Draconic Shapeshifting

You gain the ability to turn into an adult chromatic dragon of your choice as an action. Your size, speed (including gaining the dragon's flying speed) and natural armor class changes to match the dragon you transformed into. Furthermore, you can use the dragon's breath weapon and natural weapon attacks instead of your own. If you take the attack action using the dragon's weapons, you can make two claw attacks and one bite attack instead of your regular two attacks. You retain any benefits you get from class features (such as rage) or your demigod powers (such as bonus to natural weapon attacks) for these attacks. Unless that description says otherwise, any ongoing effects on you—conditions, spells, curses, and the like—carry over from one form to the other. You revert to your true form if you die. You also gain the dragon's damage immunity (and condition immunities), senses and any special abilities it may have (such as Ice Walk). Finally, you gain a bonus to one of your stats determined by the dragon, as shown below:

Black: +3 to Charisma,
Blue: +3 to Wisdom,
Green: +3 to Intelligence,
Red: +3 to Strength,
White: +3 to Constitution,
Yellow: +3 to Dexterity
