At 3rd level, you learn to hide your draconic form under a humanoid form, and back again, as an action. This is a transmutation effect, similar to the alter self spell, except it has no duration and does not require concentration. When you first transmute to your alternate form, choose a humanoid race (most commonly dwarf, elf, halfling, or human). Once this choice has been made, it
cannot be changed.
When you take on your alternate form, you always transform into the form of the same individual, and can be recognized as such by those familiar with your alternate form. While not recognizable as a dragon, your alternate form has a telltale sign hinting at your draconic nature, such as eyes or hair matching your dragon color.
The form matches your sex, and its size is determined by its race, but it’s age and other features are determined by you when you first take on the form. As you age and grow, you can choose to have your alternate form age relatively with you, or you can choose to leave it ageless.
When you adopt your alternate form, your statistics remain the same, except you do not have access to your draconic armaments (except your armor class), breath weapon, or dragon wings, your size is that of the race you chose, and your speed is 30 ft. When you adopt your alternate form, equipment that you are wearing changes size to accommodate your humanoid size and shape, except for mundane barding. When you transform back into your draconic form, weapons carried and armor and clothing worn by your humanoid form merge with you and becomes nonfunctional, except you do still retain access to their magical bonuses and features; an armor’s magical AC bonus is added to yours, and a weapon’s features are added to your draconic armament attacks.
You also gain proficiency in simple weapons. Your natural form’s claws lack the ability to wield weapons, but your alternate form doesn’t have this shortcoming.
