Sandustry Anomaly & Tier 5 Guide

Anomalies are rare events in Sandustry that interrupt the peaceful digging-and-building loop. They escalate through five tiers, and the Tier 5 anomaly is the endgame investigation that tests everything your factory can produce.

Early Access note: anomaly behaviour changes with patches. Treat this as a framework and confirm current details on the official wiki.

What anomalies look like

Anomalies appear as unusual activity in the terrain — they stand out from normal sand and materials. The longer you ignore one, the more it escalates. That escalation is what the tier system tracks:

• Tier 1–2: early signs; low impact, mostly a warning.
• Tier 3–4: the event grows; it starts interfering with production and needs attention.
• Tier 5: the full anomaly — the hardest investigation, with the best rewards.

Investigation checklist

Work through the anomaly systematically instead of improvising:

1. Locate it. Mark the area and note what type of activity it is.
2. Check your production. A Tier 5 investigation can consume serious resources — your factory needs to run unattended while you focus on the event.
3. Gather the required materials. Keep buffers full; the anomaly may demand rare outputs (materials such as Amethelis are often involved in endgame content).
4. Follow the event steps. Escalation events in Sandustry reward steady progress, not rushed actions.
5. Collect the reward. Tier 5 rewards are the reason endgame players farm anomalies.

Preparing your factory for Tier 5

• Automated power: the event can run long; your power chain must not need babysitting (see Florin & Florinol).
• Storage buffers: full Collectors everywhere, so the factory survives an hour of neglect.
• Rare materials stockpiled: know what the anomaly asks for before it asks.

Common mistakes

• Ignoring early tiers — every ignored anomaly escalates; deal with signs early.
• Under-preparing — walking into Tier 5 with a starter factory wastes the event.
• Guessing requirements — check the official wiki for the current anomaly recipe before starting.
