Nocturnal Anomaly guide: Collection, trading, and farming

Collecting, Trading, and Farming the Nocturnal Anomaly

What Is the Nocturnal Anomaly?

The Nocturnal Anomaly (IS-0299) is a night-only entity with fixed spawn locations. It does not attack directly but responds to light—becoming transparent when illuminated. You can still collect material from its transparent form by right-clicking its previous location. Carrying empty Test Tubes during night travel significantly improves capture success; without one, the chance is extremely low.

Collecting Anomaly Material

The primary resource from the Nocturnal Anomaly is Anomaly, a component used in trading and farming. Anomaly decays over time from "warm loss" (like Mug of Coffee), leaving an empty Test Tube. Store it in appropriate containers to prevent decay.

When to collect: Only during night cycles. Plan routes near known spawn points before nightfall.

Prerequisites:

• Empty Test Tubes (at least 3)
• A light source (any will do—no special lamp required)
• Quick reflexes: the entity disappears when lit, so right-click immediately

Stop condition: If you miss the collection window, the entity returns later the same night. Do not chase it into dark areas without preparation.

Trading Anomaly

Anomaly can be traded with three NPCs. Choose based on your current needs:

Tradeoff advice: Rebar is the most efficient trade early on (1:1 ratio). Partial Organs are useful but cost 3 Anomaly—only trade if you have surplus. Tacos are expensive; avoid unless you have excess Anomaly and need food.

Farming with Anomaly: Tiered Plant Food

Anomaly is used to craft three tiers of plant food. Each tier improves growth rate and reduces water consumption, but the gains diminish significantly after Tier 1.

Tier Comparison

Key insight from sources: The biggest jump is from no fertilizer to T1. T2 adds only 5-10% growth and 10% water reduction over T1. T3 adds another 20-25% growth and 35-40% water reduction over T2, but requires more Anomaly.

Practical advice:

• Start with T1 for general farming. It's cheap and gives the most benefit per Anomaly spent.
• Use T2 sparingly—only for crops you need urgently or in dry conditions.
• Reserve T3 for high-value plants or when you have excess Anomaly. The marginal gain over T1 is moderate, not transformative.

Recovery tip: If you accidentally apply fertilizer to a fully grown plant, it has no effect but remains on the plot until a new plant is placed. Don't waste it—just plant something new.

Night Collection Workflow

1. Before nightfall: Check your inventory for empty Test Tubes (at least 3). Equip a light source on your hotbar. Identify nearby spawn locations from memory or map.

2. During night: Travel to spawn points. When the entity appears, shine your light on it immediately. Right-click its previous location to collect Anomaly. If you have a Test Tube, capture chance is high; without one, it's very low.

3. If you miss: The entity returns later the same night. Wait in a lit area and try again. Do not chase it into dark zones.

4. After collection: Store Anomaly in a container to prevent decay. Check periodically for "warm loss" status.

Common Mistakes and Recovery

Mistake: Trying to fight the entity The Nocturnal Anomaly does not respond to weapons. Physical attacks are wasted. Recovery: Use light only. Retreat to a lit area if overwhelmed.

Mistake: Forgetting Test Tubes Without a Test Tube, capture chance is extremely small. Recovery: Return to base, grab Test Tubes, and wait for the entity to respawn later that night.

Mistake: Overinvesting in high-tier fertilizer T2 and T3 cost more Anomaly but offer diminishing returns. Recovery: Stick to T1 for most crops. Only upgrade for specific needs (e.g., speed-growing rare plants).

Mistake: Ignoring decay Anomaly decays like hot coffee. Recovery: Store in containers immediately. Check stored materials regularly.

Final Tips

• Anomaly stacks to 32 and weighs 0.2 each—manage inventory space.
• The entity's spawns are static; learn them for efficient farming.
• T1 compost is the most resource-efficient fertilizer in the game. Don't feel pressured to craft higher tiers unless you have surplus Anomaly.
