Mercer Spheres are placed alien artifacts collected at world locations shown on the map. They are not manufactured from a recipe. Each placed sphere is a one-time pickup; the site does not track collected state, so use the map as a locator and verify availability in your own world. The practical bottleneck is reaching an uncollected location safely, rather than a production rate. The artifact's description presents it as an unusual alien phenomenon; this guide focuses on finding and collecting its placed world instances.

How to farm

Use the on-page map to locate Mercer Sphere markers and travel to a shown location. The map identifies locations but does not provide a guaranteed route or confirm whether you have already collected a sphere.

Before you go

  • Map access and a route to the selected location.
  • Inventory space for the collectible.
  • Equipment and supplies suitable for the trip.
  1. Open the map and locate a Mercer Sphere marker.
  2. Choose a location that fits your current travel and safety needs.
  3. Travel to the marked area and search nearby for the placed artifact.
  4. Approach and interact with the sphere to collect it.
  5. Check your inventory to confirm pickup.
  6. If the marker remains on the site map, remember that collected state is not tracked and do not assume the sphere respawned.

Farming tips

  • Placed collectibles do not respawn as a route for repeated gathering.
  • The map can guide exploration, but it cannot confirm which artifacts you have already collected.
  • Plan for hazards and terrain around the location before committing to the trip.

Repeat, collect and use

Repeat with another marked location when you want to collect another placed sphere; each is a separate pickup. Use your in-game inventory and exploration history to avoid revisiting collected locations.

Common mistakes

  • Expecting the same collected sphere to respawn for repeat farming.
  • Assuming the site removes a marker after collection or tracks your personal collected state.
  • Assuming the map marker supplies a safe route to the artifact.

When to stop or switch

Stop searching a location once the artifact is collected or the marked spot is confirmed inaccessible in your current session.
