A prepared cave visit can collect mapped crystal while managing the separate risks of cave travel.

WHERE & HOW TO FARM
Where to farm
Cave locations with Crystal overlays on The Island resource map. Use the cave entrance and resource information to plan access as separate points.
A crystal marker inside a cave is a reason to plan a cave expedition, not proof that the interior is safe. Identify the entrance and the node location separately, bring supplies for combat and visibility, and set a clear turn-back condition. Gather the crystal only while you can still exit with your health, inventory, and equipment intact.
A light source and supplies for the planned cave trip.
Carry capacity and a known route back to the surface.
Choose a cave with mapped crystal and identify its entrance before departure.
Prepare weapons, armor, light, and supplies for the cave environment and likely encounters.
Approach the entrance and confirm that your health and equipment are ready before going inside.
Move through the cave carefully, checking the route and threats rather than rushing toward the resource marker.
Harvest accessible crystal nodes with a pickaxe when the area is manageable.
Check supplies, health, and carry weight before deciding whether to continue farther.
Leave by the route you know and return to the surface before your reserves become critical.
Farming tips
Resource nodes and cave entrances are separate map-planning questions; knowing where crystal is does not establish the safest way in.
Set a conservative turn-back point before entering, especially on a first visit.
Repeat, collect and use
Repeat the cave-to-crystal-to-surface loop when you need more material and can prepare for another expedition. This is not a guaranteed reward cache; the amount collected depends on accessible nodes.
Common mistakes
Treating the cave marker as a safety signal: prepare for cave threats and identify the entrance independently.
Continuing after supplies or health are low: turn back while you still have a safe exit.
Carrying more than you can safely take through the return route: leave when the load compromises movement.
When to stop or switch
Turn back when your health, light, supplies, or carry capacity makes reaching the surface uncertain; otherwise finish after the planned crystal load.
