It looks like you’ve finally met Reda and discovered the delicacies that the Opal can offer in AC Valhalla. As Eivor, there’s undoubtedly a lot to discover in Ubisoft’s expansive, brilliant game, and the Opal element plays a major role in terms of both exploration and in-game currency.

From Opal's function to the best ways to obtain it, here's a detailed guide on everything you need to know about Opal in AC Valhalla.

Opal is one of the currencies that can be used to purchase exotic goods in Assassin’s Creed Valhalla. Of all the resources available in the game, Opal is considered the most valuable as it allows you to trade with Reda, an important NPC in the game. This currency cannot be bought or sold and there are only a few ways available in the game to obtain it.

Once you reach rank 3, the Thousand Eyes shop, led by Reda, will appear in your character’s settlement. Reda is a young boy who is a very important member of the Thousand Eyes network, members of which you will come into contact with at various locations throughout the game. Thousand Eyes shops are scattered throughout the AC Valhalla world, allowing you to spend your opals. Members of the network can be identified by a woven cross badge that adorns the shelves of their shops.
