Deep North tierMisc
Malicious Blood
There's something unsettling about this clotted, frozen mass.
Malicious Blood is a material broken out of Malicious Ice, the black cores that form in the Deep North. It weighs 1, stacks to 50 and can be carried through a portal. Three are needed to summon 
Kall Fimbulbringer, and the cores only appear during a live Jotun invasion, which is the real gate on the endgame.
