Flashbang

Surprise Explosive. You can use an action to activate and throw this item to a point within 45ft. of you. When it detonates, the item flashes brightly and a loud bang erupts from it. Each creature within 10ft. of the point of detonation must make a Constitution saving throw (DC 13).On a failed save, they take 3d8 Thunder damage and are Deafened and Blinded until the end of their next turn. On a successful save, they take half damage and are not Deafened or Blinded. A creature made of inorganic material (such as stone, crystal, or metal) has disadvantage on this saving throw.
