How to Calculate AC 5e?

Calculating Armor Class (AC) in Dungeons & Dragons 5th Edition (5e) is a crucial aspect of the game, as it determines the likelihood of a character’s success in combat. In this article, we will provide a comprehensive guide on how to calculate AC 5e, including the formula, armor types, and additional factors that affect the calculation.

The Basic Formula

The basic formula for calculating AC 5e is:

AC = 10 + Dexterity modifier

What is Dexterity Modifier?

The Dexterity modifier is a numerical value that represents a character’s agility and reflexes. It is calculated by subtracting the character’s Dexterity score from 10. For example, if a character has a Dexterity score of 16, their Dexterity modifier would be +3 (16 – 10 = 3).

Adding Armor and Shield

When a character wears armor or uses a shield, they can add the armor’s AC bonus to their base AC. The AC bonus for different types of armor is listed below:

For example, if a character wears leather armor, their AC would be:

AC = 10 + Dexterity modifier + 2 (leather armor) = 12 + Dexterity modifier

Additional Factors

There are several additional factors that can affect a character’s AC 5e:

• Constitution modifier: If a character is a Barbarian, they can add their Constitution modifier to their AC.
• Wisdom modifier: If a character is a Monk, they can add their Wisdom modifier to their AC.
• Magic items: Certain magic items, such as a Ring of Protection, can grant a bonus to a character’s AC.
• Spell effects: Certain spells, such as Shield, can grant a temporary bonus to a character’s AC.

Example Calculations

Let’s calculate the AC for a few different scenarios:

• Fighter in leather armor: Dexterity modifier = +3, AC = 10 + 3 + 2 (leather armor) = 15
• Barbarian in plate armor: Dexterity modifier = +2, Constitution modifier = +1, AC = 10 + 2 + 6 (plate armor) + 1 (Constitution modifier) = 19
• Monk in chainmail: Dexterity modifier = +4, Wisdom modifier = +2, AC = 10 + 4 + 4 (chainmail) + 2 (Wisdom modifier) = 20

Conclusion

Calculating AC 5e is a straightforward process that requires considering a character’s Dexterity modifier, armor type, and any additional factors that may affect their AC. By following the formula and considering these factors, players can ensure that their characters are properly protected in combat.
