At 9th level, and again at 15th level, your inner power manifests as innate magic. While only some dragons focus on casting spells, all gain some magical abilities as they grow in power. The ability you gain is based on your draconic lineage. Unless otherwise noted, you recover all uses of these abilities after a long rest.
You use your Charisma to determine the save DCs of your Dragon Magic abilities.
Spell Save DC = 8 + your proficiency bonus + your Charisma modifier
Spell attack modifier = your proficiency bonus + your Charisma modifier
You do not need to provide spell components for these spells; they are innate magical abilities, requiring only the action to cast them.
