Scimitar

Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage plus 7 (2d6) necrotic damage.

Dust Devil

The al-aeshma creates a swirling dust devil centered on a point it can see within 120 feet of it. The dust devil appears in the shape of a cylinder that is 30 feet tall with a 5-foot radius. Each creature in the area and each creature that enters the area for the first time on a turn or starts its turn there must succeed on a DC 17 Strength saving throw or be restrained. While restrained, a creature takes 7 (2d6) slashing damage and 7 (2d6) necrotic damage at the start of each of the al-aeshma's turns. A creature, including a restrained creature, can take an action to free the restrained creature by succeeding on a DC 17 Strength check.
