Spiritual Defense is an event quest under the new Ostara Event in Assassin’s Creed Valhalla.
Your task is to perform a ritual and then eliminate some of the spirits.
Here’s a walkthrough of Spiritual Defense in AC Valhalla.
To begin the quest, talk to Alvis in Ravensthorpe. His exact location is shown in the map, marked by the quest symbol.
Talk to Alvis
You will need to wait to nightfall to speak to Alvis at the location. To fast forward time, you can just meditate.
You will meet Ake instead of Alvis.
Find and light the firepits
You will be asked to light eight firepits. The first one is near you.
For the next seven firepits, the locations are all marked on the map as shown below.
Once you’re done with the firepits, talk to Ake again. Then, follow him to the ritual area.
Activate the Foul Totem at the top of the hill. This can only be done at nightfall.
Kill the spirits
Three animal spirits will then spawn. You just need to defeat them all.
The quest ends after they’re dead. You should get 140 festival tokens.
