Black Breathe (Recharge 5–6). The village breathes black smoke in a 90-ft.-line that is 10 ft. wide. Creatures in the line must make a DC 17 Constitution saving throw, taking 16 (10d8) necrotic damage and its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest or until lesser restoration or similar magic is used. The target dies if this effect reduces its hit point maximum to 0.

On a successful save, they take half that damage and their hit point maximum isn't reduced.
