To get the "All Roads Lead to Dublin Trophy" in the Wrath of the Druids expansion on Assassin's Creed Valhalla you'll need to complete a quest requiring you to increase Dublin's Renown to 5. Here's our guide on how to do that.
How to improve Dublin's Renown
By speaking with Azar, you will be able to trade with different kingdoms. For the exchange to take place, you are going to need resources such as Luxuries, Texts, Clothing or Delicacies.
Each exchange brings a different number of experience points, based on whether it's marked gray, bronze or gold. Gold is the best bet for levelling up quickly, but naturally requires a lot more goods. It will take time and some effort to gather resources.
Note: Each level you increase will grant you new contracts with new lands, which will give you more goods to sell.
Conquer Trade Posts
Trade Posts are the best way to sustainably get the resources to trade with other kingdoms. Each Trade Post will produce its own merchandise, such as Clothing or Texts, so it will be necessary to conquer all the Trade Posts.
Complete Royal Demands
As your adventure progresses, you will have to fulfill Royal Demands. Don't limit yourself to doing only those requested by the main quest -- do them sustainably. They are often stealth missions.
Loot your opponents
Chests are scattered all over Assassin's Creed Valhalla, and some will grant you goods to sell.
Why do you need to increase Dublin's Renown?
Improving Dublin's Renown will grant you additional skill points, and allow you to collect Trade Posts. Also, when you do trade with foreign countries, you will be able to receive pieces of equipment. Additionally, Azar will give you a coin from the Dublin Set each time you level up the region's influence.
The story of this expansion revolves around the influence of Bárid in Ireland, and although the strength of the army is important, remember that the main goal is to increase the commercial influence of the region.
