Whenever you roll a 20 on your attack roll with this weapon, each creature of your choice within 5 feet of the target takes 5 damage of the type dealt by the dragon's breath weapon.

You gain a +3 bonus to attack and damage rolls made using the weapon. On a hit, the weapon deals an extra 3d6 damage of the type dealt by the dragon's breath weapon.

As an action, you can unleash a 60-foot cone of destructive energy from the weapon. Each creature in that area must make a DC 18 Dexterity saving throw, taking 12d6 damage of the type dealt by the dragon's breath weapon on a failed save, or half as much damage on a successful one. Once this action is used, it can't be used again until the next dawn.

Proficiency with a Hand Crossbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
