How to farm Arcane Crystal

Mine Thorium deposits for a chance at Arcane Crystal. Use the Thorium Ore route; the crystal is a rare bonus, not a separate vein. In original Classic there is no Jewelcrafting prospecting.

Classic Era, TBC and Wrath use the original Azeroth terrain. Cataclysm and Mists use the reworked world, so use a route for your realm’s terrain.
