How to reach it
- Complete Winding Tunnels and craft an Intricate Key.
- Find a Mörkhalla entrance in the Deep North and unlock it.
- Descend to the Malicious Ice and destroy it to trigger a Jotun Invasion.
What you get from it
- Memorial Coal from Krigen and Nornathread from Hexen.
- Armor moulds and a Vegvisir pointing toward the Aesir Passage.
- The trigger needed to earn Malicious Blood.
Tactics
- Bring the finished key, not its mould or cast.
- Save stamina before entering new rooms and control Hexen first.
- Carry portal materials and enough food for the invasion trip after the clear.
- Mark the Aesir Passage location when you use the Vegvisir.
Layout and three-run plan
Mörkhalla is a tall locked dungeon. Its entrance consumes one finished Intricate Key, so a mould or unprocessed cast cannot open it. Use the Grappling Hook where vertical access demands it, clear from the entrance downward, and expect Krigen and Hexen in compact rooms. Krigen can provide Memorial Coal; Hexen drop Nornathread.
Search for the Vegvisir that marks the Aesir Passage, along with armor moulds and other dungeon loot. At the bottom, destroy the Malicious Ice. That action triggers a Jotun Invasion somewhere on the world map, so check the map before traveling and bank the dungeon haul first.
You need three Malicious Blood for the Strange Bowl, while each invasion core yields one. Plan on three Mörkhalla entrances, three consumed keys, and three invasion clears. A portal outside each tower shortens recovery, but move valuable loot home before chasing an event marker that may be on another continent.
Frequently asked questions
How many Mörkhalla runs are needed?
Three. Each locked entrance consumes one finished key, and each completed invasion yields one of the three required Malicious Blood.
What should I find inside?
Look for the Aesir Passage Vegvisir, armor moulds, Memorial Coal, Nornathread, and the Malicious Ice at the bottom.
