This page details where to find the Jotun Blight in Vangrinn, Svatalfheim, part of the Dawn of Ragnarok DLC in AC Valhalla. There is only one Jotun Blight in the Vangrinn region.
Jotun Blight - North of Hodda Shelter
The Jotun Blight in Vangrinn is located in the swampy region north of the Hodda Shelter. As with other Jotun Blights, you’ll need to shoot the skull and then follow the trail to other skulls in the area. Once you’ve shot them all, the blight will disperse.
