Taliesin's Horror

You transform yourself in to a creature of the darkest dread and horror. Dark energy starts pulsing around you, suffocating each creature in range except you. Each creature within range must make a Constitution saving throw or take 1d4 necrotic damage and move 5 feet away from you.

This spell’s necrotic damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), 17th level (4d4).
