Chest Armor Recipe (Týr’s Lost Unity Cuirass)
Head to the new beach that you can dock in the Forgotten Caverns. Approach the corpse near the tunnel for the spirit to appear. Talk to the spirit to receive this favor. In this side mission, you have to find and defeat three hel-walker crews. Their locations will be conveniently marked in the map. The hel-walkers are resistant to the Leviathan Axe’s ice damage and they can be easily dealt with the Blades of Chaos once you have it but it’s still manageable in case you face them as early as you can. You can find and destroy the crews in any order you want.
Iron Cove
Dock at the beach southeast of Iron Cove to find this hel-walker crew. This could be a dangerous encounter because there are high-level wulvers among them. However, if you focus on the hel-walkers and defeat them first, the objective will still be updated and counted even if you die.
Isle of Death
This island is located the towers of Niflheim and Asgard. Dock at the northern beach then pass through the narrow corridor to reach a clearing where another hel-walker crew is located. This group has a hel-viken and three hel-shadows.
Niflheim Tower
Dock at the base of the tower and use the lift to reach the top. A hel-reaver guard and two hel-reavers will be waiting at the top.
After defeating all three crews, report back to the spirit to complete the favor and receive your rewards. Bring the armor recipe to any of the dwarven brothers to register it to their shop and allow you to craft it once you have the necessary materials.
