Thickskull is a Norse Man and an Assassin’s Creed Valhalla NPC you can find in Eurviscire arguing with the Loki Rabbit. Talking to Thickskull triggers the Dellingr Rabbit World Event, which is very short. Your objective is to defeat Thickskull in a fistfight; however, there is one hidden reward you can miss while playing this quest.
AC Valhalla Dellingr Rabbit World Event Location
Look for the world event north of Picheringa in Eurviscire. Here, you’ll find a Norse Man (Thickskull) asking a rabbit to send him a champion to prove his might.
How To Find Loki’s Rabbit Secret Treasure
To complete the Assassin’s Creed Valhalla Dellingr Rabbit World Event, talk to Thickskull. There is no dialogue here, so get ready to fight him.
Thickskull is a very accessible opponent, and depending on your level, you can deal with him pretty fast. If you can’t, consider leveling up. Once you defeat Thickskull, talk to him, and the event will end; however, you should not leave the area.
Instead, focus on the rabbit nearby. When you get close, the rabbit runs away. Follow the Loki Rabbit, which will take you to a hidden chest (pictured below). Inside, you’ll find 10 Silver and the Andvaranaut Ring, which is quite expensive.
