cold damage dealt by the Void dragon. A creature with immunity to cold damage is still immune to the dragon's cold damage.

Expert Void Traveler. The Void dragon doesn't require air, food, drink, sleep, or ambient pressure. While traveling in the Void, the dragon magically glides on solar winds, covering immense distances in short times.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) piercing damage plus 3 (1d6) cold damage.

Breath Weapons (Recharge 5-6). The dragon uses one of the following breath weapons.

Gravitic Breath. The dragon exhales localized gravity in a 15-foot cube, originating from the dragon. When a creature ends a fall in the cube, it takes 1d10 bludgeoning damage for every 10 feet it fell, to a maximum of 20d10. A creature that enters the cube for the first time on a turn or starts its turn there must make a DC 13 Dexterity saving throw. On a failure, the creature is restrained. On a success, the creature's speed is halved as long as it remains in the cube. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. The cube lasts until the start of the dragon's next turn.

Stellar Breath. The dragon exhales star fire in a 15-foot cone. Each creature in that area must make a DC 13 Dexterity saving throw, taking 10 (3d6) fire damage and 10 (3d6) radiant damage on a failed save, or half as much damage on a successful one.

Void Twist. The dragon adds 2 to its AC against one attack that would hit it, as it twists reality to open a small rift in space to protect itself. To do so, the dragon must be able to see the attacker.
