So recently on azgalor the enchanting mats market has taken a tank. I think large prismatics are going for around 13g or less. I was thinking this morning about what mats I could save up to try and get a jump on enchanting.

According the this it goes green at 400. I am going to try to get around 50 void crystals saved up to power enchanting from 375-400+. Something to think about with the expansion not far away.
