Unarmored Defense Master

You’ve spent time accustomed to not wearing armor and it has made you better at it. You gain the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• While not wearing armor, your jump distance is doubled, and you use Dexterity score for calculating your jump distance rather than Strength if your Dexterity score is higher.
• While not wearing armor, your AC calculation is altered to the following = your AC while not wearing armor  - 2 + your proficiency bonus. To simplify, this results in a +1 bonus to your AC while not wearing armor at 5th level, and another +1 at 9th, 13th and 17th level. You must toggle this in character sheet, as DnDBeyond does not allow for specific programming like this.
  For an example, what this results in is that as a Monk is that your unarmored defense calculation is now 8 + your proficiency bonus + your Dexterity Modifer + your Wisdom modifier, rather than 10 + your Dexterity Modifier + your Wisdom modifier. For a different example, a Draconic Bloodline sorcerer’s Draconic Resilience feature AC calculation is now 11 + your proficiency bonus + your Dexterity modifier.
