What is AC in D&D?

In Dungeons and Dragons (D&D), Armor Class (AC) represents a character’s defense against attacks from monsters, and it is calculated based on the character’s Dexterity modifier, the type of armor they are wearing, and other factors that can increase or decrease their AC. The AC is a crucial defensive element in the game, as it determines how difficult it is for enemies to hit a character, making it an essential aspect of character building and combat strategy.
