Breath Weapons (Recharge 5-6)

The dragon uses one of the following breath weapons.

Gravitic Breath

The dragon exhales localized gravity in a 30-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 17 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 dragon's breath weapon recharges.

Stellar Breath

The dragon exhales star fire in a 30-foot cone. Each creature in that area must make a DC 17 Dexterity saving throw, taking 21 (6d6) fire damage and 21 (6d6) radiant damage on a failed save, or half as much damage on a successful one.
