Survival in New Vance

Bonus Action. You unleash a wide, arcing sweep with your modified plasma cutter. Every creature within a 15-foot cone originating from you must make a Dexterity saving throw (DC 21). On a failed save, a target takes 8d8 radiant damage and is blinded until the end of its next turn as superheated plasma scorches its sensory organs. On a successful save, the target takes half damage and is not blinded. Shamblers have disadvantage on their saving throw. Range: 15-foot cone. Duration: Instantaneous.
