You tap into the malevolent power of Black Fatalis, unleashing an abyssal force that engulfs the area around you. The spell has the following effects:

1. Darkened Vortex: Each creature in the 60-foot cone starting from you must make a Constitution saving throw. On a failed save, a creature takes 10d8 necrotic damage, and its maximum hit points are reduced by an amount equal to the damage taken. On a successful save, the creature takes half damage, and its maximum hit points are not reduced.

2. Eclipse of Shadows: The darkness created by the spell extinguishes all non-magical light sources within the radius, plunging the area into magical darkness for an hour.

3. Abyssal Desolation: The ground within the radius becomes cursed, and the area is considered difficult terrain for the next hour. Any creature besides you that starts its turn in the area takes 4d8 necrotic damage.
