What makes this cave different

These caverns replace familiar stone with galena and giant neodymium crystals. Scarlet neodymium attracts metal objects while azure neodymium repels them, making iron and netherite equipment a tactical consideration.

What to look for

Look beyond ore veins: glowing galena, Tesla Bulbs and abandoned extraction sites are all worth investigating. Tesla Bulbs can discharge damaging electricity.

How to prepare

Carry a non-metal backup loadout, watch your movement near crystals and avoid striking Tesla Bulbs at close range. Scout from the edge and mark a clear exit.

Resources and rewards

Neodymium, galena and materials for magnetic equipment and mechanics.
