Bite

Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 5) piercing damage plus 9 (2d8) necrotic damage, and the target's Strength score is reduced by 1d4. The target dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest. If the target is a Humanoid, it must succeed on a DC 17 Constitution saving throw or contract the darakhul fever disease (see the Darakhul Fever sidebar).

Gravedust

The ghoul projects a 30-foot cone of grave dust. Each creature in the area must succeed on a DC 17 Dexterity saving throw or take 13 (3d8) necrotic damage. If a creature is a Humanoid, it must also succeed on a DC 17 Constitution saving throw or contract the darakhul fever disease (see the Darakhul Fever sidebar).

Whirlwind (Dust Form Only; Recharge 5-6)

The ghoul creates a whirlwind of bones and teeth in a 20-foot cube originating from it. Each creature in that area must make a DC 17 Dexterity saving throw. On a failure, a creature takes 55 (10d10) slashing damage, and its Strength score is reduced by 1d6. The creature dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest. On a success, a creature takes half the damage and its Strength score isn't reduced.
