[QUOTE="Charlaquin, post: 7509550, member: 6779196"] Yes, that is correct. Mage Armor stacks with the shield spell, the same way that shields stack with armor. There are three ways of modifying your AC, (although one of them only occurs in one specific spell.) 1. An item, ability, or spell gives you a way to calculate your AC.

So, for example, a character wearing chain mail calculates their AC as 16, and a shield adds +2, for a total of 18.

You calculate your AC as normal, and if the result is less than 16, the spell sets it to 16. So, a character with 14 Dex wearing hide armor calculates their AC as 12+Dex (up to +2)=14.
