It works by using fc to find harm rune worlds for the hour and try to keep constantly mining. It mines alot faster than normal rune.
You use porters, lava titan with either perfect juju mining or 2x loot ramhammer. Using ram with juju bugs and loses the extra ore. You can also use smelt prayer to instacook the corrupt ores you get for a little smith xp although I dont bother.
You also dont mine non-harmonised west rock cos it cant harm from a dead rock.
