Assassin's Creed Valhalla Update 1.1. 1, released on January 14 2021, added the timed challenges to the Ubisoft Connect platform. They reward you with five or ten Opal for completing them. The timed challenges are simple and easy to do as you play the game.
Thereof, can you buy opals in Valhalla?
Opal in Assassin's Creed Valhalla cannot be sold, nor can it be bought. Opal is a special type of currency, though you won't be able to spend it at a standard vendor.
Likewise, where do you get contracts in Valhalla? You unlock this quest after meeting the Thousand Eyes merchant in Ravensthorpe. The objective is simply, “Complete 10 contracts.” You can find contracts by speaking to various Thousand Eyes merchants throughout England.
Similarly, you may ask, why can't I pick up opals in Valhalla?
Opal is a scarce currency in AC Valhalla. There is a glitch that players are encountering wherein Opal from certain regions is missing such as Ledecestrescire and Grantebridgescire. There are opals missing from the map itself and in certain regions, the Opal isn't accessible.
Why is Reda in Valhalla?
Reda is believed to possess a 'Piece of Eden,' an Isu technology that grants her health and immunity from the passage of time. Reda is able to live a long life thanks to the powers of the Piece of Eden that also allows her to appear in both AC: Origins and Valhalla.
