Amulet of Dragonkind
Wondrous item, rare (requires attunement)
There are five different types of this amulet. Each has a gemstone set in the center.
While wearing this amulet, you gain resistance to one damage type. The gemstone determines the type of resistance.
Further, while wearing this amulet, you can use an action to fire a line that is 5 feet wide and 60 feet long. Each creature in that line must make a DC 15 Dexterity saving throw, taking 8d6 damage on a failed save, or half as much on a successful one. The gemstone in the amulet determines the type of damage. Once used, this property cannot be used until the next dawn.
