Multiattack

The sand hag makes two claw attacks.

Claw

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage. If the target is a creature, it must make a successful DC 12 Constitution saving throw or gain one level of exhaustion.

Scouring Sirocco (Recharge 5-6)

The sand hag generates a blast of hot wind in a 30-foot line or a 15-foot cone. Creatures inside it take 14 (4d6) slashing damage plus 7 (2d6) fire damage and are blinded for 1 minute; a successful DC 14 Constitution saving throw halves the damage and negates the blindness. A blinded creature repeats the saving throw at the end of each of its turns, ending the effect on itself on a success. The affected area (line or cone) is heavily obscured until the end of the sand hag's next turn.

Change Shape

The hag polymorphs into a Small or Medium female humanoid, or back into her true form. Her statistics are the same in each form. Any equipment she is wearing or carrying isn't transformed. She reverts to her true form if she dies.
