You summon the aspect of the void to unmake life. Choose a point within range; a 30-foot-radius zone. Utter stillness opens, swallowing thought and light. When a creature enters the area or starts its turn there, it must make a Wisdom saving throw:   On a failed save, the creature takes 12d10 shadow damage and cannot take reactions until the end of its next turn.   On a successful save, it takes half damage.   In addition, creatures reduced to 0 HP in this area leave behind no body, only a lingering black silhouette that fades in 1 minute.   The area is considered an anti-magic zone for illusion and enchantment spells of 6th level or lower.
