I dropped into a frozen grotto and the Eye of Graeae started humming under my palm. A block of Prime Ice rose where I needed a stepping stone, and suddenly a locked chest wasn’t locked anymore. You can hear the map rearrange itself when you place the right piece.
I’ve been testing Snezhnaya’s new toolkit across quests, puzzles, and livestreams; I’ll tell you what matters, what to avoid, and how to make a single Prime Ice decision turn a frustrating detour into a straight line. You’ll get my hands-on tips, plus a few ways the community (Reddit, YouTube creators, and Twitch streamers) are already bending these mechanics to their will.
I spilled coffee while reading the 7.0 notes—then I had to try the Eye of Graeae immediately.
What Prime Ice actually is: Prime Ice is an exploration resource tied to the Eye of Graeae you receive when arriving in Snezhnaya. It lets you fabricate temporary devices—platforms, ziplines, heaters, signs—using Prime Ice materials and Eye of Graeae energy. These are not cosmetics: they change geometry, open hidden routes, and can break or remove world objects when used correctly.
The feature blends construction and deconstruction. You’ll build a cube to prop a door, then place a heat source to melt sealed ice, and sometimes dismantle a crystalline shell to reveal a chest or a shortcut. Treat Prime Ice as both a tool and a key: it solves movement puzzles and reveals rewards.
How do I use Prime Ice Constructs?
Quick, practical steps you can follow right now:
- Carry Prime Ice in your inventory and watch the Eye of Graeae energy bar—both are required to place constructs.
- Open the Prime Ice radial and pick a construct. Placement is contextual: some surfaces refuse anchors, some do not.
- Each construct has a hard limit in the area. You cannot spam Link Mechanisms to build a highway across Snezhnaya.
- Dismantle interactables with the construct tool when the prompt appears—this is how you reveal secret passages and chests.
For visual guides, search creators on YouTube and attempts posted to Reddit and Discord; streams on Twitch often show creative uses—especially for Link Mechanisms and Launching Platforms. Hoyoverse’s patch notes and Moyens I/O-style guides are good for updates and patch-specific changes.
At my desk I sketched a flowchart of every construct while my cat demanded attention.
The short list: there are nine primary Prime Ice constructs you will use repeatedly. Some story sections add temporary variants, but the core pieces are what you’ll learn to depend on.
| Prime Construct | What it Does |
|---|---|
| Cube | The most basic construct, which is used to obstruct things or to act as a foothold. Many puzzles use it for keeping doors open or to stop something. |
| Basic Heat Source | This is a heat source that helps you melt certain ice. Doing so can often reveal hidden treasure or secret passages. |
| Link Mechanism | The new zipline technology that you can you setup yourself. Similar to Arknights Endfield, but with a limit. |
| Grappling Gun | Used to pull open latches, or to pull or anchor a platform. |
| Launching Platform | Throws the player up in the air, allowing them to gain good height without much cost. |
| Storage Device | Allows players to store materials or items from their inventory. |
| Ambient Bollard | Gives various buffs for the surrounding area, like elemental energy regeneration, stamina regeneration, and more. |
| Sign: Icon | Can place a sign on the ground. |
| Sign: text | Can place a text message on the ground. |
What are the Prime Ice Construct types?
Memorize the nine—and remember how they interact. For example, a Cube plus a Grappling Gun can anchor a swinging platform; a Basic Heat Source will melt sealed ice faster when placed near concentrated frost nodes. Link Mechanisms are the mobility tool you’ll reuse most often, but they are capped per area.
Can I place constructs outside Snezhnaya?
No. Prime Ice placement only functions inside Snezhnaya. When you step out of the Cryo region the Eye of Graeae’s construction tools go dormant. Treat Snezhnaya as a workshop where each area hands you a set number of pieces—if you waste them, you may miss chests or secret paths.
Quick strategy notes I use on stream:
- Save at least one Cube for emergency doorstep puzzles; many doors need weight to remain open.
- Use Launching Platforms for vertical scouting instead of climbing; it saves stamina and can reveal ledges quickly.
- Ambient Bollards are small ROI but stack well near farming nodes and world bosses when you need short-term buffs.
- If you see crystalline seals, think dismantle—a Basic Heat Source or targeted construct often breaks them and drops loot.
Players in community hubs—Reddit threads, dedicated Discord servers, and YouTube channels—are already sharing puzzle layouts and optimal placements; if you want quick visual walkthroughs, those creators usually show the placement sequence step-by-step.
The Prime Ice Construct changes how Snezhnaya feels: it gives you permission to rewire the environment and punishments for careless placement. Think of the kit as a Swiss Army knife for explorers, and its presence a lighthouse in a blizzard for puzzle hunters.
So—what risky, creative Prime Ice trick will you try first?
