Once per long rest as an action. You can Transform into one of many Dragon types at a young age. You choose between of  Metallic, Chromatic, Gem, Solar, and Luna (you can't change types). This transformation can't be dispelled by other spells or magic effects. You also gain Resistance to the type of damage that the Dragon of your choice haves, you also can read and speak Draconic.
