Boss	Kall Fimbulbringer

Entry	Malicious Blood

The Prison is where Kall Fimbulbringer, the final boss, spawns and fights you. It is an instanced area that you reach through the Aesir Passage, a giant gate in the Deep North.

Where to Find It

Each world gets up to three Aesir Passages. They can appear anywhere in the Deep North at an altitude of at least 80 metres, at least 1,024 metres apart, and they are among the points of interest that world generation places first. A Vegvisir found at Memorial Sites and in Mörkhalla reveals their location.

What's Inside

You need three Malicious Blood to open the passage. You offer the blood at a Strange Bowl, and all three are used up at once. If you offer fewer, the bowl shows how many are still missing. Kall Fimbulbringer appears 12 seconds after the offering.

When you enter, Kall Fimbulbringer is chained to two pillars in the centre of the arena, but he breaks free as you approach.

The arena has its own environment. It is always dark, and it counts as freezing and cold, like the weather outside.

Notes

Malicious Blood drops from the Malicious Ice at the centre of a Jotun Invasion, and destroying that ice ends the invasion. Destroying the Malicious Ice on the bottom floor of Mörkhalla starts a Jotun Invasion.
