      "This weapon is decorated with dragon heads, claws, wings, scales, or Draconic letters. When it steeps in a dragon's hoard, it absorbs the energy of the dragon's breath weapon and deals damage of that type with its special properties.",
      "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 {=bonusWeapon} bonus to attack and damage rolls made using the weapon. On a hit, the weapon deals an extra {@damage 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 {@damage 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."
