1. Buy all icethorns and lichblooms that are under 20g per stack or get yourself some suppliers that will sell you herbs for lower prices than AH.
2. Mill them.
3.Make Ink of the Sea and Snowfall Ink.
4.Sell them on AH (I'm selling both by stacks of 20)
5.Enjoy your easy gold.
I went from 1500g to 4000g in 1 day. I'm the only one on my server who sells is doing this so I get a lot of gold from this.
I searched and I think that it hasn't been posted.
