Yuletide has come to Assassin's Creed Valhalla! All around the settlement of Ravensthorpe, your fellow vikings and revelers need your assistance to set up this most glorious celebration. And if you need our assistance in turn, we're more than happy to help.
Yuletide Quests - Cow Catcher Guide
To the western edge of your settlement is the cattle farm. Or, in my case, a tent that can be built into a cattle farm. To start this off, talk to Winfrith and you'll find out that Bertham, her son, let the cows for the feast escape. Undaunted, Eivor agrees to round up and kill the cows, and for good measure, she agrees to take Bertham with her.
Head on down to the docks and grab one of the small boats to row across to the opposite shore and you can then start catching cows! Three markers show up on the map, in roughly the same places as the picture above. You can either search on foot or use your raven to scout out where, exactly the cows are. Of course, once the cows realize they're being hunted you will then have to give chase, so make sure you're stocked up on arrows. One shot will take each of them down, no problem.
As you round up three of the four cows, Eivor talks to Bertham and finds out the whole story behind why he let the cows go and why he is unable to hunt for them himself. After you've gotten the third cow and finished all of the dialogue with Bertham, the marker for the fourth cow will appear on the map.
Head on over to the fourth cow and make sure Bertham is with you. What looks like a sitting duck, er, cow, at first is actually the only one you don't have to kill as Bertham takes care of it for you. Make sure to go and loot the body and then head back over to the Ravensthorpe settlement.
If you're going by map markers, this one glitches out and tries to direct you over to Sciropescire. Do NOT go there, just follow the marker for the settlement instead. You also don't have to take the boat back across, and in my case Bertham just decided to leap out of it halfway anyway.
Talk to Winfrith back at the Cattle Farm to wrap up the story and claim your rewards. You'll get 800 XP, 140 Yule Coins, and you have unlocked Bertham as an opponent in the Yule Brawl. Congratulations, you are now an official cow catcher.
