Obtained from1 per Jotun Invasion core destroyed
Used for3 offered at the Strange Bowl in Aesir Passage

How to obtain

  1. Unlock Mörkhalla with an Intricate Key.
  2. Destroy the Malicious Ice at the dungeon bottom to start a Jotun Invasion.
  3. Travel to the invasion and destroy its ice core to obtain one Malicious Blood.
  4. Repeat until you have three, then offer them at the Aesir Passage.

What it's used for

  • Offer three in the Strange Bowl to enter Kall's Prison.
  • Use it only for the Kall Fimbulbringer summon chain.
  • Plan for repeated dungeon and event runs rather than a single clear.

Common mistakes

  • Confusing it with Sacrificial Blood, which drops after the boss.
  • Leaving Mörkhalla without noting where the triggered invasion appeared.

Three invasions, three blood

One Mörkhalla run produces one opportunity for Malicious Blood. At the bottom of the dungeon, destroy the Malicious Ice to trigger a Jotun Invasion. The event can appear anywhere on the world map, rather than beside the dungeon or only in the Deep North. Open the map as soon as the trigger fires, find the new event marker, and plan the trip before leaving your portal network.

At the invasion, fight through Krigen and Hexen while working toward the central Malicious Ice core. Destroying that core ends the event and gives one Malicious Blood. The invasion has no short raid timer that completes the objective for you, so arrive with repair condition, food, healing meads, and portal materials. Repeat the key, dungeon, and invasion sequence three times.

Carry all three Malicious Blood to the Strange Bowl in the Aesir Passage. The offering opens the route to Kall's Prison and begins the final boss encounter. Malicious Blood is the pre-fight offering; Sacrificial Blood is a different item dropped by Kall and used at the Sacrificial Stones after the fight.

Frequently asked questions

How many Malicious Blood are required?

Three are offered at the Strange Bowl in the Aesir Passage.

Where does the invasion appear?

It can spawn anywhere on the world map. Check the event marker immediately after breaking Malicious Ice.

Invasion pitfalls and safe storage

  • Searching only around Mörkhalla for the invasion instead of checking the full world map.
  • Waiting for a raid timer to expire; the Malicious Ice core must be destroyed.
  • Taking one blood to the Strange Bowl before completing the other two loops.

Safe storage plan

Portal each blood home after its invasion and place all three in one labeled chest. The reward is light, but carrying it into the next locked dungeon adds needless recovery risk. Keep Memorial Coal and Nornathread in separate storage because neither substitutes for the offering.

After the third event, bring the complete stack to a recovery portal outside the Aesir Passage. The bowl consumes the pre-fight offering and opens the Prison route, so finish repairs, food selection, and spare-gear placement before interacting.

If the event marker is distant, treat travel as a separate expedition. Leave Mörkhalla materials at base, pack only the combat and portal supplies needed for the invasion, and repair again before the return trip. The blood reward can portal home once the core is destroyed.
