how to calculate ac dnd 5e

Of course, I'd be happy to help! In Dungeons and Dragons 5th Edition, Armor Class (AC) is a calculation of how hard it is to land a successful hit on a character or creature during combat. Your base AC is determined by the armor you wear.

Leather armor provides a base Armor Class of 11. But that's not all to consider. You can also add your Dexterity modifier to this base number if you're wearing light armor, which leather is.

You would simply add your Dexterity modifier to the base AC provided by your armor. For you, that would be 11 (leather armor) + 2 (Dexterity modifier), which gives you an AC of 13. This means an attacker would need to roll a 13 or higher on their attack roll to hit you successfully.
