If the darakhul spy is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

A darakhul in a prepared disguise has advantage on Charisma (Deception) checks made to pass as a living creature. While using this ability, it loses its Stench.

The darakhul spy deals an extra 7 (2d6) damage when it hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of the darakhul spy that isn’t incapacitated and the darakhul doesn’t have disadvantage on the attack roll.

Any creature that starts its turn within 5 feet of the darakhul must make a successful DC 13 Constitution saving throw or be poisoned until the start of its next turn. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the darakhul’s Stench for the next 24 hours. A darakhul using this ability can’t also benefit from Master of Disguise.

While in sunlight, the darakhul has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.

The darakhul and any ghouls within 30 feet of it have advantage on saving throws against effects that turn undead.
