Anomaly capture: Test Tubes, nocturnal spawns, and the IS-0059 Reaper

Field Complaint

Anomalies keep showing up and I have no idea what to do with them. Can I capture them somehow?

Validated Response

Yes, and you should — captured anomalies feed the Immurement Registry and unlock crafting progress. Craft Test Tubes from Glass Scrap and Wood Plank, then walk up to an anomaly with a tube equipped and press Interact. No fighting required for most of them. Nocturnal anomalies only appear at night, have static spawn locations, disappear in bright light, and eventually expire if you ignore them — so carry empty tubes when the sun goes down and learn their spots. The IS-0059 Reaper is the big one: a black-cloaked figure with scythes that patrols the Security Sector. Kill it with an Energy Pistol (1 to 3 shots) or hit it with an X-Ray Lamp to make it drop Night Essence. Lodestone Bolts also work if you have the crossbow setup. Night Essence is a key crafting material for late-game recipes and Nyxshade Seeds, so the Reaper is worth hunting repeatedly. Plan your capture routes before nightfall — knowing which anomalies you need for which recipes prevents wasted tube slots and missed spawns.

Summary

Anomalies are collectible entities used for advanced crafting. Carry empty Test Tubes at night and plan your hunting routes in advance.

Prerequisites

• Craft Test Tubes from Glass Scrap plus Wood Plank
• Learn the nocturnal anomaly spawn locations
• Prepare crafting recipes that need anomaly materials before hunting

Recommended Loadout

• Empty Test Tubes (carry several at night)
• X-Ray Lamp for IS-0059 Reaper encounters
• Planned route through known anomaly spawn points

Step-by-Step Route

1. Craft enough Test Tubes for a night's hunting run
2. Travel at night when nocturnal anomalies spawn at their static locations
3. Walk up to an anomaly with a Test Tube in hand and press Interact to capture
4. If you see a nocturnal anomaly, grab it immediately — they expire after a while and disappear in light
5. For the IS-0059 Reaper in the Security Sector, use the Energy Pistol or X-Ray Lamp to get Night Essence
6. Check the Immurement Registry to track which anomalies you have collected
7. Use Lodestone Bolts on the Reaper for guaranteed essence drops — Shock Bolts do not work

Common Mistakes

• Walking around at night without empty Test Tubes and missing capture opportunities
• Trying to fight the IS-0059 Reaper with standard melee — it is far more efficient to use Energy Pistol or X-Ray Lamp
• Collecting anomalies without having the downstream crafting materials ready
