The Enraged Jack Frost is a snowman in Snezhnaya who is furious that his pair of Ice Cubes do not match the frame sitting opposite them. You calm him down by reshaping those cubes so both sides line up, which spawns an Exquisite chest and turns him into a happy, jumping No-Longer-Enraged Jack Frost.
Quick answer: Melt the far cube with a Basic Heat Source until it matches the opposite frame, dismantle the heat source, melt the second cube down to a smaller size, then build a Cube-form Prime Ice Construct next to the smaller cube so both structures mirror the ones across from them.
What you need before starting
This puzzle runs entirely on Prime Ice Constructs. You gain access to them through the Eye of Graeae, which you receive when you first arrive at Snezhnaya. With that unlocked, you can open the Prime Ice Construct menu and build, shape, and resize Ice Cubes freely, along with a Basic Heat Source to melt them.
If you have already finished the Yarina Prime Ice Construct quest, the matching concept here will feel familiar. Both Yarina and the snowman dislike unsymmetrical structures. The difference is the payout. Yarina’s quest hands over two Exquisite chests, while the Enraged Jack Frost only gives one.
Enraged Jack Frost location
The Enraged Jack Frost stands northwest of the Inverted Glaciers Domain. The fastest route is to teleport to the waypoint west of the Relics of the Fallen Grace Domain, then travel northeast until the angry snowman comes into view beside his mismatched Ice Cubes.
How to solve the matching Ice Cube puzzle
The goal is to make the two cubes on the snowman’s side match the two structures directly across from them. One cube needs to melt down to a matching shape, the other needs to shrink smaller, and the final piece needs a fresh Cube built to complete the set.
How to confirm it worked and the reward
When all structures on the snowman’s side match the ones opposite them, the puzzle resolves on its own. The Enraged Jack Frost transforms into a No-Longer-Enraged Jack Frost, jumping around excitedly, and a single Exquisite chest appears for you to open.
If the chest does not spawn, the cubes are not fully matched yet. Compare each cube against the frame directly across from it, since one needs to end larger, one needs to end smaller, and the last slot must be filled with a freshly built Cube. Reshape whichever piece is still off and the snowman will settle.
