Leyak Phantom and X-Ray Lamp: safe response, tower coverage, and containment

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:

1. Where is the X-Ray Lamp in your inventory?
2. Which base area has X-Ray Tower coverage?
3. Are you farming Leyak Essence, escaping pressure, or setting up containment?

Confirmed response tools

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.

The tower and lamp have separate unlocks. Examine the emitter outside the Leyak cell for the tower recipe; the lamp recipe comes from the X-Ray Shield Emitter panel at the Control Center entrance after the Furniture Store escape. Keep the portable lamp charged. Before it is unlocked, unobstructed staring can repel the Leyak, but it is not the Essence-producing X-Ray method.

Field response workflow

Use this sequence any time Leyak pressure is active away from base:

1. Put the X-Ray Lamp on a consistent hotbar slot before leaving.
2. Keep one clear retreat line instead of running deeper into unknown rooms.
3. When the Leyak appears, stop sprinting blindly and face the threat.
4. Use the X-Ray Lamp long enough to force the response.
5. Confirm the area is safe before checking for Leyak Essence.
6. 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?

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.

Tower placement by base type

The Leyak page excludes Security Sector and Portal Worlds other than Rise and The Pool Room. Do not build a tower in Night Realm to counter an encounter that does not occur there. The tower reference confirms activation within its reach, including through walls; it does not establish that one tower covers every room or that every large base needs exactly two. Check power and actual response at each work point when an encounter occurs. Seeing the tower from a station alone does not prove that station is covered.

Leyak Essence pickup rules

Leyak Essence is useful, but it should not turn every encounter into a risky chase. Use these stop conditions:

The resource is repeatable through correct X-Ray handling. Losing a full route for one extra pickup is usually worse than returning prepared.

The Essence page distinguishes an untouched fresh drop from a collected item: radiation starts after pickup. Use radiation protection while carrying it and store it in an unlocked GATE Security Crate or Hazard Crate, not an ordinary nearby supply box. Do not consume it. If storage is not ready, leaving a fresh drop is safer than collecting it and assuming that throwing it back down removes the hazard.

Containment Unit: 91 planning

Containment is a separate objective. Before attempting it, confirm:

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.

The Containment Unit: 91 reference requires power and continuing Greyeb upkeep for Leyak containment. Watch the resource bars and alarm; a unit left unpowered or depleted permits escape. Essence drops from the chute at 6 AM each game day while containment holds. This is maintained control, not a permanent one-time cure.

In co-op, the Leyak reference says only the targeted player normally sees the entity. Let that player handle the visible threat and call the position; the rest of the group can clear clutter, check power, and prepare storage without assuming everyone shares the same view.
