Blasting Stone (Lesser)

When this pebble hits a creature or a hard surface, it explodes with a deafening bang. A blasting stone deals the listed sonic damage and sonic splash damage, and each creature within 10 feet of the space in which the stone exploded must succeed at a Fortitude saving throw with the listed DC or be Deafened until the end of its next turn. Many types of blasting stones grant an item bonus to attack rolls.

The bomb deals 1d4 sonic damage and 1 sonic splash damage, and the DC is 17.
