Black Breath

You extend your hand toward a creature you can see within range and project a puff of noxious gas from your mouth area (on a nazgul or the witch king of angmar, this would be the empty head region) is released into a 10ft cone. The creature must succeed on a Constitution saving throw or take 1d8 necrotic damage, 1d12 on a failed save.

This spell's damage increases by 1d8 / 1d12 when you reach 5th level (2d8 / 2d12), 11th level (3d8 / 3d12), and 17th level (4d8 / 4d12).
