How do you calculate a creature’s Armor Class (AC)?
Chapter 1 of the Player’s Handbook (p. 14) describes how to determine AC, yet AC calculations generate questions frequently. That fact isn’t too surprising, given the number of ways the game gives you to change your AC!
Here are some ways to calculate your base AC:
- Unarmored: 10 + your Dexterity modifier.
- Armored: Use the AC entry for the armor you’re wearing (see PH, 145). For example, in leather armor, you calculate your AC as 11 + your Dexterity modifier, and in chain mail, your AC is simply 16.
- Unarmored Defense (Barbarian): 10 + your Dexterity modifier + your Constitution modifier.
- Unarmored Defense (Monk): 10 + your Dexterity modifier + your Wisdom modifier.
- Draconic Resilience (Sorcerer): 13 + your Dexterity modifier.
- Natural Armor: 10 + your Dexterity modifier + your natural armor bonus. This is a calculation method typically used only by monsters and NPCs, although it is also relevant to a druid or another character who assumes a form that has natural armor.
Does Unarmored Defense work with a spell like mage armor?
Unarmored Defense doesn’t work with mage armor. You might be asking yourself, “Why don’t they work together? Mage armor specifies that it works on a creature who isn’t wearing armor.” It’s true that the target of mage armor must be unarmored, but mage armor gives you a new way to calculate your AC (13 + your Dexterity modifier) and is therefore incompatible with Unarmored Defense or any other feature that provides an AC calculation.
