What this page is about
This guide is for Leyak pressure and X-Ray response. It is not a Nocturnal Anomaly capture route and it is not a general Night Realm farming page. If you need Test Tubes, Anomaly material, or plant-food crafting, use the Anomaly capture guide.
The Leyak problem is different: it interrupts travel and base work until the player has a dependable X-Ray answer. A good route solves three questions before the encounter happens:
- Where is the X-Ray Lamp in your inventory?
- Which base area has X-Ray Tower coverage?
- Are you farming Leyak Essence, escaping pressure, or setting up containment?
Confirmed response tools
| Tool | Confirmed use | Best practical role |
|---|---|---|
| X-Ray Lamp | Stops the Leyak and can produce Leyak Essence | Portable response during exploration |
| X-Ray Tower | Fixed X-Ray coverage for Leyak pressure near the tower | Base or staging-room protection |
| Leyak Essence | Drops from successful X-Ray handling of the Leyak | Resource pickup after the threat is controlled |
| Containment Unit: 91 | Can contain the Leyak when the Leyak is drawn near and hit with the correct X-Ray response | Planned long-term control |
Do not treat the X-Ray Lamp like a normal weapon. Its job is not damage routing or enemy clearing. Its job is to stop the Leyak encounter cleanly enough that you can either continue the route, collect essence, or reset safely.
Field response workflow
Use this sequence any time Leyak pressure is active away from base:
- Put the X-Ray Lamp on a consistent hotbar slot before leaving.
- Keep one clear retreat line instead of running deeper into unknown rooms.
- When the Leyak appears, stop sprinting blindly and face the threat.
- Use the X-Ray Lamp long enough to force the response.
- Confirm the area is safe before checking for Leyak Essence.
- Leave or continue only after the original route objective is still viable.
The main failure is not lacking the correct item. It is carrying the correct item in a place where you cannot reach it during the encounter.
Lamp, tower, or containment?
| Situation | Use this response | Why |
|---|---|---|
| You are looting far from base | X-Ray Lamp | Portable control is the only response you can carry |
| The Leyak interrupts crafting or crate sorting | X-Ray Tower | Fixed coverage protects the place where you stand still |
| You need one more Leyak Essence for a craft | X-Ray Lamp first, tower if at base | Both can create a safe pickup window |
| The same base area keeps getting interrupted | Reposition X-Ray Tower | The protected zone is in the wrong place |
| You want long-term control | Containment Unit: 91 setup | Containment is a planned encounter, not an emergency reaction |
This choice matters because each tool solves a different risk. A tower does not help while you are deep in a sector. A lamp in storage does not protect a crafting bench. A containment unit does not replace the first portable response.
Base coverage checklist
Place X-Ray Tower coverage around behavior, not decoration. The best tower locations are places where players pause:
- Crafting Bench and repair stations.
- Labeled high-value storage.
- Co-op regroup points before a route.
- A staging room used before Security, Cascade, or Night Realm trips.
Avoid placing the tower only at the outer edge of a base because it "looks like" a perimeter defense. The Leyak is not the same problem as a physical raid. Put X-Ray coverage where interruption costs time or materials.
Leyak Essence pickup rules
Leyak Essence is useful, but it should not turn every encounter into a risky chase. Use these stop conditions:
| Condition | Decision |
|---|---|
| You need essence for a current craft | Collect it if the area is clear |
| You are carrying progression loot | Bank the route first; do not extend for a bonus drop |
| Another enemy is active nearby | Control the room before checking the floor |
| Your lamp or armor durability is low | Leave and reset instead of forcing another encounter |
| Co-op teammate called a retreat | Treat retreat as the objective; collect later |
The resource is repeatable through correct X-Ray handling. Losing a full route for one extra pickup is usually worse than returning prepared.
Containment Unit: 91 planning
Containment is a separate objective. Before attempting it, confirm:
| Check | Pass condition |
|---|---|
| Space | The Leyak can approach the unit area without trapping the player |
| X-Ray source | Lamp or tower is ready before drawing the Leyak in |
| Escape route | The player can leave if the first attempt fails |
| Inventory | Progression loot and rare materials are already stored |
| Team role | In co-op, one player is responsible for the X-Ray response |
Do not attempt containment in a cluttered storage corner. Clear a staging space first, then treat the encounter like a setup task rather than a panic check.
Common mistakes
| Mistake | Why it fails | Correction |
|---|---|---|
| Confusing Leyak with Nocturnal Anomaly | They use different materials and routes | Use this page for Leyak; use Anomaly capture for Test Tube routes |
| Carrying the lamp in general inventory | You cannot reach it fast enough | Assign one hotbar slot and keep it consistent |
| Building only physical traps | Traps do not replace X-Ray coverage | Add X-Ray Tower coverage to work areas |
| Farming essence during a bad route | The bonus pickup can cost the main objective | Bank progression loot first |
| Starting containment without space | The setup becomes more dangerous than the Leyak | Clear the unit area before the attempt |
