Armor Class (AC) is one of the most essential mechanics in Dungeons & Dragons. It determines how difficult it is for an opponent to hit your character during combat. Having a high AC can be the difference between surviving a battle and succumbing to your enemy’s onslaught. In this article, we’ll cover the various ways to calculate your character’s Armor Class in D&D.
1. Base Armor Class
Your character’s base AC depends on the armor they are wearing. In most cases, the base AC is equal to 10 + the character’s Dexterity modifier. However, if your character is wearing armor or using a shield, their AC might be calculated differently. Here’s a quick rundown of how different armor types apply:
– No armor: 10 + Dexterity Modifier
– Light armor: Armor’s base AC + Dexterity Modifier
– Medium armor: Armor’s base AC + Dexterity Modifier (up to +2)
– Heavy armor: Armor’s base AC
For example, if your character is wearing medium armor with a base AC of 14 and has a Dexterity modifier of +3, their total AC would be 14 + 2 = 16.
2. Shield
If your character is using a shield, add an additional +2 to the base AC calculation above.
3. Class Features and Feats
Some classes have unique features that affect their Armor Class calculation. For instance:
– Monks: If not wearing armor or using a shield, can use 10 + Dexterity Modifier + Wisdom Modifier as their total AC.
– Barbarians: While not wearing armor or using a shield and raging, can use 10 + Dexterity Modifier + Constitution Modifier as their total AC.
Certain feats like “Defensive Duelist” grant an increase in AC under specific conditions. Take these into account when determining your total AC.
4. Spells and Magical Items
Various spells and magical items can temporarily or permanently alter a character’s Armor Class. Keep track of these bonuses as they change during play. Examples include the Mage Armor spell, which sets a character’s base AC to 13 + their Dexterity Modifier, or a Cloak of Protection, which provides a +1 bonus to their Armor Class.
5. Putting It All Together
To calculate your character’s total Armor Class, follow these steps:
a) Determine your character’s base AC based on their armor type or any class features.
b) Add any applicable modifiers from shields, feats, spells, or magical items.
c) Sum up all the above components to find the final Armor Class value.
Now you understand how to calculate your character’s Armor Class in D&D! Remember to keep track of any temporary or permanent changes that may affect your AC during gameplay. A high AC can significantly improve your character’s survivability in battle, so take advantage of opportunities to increase it whenever possible.
