This spell draws out the ancient nature within your blood, allowing you to assume the form of any dragon-type creature of challenge 10 or less. You assume the hit points and Hit Dice of the new form. When you revert to your normal form, you return to the number of hit points you had before you transformed. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn’t reduce your normal form to 0 hit points, you aren’t knocked unconscious. You retain the benefits of any features from your class, race, or other source and can use them, provided that your new form is physically capable of doing so. You can speak only if the dragon can normally speak. When you transform, you choose whether your equipment falls to the ground, merges into the new form, or is worn by it. Worn equipment functions normally, but equipment doesn’t change shape or size to match the new form. Any equipment that the new form can’t wear must either fall to the ground or merge into the new form. The GM has final say on whether the new form can wear or use a particular piece of equipment. Equipment that merges has no effect in that state.
