Understanding how to calculate Armor Class (AC) in Dungeons & Dragons 5th Edition (5e) is crucial for any player looking to keep their character alive during combat. AC represents how difficult you are to hit in combat, and it can greatly influence the outcome of a battle. Below, we’ll explore five different methods to calculate your AC, as well as helpful tips, common mistakes, and troubleshooting advice.
Method 1: Basic AC Calculation
The most straightforward method of calculating your Armor Class is by using your Dexterity modifier and your base AC. Most characters start with a base AC of 10, and if you are wearing light or no armor, you add your Dexterity modifier to this base value.
Calculation Steps:
- Base AC: Start with 10.
- Add Dexterity Modifier: For every point of Dexterity above 10, you gain a +1 bonus.
Example: If your Dexterity score is 16, your modifier is +3. So, your AC would be 10 + 3 = 13.
| Dexterity Score | Dexterity Modifier | Calculated AC |
|---|---|---|
| 10 | +0 | 10 |
| 12 | +1 | 11 |
| 14 | +2 | 12 |
| 16 | +3 | 13 |
| 18 | +4 | 14 |
⚔️ Pro Tip: Always check if your character has proficiency with light armor, as this can further increase your AC!
Method 2: Medium and Heavy Armor
Different types of armor provide different base ACs. The key is to understand the armor’s description in the Player’s Handbook.
- Medium Armor: Base AC of 12 + Dexterity modifier (max +2).
- Heavy Armor: Base AC typically ranges from 14 to 20, depending on the armor type, but it does not allow you to add your Dexterity modifier.
Calculation Steps for Medium and Heavy Armor:
- Determine the Armor Type: Choose from medium or heavy armor options.
- Add Modifiers: For medium armor, add only up to +2 from Dexterity. For heavy armor, use the base AC provided by the armor.
Example for Medium Armor: If you are wearing studded leather armor (base AC 12) with a Dexterity score of 14 (modifier +2), your AC would be 12 + 2 = 14.
Example for Heavy Armor: If you wear plate armor (base AC 18), your AC remains 18 regardless of your Dexterity modifier.
🛡️ Pro Tip: Be aware of the penalties for wearing heavier armor, especially if you are a spellcaster!
Method 3: Unarmored Defense
Some classes, such as Monks and Barbarians, have an ability called Unarmored Defense. This allows them to calculate AC differently, relying on their Dexterity and either Wisdom (for Monks) or Constitution (for Barbarians).
Calculation Steps:
- Monk AC: 10 + Dexterity modifier + Wisdom modifier.
- Barbarian AC: 10 + Dexterity modifier + Constitution modifier.
Example for a Monk: If your Monk has a Dexterity score of 16 (modifier +3) and Wisdom score of 14 (modifier +2), your AC would be 10 + 3 + 2 = 15.
Example for a Barbarian: If your Barbarian has a Dexterity score of 14 (modifier +2) and Constitution score of 16 (modifier +3), your AC would be 10 + 2 + 3 = 15.
🌟 Pro Tip: Utilize Unarmored Defense to maintain higher mobility and avoid the disadvantages of armor!
Method 4: Shield Bonus
Using a shield can provide a significant boost to your Armor Class. When wielding a shield, you gain a +2 bonus to your AC.
Calculation Steps:
- Base AC: Start with your calculated base AC.
- Add Shield Bonus: Simply add +2 to your AC while using a shield.
Example: If your base AC (without armor) is 13 and you are using a shield, your new AC would be 13 + 2 = 15.
⚡ Pro Tip: Combining a shield with other forms of protection, like spells or abilities, can create a formidable defense!
Method 5: Magical Effects and Items
Certain spells, items, or class features can grant temporary or permanent modifications to your Armor Class. These can include spells like Mage Armor or Shield, which can significantly increase AC.
Calculation Steps:
- Cast the Spell or Use the Item: Ensure the effect is active.
- Apply the Bonuses: Follow the spell or item description to determine how much it adds to your base AC.
Example: If you are a wizard who has cast Mage Armor, your AC becomes 13 + Dexterity modifier. So, if your Dexterity score is 14, your new AC would be 13 + 2 = 15.
🌈 Pro Tip: Always consider the context of the battle. Sometimes it’s better to use a spell that can protect multiple allies!
