I made this Empyrium farming guide to help out players who want to farm the ores instead of buying them from the Auction House. You can mine this ore from skill 1, you will get the same number of ores as if you had Mining 100.
Empyrium
Get a [Stonehide Leather Barding] because there are so many mobs at Argus, you simply can't avoid them while farming.
If your class has a tanking spec, you should switch to that while farming, so you won't get dazed and you don't have to use Stonehide Leather Barding.
You should also enchant your gloves with [Legion Mining].
Antoran Wastes
Felfang Basilisks at Antoran Wastes drop 3-6 ore when you mine their corpse. This is currently the best way to farm Empyrium. The Basilisks are all in the green lava that does a lot of damage if you walk into it. Fortunately, there are a lot of rocks there so you have to try to jump from rock to rock without touching the lava.
