Unarmored Defense

Prerequisite: Dexterity 13 or higher, 13 or higher in Constitution, Intelligence, Wisdom, or Charisma

You've spent time learning to augment your defensive technique with more than just agility. You gain the following benefits:

• While you are wearing no armor and not wearing a shield, your AC equals 10 + your Dexterity modifier + the modifier of the ability score you increased with this feat (maximum 3).

The AC increase doesn't stack with features such as Bladesong, which adds your Intelligene modifier to your AC. You must choose between this, or your Bladesong feature
