Metallic Tsunamis

… has confirmed that the lava oceans on … contain exceptionally pure forms of almost every known rare metalloid in our elemental catalog. This concentrated collection of liquid metals gives rise to highly volatile electromagnetic fields, causing the frequent formation of molten metal tsunamis. Using predictive modeling, we have identified brief but regular lulls in wave intensity which can be used to harvest these uniquely rich deposits.

The command below will trigger the "Metallic Tsunamis" event in Stellaris:

When this event fires, you can choose between the following option:

• Fascinating.
  • Add deposit: +2
