Hardened Feathers

Your feathers and body toughened up to compensate with the inability to wear armor. You gain the following benefits:

• Increase your Strength, Constitution, or Charisma score by 1, to a maximum of 20.
• Your feathers harden. While you aren’t wearing armor, you can calculate your AC as 13 + your Dexterity modifier. You can use a shield and still gain this benefit.
• Your flight skills have allowed you to maneuver with ease in the air, granting you proficiency in acrobatics.
