Dragon Form

Prerequisite: Half Dragon
You are blessed by either Bahamut or Tiamat, granting you a lesser Dragon form of your Draconic Ancestry's chosen dragon.

• Increase one of your Ability scores by 1, to a maximum of 20.
• When you use your action for your breath weapon instead of your bonus action, you may deal 1d6 additional damage, increase the DC by 1, and double it's range. 
• you can use your action to change into a medium sized form of your ancestral dragon. Your transformation lasts for 1 minute or until you end it as a bonus action. During this form you gain a flying speed of 30 ft, and you gain a bite attack as a unarmed strike which deals 1d10 piercing damage. If you already used your breath weapon, then at the start of your turn you may roll a d6, and regain your breath weapon on a 5 or 6 instead. In addition, once per turn you may deal bonus damage of your chosen damage type to a single target you've damaged, for an amount equal to your level. You may regain this form when you finish a long rest. During this transformation your equipment merges with you (You keep your AC, unless 13+ your Dexterity modifier is higher), including your weapons, but magical bonuses are transferred to your bite attack. In addition, for each minute that you haven't entered combat while in this form, you may extend it's duration by 1 minute, up to 10 minutes total. 

If you Ascend to Dragonhood then the third part of this feat is replaced by your new True Dragon form.
