Do You Subtract Dex from AC in 5E?
In Dungeons & Dragons 5th Edition, determining Armor Class (AC) can be a complex task, especially when it comes to character builds and gear choices. One common question that players and DMs alike have is whether the Dexterity (Dex) score is subtracted from AC. In this article, we’ll explore the rules and provide answers to help you navigate the world of 5E.
The Basics
Before we dive into the specifics, let’s take a look at the armor class calculation formula:
- Base Armor Class (BAC) + Dexterity Modifier + Armor Bonus (if applicable) = Armor Class
The Dexterity score is added to the Base Armor Class, as it represents the character’s agility and ability to dodge attacks.
Heavy Armor and No Dexterity Modification
Heavy armor, however, changes the equation. According to the Player’s Handbook (PHB), "Heavy armor doesn’t add your Dexterity modifier to your Armor Class." This means that if your character wears heavy armor, their Dexterity score has no effect on their Armor Class.
Here’s a summary of the table:
| Armor Type | Dexterity Modifier Effect |
|---|---|
| Light Armor | Adds to Armor Class |
| Medium Armor | Adds to Armor Class |
| Heavy Armor | Does not add to Armor Class |
But What About a Negative Dexterity Modifier?
Another common question is what happens when a character has a negative Dexterity modifier, such as a score of 8. In this case, the Dexterity modifier is subtracted from the Base Armor Class, reducing the character’s overall AC.
Example: Character with Dexterity 8
Let’s say we have a character with a Dexterity score of 8. Their Base Armor Class is 11. With the Dexterity modifier of -1, we subtract the modifier from the Base Armor Class:
11 (Base Armor Class) – 1 (Dexterity modifier) = 10
In this example, the character’s total Armor Class would be 10.
Conclusion
In conclusion, the answer to the question "Do you subtract Dex from AC in 5E?" is: it depends on the armor type. When wearing light or medium armor, Dexterity modifiers are added to the Base Armor Class, while heavy armor does not modify the character’s Armor Class. However, when a character has a negative Dexterity modifier, it is subtracted from the Base Armor Class, affecting their overall AC.
Remember to always check the rules and consult the Player’s Handbook for the most up-to-date and accurate information. Happy gaming!
