Armor Class

Source: Player’s Handbook (2024) p. 361. Available in the SRD and the Free Rules (2024)

An Armor Class (AC) is the target number for an attack roll. AC represents how difficult it is to hit a target.

Your base AC calculation is 10 plus your Dexterity modifier. If a rule gives you another base AC calculation, you choose which calculation to use; you can’t use more than one.
