The missing companions of Sorrowful Jack Frost are located in the vicinity of the Huntsman Cabin within Volkodlak Tundra, but you will have to solve a small puzzle to locate them. Using Prime Ice Constructs, along with some Link Mechanisms near the cabin, you will be able to release the three Jack Frosts and reunite them once again. Here’s how to solve the puzzle and claim its rewards.
