Elementium Ore is the higher level of the two Cataclysm ores. It can be farmed in Deepholm, Twilight Highlands and Uldum.
Twilight Highlands is often the least farmed area for this. Deepholm can vary based on the server. Uldum tends to attract many bots and is often very over farmed.
You can also farm the following gems and elementals from elementium:
- Volatile Earth
- Volatile Air
- Inferno Ruby
- Ocean Sapphire
- Dream Emerald
