Kall Fimbulbringer's Altar

The chamber of the eighth and last of the forsaken, deep under the northern ice. Offer three Malicious Blood at the bowl to wake him. The blood comes from Black Ice cores at Jotun Invasion sites, which appear in the five earlier biomes rather than up here, and the fight runs three phases for 47,000 health.

3 are placed per world. They go in the Deep North. Altitude above 80 m relative to sea level. Never closer than 1,024 m to another of its kind. Placed before ordinary locations, so it takes first pick of zones. Marked on the map once a player has been near it.

Summoning, the fight and the drops are on the Kall Fimbulbringer page.
