What is ac calculator dnd?

The ac calculator dnd is a specialized utility used by players and Dungeon Masters to determine how difficult it is for an enemy to land a physical blow on a character. In Dungeons & Dragons 5th Edition, Armor Class (AC) represents a combination of physical protection, magical defenses, and the ability to dodge.

Accurately calculating your AC is vital for combat balance. High AC characters (Tanks) like Paladins might reach values over 20, while squishy spellcasters might rely on spells like Mage Armor or high Dexterity to avoid being hit.

How to Calculate ac calculator dnd (Example)

1. Identify Armor Type: Let’s say you wear Scale Mail (Base 14).
2. Calculate Modifiers: Your Dex is 16 (+3 modifier). Since Scale Mail is Medium, Dex is capped at +2.
3. Add Equipment: You use a Shield (+2).
4. Final Calculation: 14 (Base) + 2 (Max Dex) + 2 (Shield) = 18 AC.
