Expected behavior: Mage armor + shield + dex modifer of +3 = 18 AC.

Current behavior: Flat 16 AC regardless of shield equipped/unequipped.

Mage armor should stack with equipped shield.

@mikemearls @JeremyECrawford Does a mundane shield count as armor with respect to the Mage Armor spell?


@KeatonStamps @JeremyECrawford no - the rules categorize shields and armor as two separate things
