@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?

@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
