Prerequisite: Requires succeeding the Wisdom saving throw in a Nightmare encounter and rolling The Heretic.
Nightmare. You utter a forbidden word of power, inflicting great suffering upon those that would defy you.
As a bonus action, you can immobilize your foe with a sacrilegious word. Choose a creature within 15 feet of you. The creature must succeed on a DC 13 Constitution saving throw or take 2d6 necrotic damage and fall prone as they vomit up blood. On a success, the creature takes half damage and doesn’t fall prone.
You can use this ability once before refreshing it in town using Performing Sacred Rites or Religious Service Downtime actions.
At Higher Levels. The attack deals an extra 1d6 necrotic damage and the ability DC increases by 2 when you reach 5th level, 10th level, 15th level, and 20th level.
