Five-second answer

In Moonlit Pines, break the large entrance boulder with a Copper Pickaxe. Upgrade to an Iron Pickaxe before trying to mine Rose Quartz or Moon Crystal nodes inside.

Before you go

Prerequisites

  • Upgrade the Rusty Pickaxe to Copper at Howling Hammer.
  • Bring food or enough energy for mining.
  • Plan an Iron upgrade if you need actual crystal drops rather than entry alone.

When it does not work

Common blockers

Copper opened the cave but the crystals will not break.

This is expected: the entrance requires Copper, while the crystal nodes require Iron.

Rose Quartz is not counting for my quest.

Confirm the correct quest is active, the item reached your inventory, and the requested total is complete before returning to the NPC.
