This is a guide for people who would like to farm Fel Iron ore, and also level up mining from 300-375.
The best place to farm Fel Iron is in Hellfire Peninsula. Nodes no longer spawn near the Dark Portal. Here's a map of my route to farming Fel Iron. The more concentrated "Spots" for farming are circled.
