You target one creature or object within 30 feet and create antimatter in the same space. A targeted creature makes a Dexterity saving throw or takes 10d8 force damage and until it receives healing equal to the initial damage, it cannot benefit from rest as the antimatter continues to interact with the creature’s matter over time. A creature reduced to 0 hit points is obliterated, leaving behind nothing but atomic particles, along with anything it was wearing or carrying (except indestructible items).
