Fire in the Hole! As an action, Crazy Pete can light a stick of dynamite and throw it at a point up to 60 feet away. Each creature within 5 feet of that point must make a DC 12 Dexterity saving throw, taking 3d6 bludgeoning damage on a failed save, or half as much damage on a successful one.

Bundle 'em Up. As an action Crazy Pete can bind sticks of dynamite together so they explode at the same time. Each additional stick increases the damage by 1d6 (to a maximum of 10d6) and the burst radius by 5 feet (to a maximum of 20 feet).
