Bite

Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 5) plus 1d4 Strength damage, and the target must succeed on a DC 17 Constitution saving throw or be paralyzed for 1d4 + 1 rounds. If the target creature is humanoid, it must succeed on a second DC 19 Constitution saving throw or contract darakhul fever.

Gravedust

A bonepowder ghoul can project a 40-ft. cone of grave dust. All targets within the area must make a DC 19 Dexterity saving throw to avoid taking 4d8 necrotic damage, and must make a second DC 17 Constitution saving throw to avoid being infected with darakhul fever.

Whirlwind (Recharge 5-6)

A bonepowder ghoul can generate a whirlwind of bones and teeth. All creatures within a 20-foot cube take 66 (12d10) slashing damage and are drained of 1d6 Strength; a successful DC 17 Dexterity saving throw reduces damage to half and negates the Strength loss. The whirlwind dissipates after one round.
