Description: You can draw on the wisdom of the Dragon to prevent you from harm

Prerequisites: WIS 13

You may add your Wisdom modifier to your AC in place of your Dexterity modifier if your Wisdom modifier is higher. Your maximum bonus to AC is still limited by the Maximum Dexterity Modifier of whatever armor you wear. This bonus applies when you are flatfooted if your Wisdom modifier is higher than your attacker's.

If you have a class ability that already allows you to add your Wisdom modifier to your AC, this feat allows you to add your Wisdom modifier twice.
