Flowstone

Access to Overworld ores is via the Flowstone mod. Flowstone makes Stone generators produce ores.

• The generator must produce Stone, not Cobblestone.
• The ores will generate with a frequency proportional to their world generation occurrence rate at the Y level and biome where the stone is generated. See also: Ore Distribution
• The ore frequency can be increased by placing Magma Blocks within a five block cube around the block being generated. With no magma, ore generation is rare but still useful; with maximum magma, more ores will be generated than plain stone.
• Stone generators for Terrestria's Volcanic Rock will produce Volcanic Rock, but ores produced will be vanilla stone ores.
