Hello there,
I have recently purchased Dawn of Ragnarok and I have started it during the main campaign, my progress was right at the Settling Dawn quest early in the game, after that I could start Dawn of Ragnarok. My power level is 25 and I have seen no pop-up regarding the boost (you should get it if you are blow 310, https://www.ubisoft.com/en-gb/help/assassins-creed-valhalla/gameplay/article/boosting-eivors-power-level-to-play-assassins-creed-valhalla-dawn-of-ragnarok/000101177).
I could beat the lava dudes pretty easily, but I got stomped by Surtr (at first I though you were supposed to die because of how overpowered he is, well apparently not). How do I receive the boost? Do I get it sometime after beating Surtr? I know that I can try to start a New Game and choose the Dawn of Ragnarok adventure and maybe receive the boost that way, but after checking the info from here: https://www.ubisoft.com/en-us/help/assassins-creed-valhalla/gameplay/article/starting-assassins-creed-valhalla-dawn-of-ragnarok/000101176, "To have a saved game that will allow you to play Assassin's Creed Valhalla and Dawn of Ragnarök interchangeably, please progress through the main campaign and start Dawn of Ragnarök in-game", which is what I wanted and what I did. I need some help here, please. Thank you in advance.
Wishing you all best!
