Farming tips
- Rich Thorium is the best source of Arcane Crystals, keep them for Arcanite or sell them.
- The Burning Steppes and the Plaguelands have Thorium too when Un'Goro is crowded.
What it is used for: Thorium Bars for endgame Blacksmithing and Engineering, Arcanite, and the new Heavy Thorium that only a miner's Molten Foundry can smelt.
How much you get per hour
We measure real amounts per hour on the live realms in launch week and add them here. Until then the map shows how dense the nodes are and the table the drop rates.
In the first weeks after launch
