Zox Clammersham has created a small yet unstable item made of a metal alloy and has powerful explosive materials inside.  This item is disk shaped, fitting in the palm of the average human hand. 

As an action, a creature can throw it like a frisbee at a point up to 50 feet away.  Any creature or object within 25 feet of that point must make a DC 15 Dexterity saving throw, taking 8d6 bludgeoning damage, 2d6 fire damage, and is also blinded for 1 round by the bright color display on a failed save, or half as much damage on a successful one.  

The explosion makes a loud noise that can be heard up to 300 feet away and displays bright lights of random color when detonating (player rolls a 1d6 - see color chart).  

Zox Big Boom is very unstable.  Each time Zox Big Boom is handled by a creature, they must make a Dex saving throw (DC 10) or have the item explode taking 8d6 bludgeoning damage and 2d6 fire damage.  Damage rules for any creature within 25 feet of the creature that mishandled the item are the same as if it was thrown.
