Fast answer

Current 0.5 guides place the main Phantom Quartz route in the caves around Gnarly Bark. The reported chain is Phantom Quartz → Crushed Quartz at the Quern → Fire Brick analysis → Quartz Glass at the Kiln. Verify exact ingredients before a large farm run.

Do this first

Save-safe order

  1. Prepare for Gnarly Bark cave threats and mark the entrance.
  2. Mine Phantom Quartz and reserve a stack for progression.
  3. Check the Crushed Quartz recipe at the Quern.
  4. Follow the Fire Brick analysis unlock shown by the current build.
  5. Confirm the Kiln recipe before converting the full stock.

01

Where players are finding it

Recent August guides and player questions point to the cave route around Gnarly Bark. The region contains dangerous creatures and vertical paths, so make the first trip a marked reconnaissance run.

02

Material chain

The cross-checked chain uses multiple stations and an analysis unlock. Keep some raw material until each station screen is verified in your build.

  • Phantom Quartz: mined resource
  • Crushed Quartz: Quern processing
  • Fire Brick: intermediate and analysis trigger
  • Quartz Glass: Kiln-crafted material

03

No unsupported respawn promise

Community posts show multiple harvest spots, but do not establish a stable respawn timer. Mark deposits and record build/time if testing; this guide does not promise a schedule.
