Uncommon Wondrous Item
Surprise Explosive. You can activate and throw this item to a point within 45ft. of you. When it detonates, the item flashes brightly and a loud bang emanates from it. Each creature within 10ft. of the flashbang has to 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 only 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.
