Sand Walk. The dragon can move across sand without needing to make an ability check. Additionally, difficult terrain composed of sand doesn't cost it extra movement.

Multiattack. The dragon makes three attacks: one with its bite and two with its claws.

Bite. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 21 (3d10 + 5) piercing damage

Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 19 (4d6 + 5) slashing damage.

Sand Breath (Recharge 5–6). The dragon exhales blinding hot sand in a 30­-foot line that is 5 feet wide. Each creature in that line must make a DC 13 Dexterity saving throw, taking 49 (11d8) piercing damage on a failed save and the creature becomes blinded until the end of the dragon's next turn, or half as much damage on a successful one and the creature is not blinded.
