Elauria

You conjure a surging storm of negative energy in a 20ft. radius, 80 foot high cylinder. All creatures in the affected area must make a Constitution saving throw, taking 6d6 necrotic damage plus 6d6 force damage and receive a 2d4 penalty on all attack rolls and saving throws they make until the end of their next turn on a failure, and half as much damage and no additional penalties to rolls on a successful one.
