* A fairly reliable source of the ore is through Magma and Omni geodes on lower mine levels. These can be obtained frequently by mining all rocks on the mine levels 115-119. To further enhance geode frequency, choose the Geologist skill at [[mining]] level 5 and the Excavator skill at [[mining]] level 10. With both skills chosen, you can obtain ~20 geodes from each pass of mining all rocks from level 115 down to 120.
