@BrailSays "Natural Armor, considered 'Unarmored' or 'Light Armor' ?" Neither. Natural armor is its own thing. — Jeremy Crawford (@JeremyECrawford) January 21, 2015

@BrailSaysDruid/Monk,unarmored defense usable in shapeshift forms? The druid/monk could use Unarmored Defense or the beast's AC calculation. @mikemearls — Jeremy Crawford (@JeremyECrawford) January 7, 2015

@wax_eagleIs there a reason why the wording is inconsistent between Mage Armor and Unarmored Defenses? Mage Armor uses “Base AC” The difference isn't intentional. — Jeremy Crawford (@JeremyECrawford) August 26, 2014

@JeremyECrawford Monk's Unarmored Move, does it increase Aaarakocra's fly speed? Speed seems to be walking speed, it's a bit confusing. — JohnnyD (@JohnnyD1722) July 1, 2015 Unarmored Movement is intended to increase a monk's innate speed, including an aarakocra monk's flying speed. https://t.co/m9RjAp68GK — Jeremy Crawford (@JeremyECrawford) July 7, 2015

@Hard_ViceWill Mage Armor work with Unarmored Defense? I’m guessing since each specifies an AC formula, MA would replace UD. "Will Mage Armor work with Unarmored Defense? I’m guessing since each specifies an AC formula, MA would replace UD." Correct. — Jeremy Crawford (@JeremyECrawford) January 21, 2015

@BrailSays "RAW,would a monk/druid retain Unarmored Movement while shifted?" Yes. — Jeremy Crawford (@JeremyECrawford) January 21, 2015

@ironwizard13Has there been an official answer to if Unarmored Defense and Draconic Resilience work together? Again TY for you time. Different AC calculations don't stack. — Jeremy Crawford (@JeremyECrawford) January 7, 2015

@JeremyECrawford just to be clear, something like mage armor wouldn't stack with a monk's unarmored defense, would it? — AudibleShrug (@AudibleShrug) December 19, 2017 If the game gives you different ways to set your AC, you choose which one to use. Bonuses and penalties are then applied to that AC. #DnD https://t.co/Qbf0rYvKbo — Jeremy Crawford […]
