Age of Empires 4 Complete Masteries & Rewards Guide

Age of Empires 4 Masteries are essentially in-game achievements for completing certain challenges for each of the eight civilizations. The rewards you receive for completing Masteries include 1,000 XP, portraits, sigils, monuments, other profile cosmetics, and short historical facts. There are no new units, civilizations, or extra campaigns to unlock.

You can see all of the Masteries in Age of Empires 4 by clicking the crown and laurel icon to the right of the notifications icon at the bottom of the main screen. It’s to the right of the chat message box. When the Masteries menu appears, you’ll see tabs for each civilization and AoE 4‘s training modules. I’ve completely updated this guide to include those from The Sultans Ascend DLC.

Age of Empires 4 Complete Masteries & Rewards Guide

Each nation has 15 Masteries each, and there are five separate ones for completing Art of War challenges or Norman campaign missions. When you click on a tab, you’ll see all of the challenges related to it, including the requirements and rewards for each challenge when you click on them.

It’s important to note that you can only complete challenges in the order they are presented. For example, you can only complete the Assize of Arms challenge for the English after you have finished the Nice Try, Spy challenge.

Further, you can only complete one challenge per match. I’ve confirmed through play, however, that you can complete these in multiplayer or Skirmish mode. And for some challenges, it doesn’t matter if you play against any opponent. You can play a custom Skirmish match alone if you prefer. You’ll see the Masteries you’ve completed at the end of each match.

Below is a list of all Masteries for every civilization and the training/campaign tab, as well as the rewards you’ll receive for completing them, as laid out by Age of Empires 4. Click the links below to jump to each civilization.
