Miasma of Kurn

9th-level necromancy

Casting Time: 1 reaction

Range: Self (15 ft. radius sphere)

Components: V

Duration: Concentration, up to 1 minute

You release a dark, miasmic, magical shroud of dark vapors that surround you in a 15 ft. radius sphere. For the duration, creatures you designate cannot see through this miasma, and anytime a creature that you haven’t designated enters this area or starts its turn within the radius, they must make a Constitution saving throw. On a failure, the creature takes 10d8 necrotic damage and gains 1 level of exhaustion.

Creatures with the exhausted condition subtract their number of levels of exhaustion from the saving throw.
