sorry if this already been posted but ithought i would share it with you just incase it had not
I noticed as I was walking through Nagrand the other day that there is a vendor in halaa that you can buy green weapons from. I saw that the thrown weapon he sells only costs about 2g so i thought i would buy 1 and see what it DE'ed into, much to my suprise i got 2 Greater Planar Essence which sell for around 8g each on this server. so if ya wanna make some extra cash while ya farming in nagrand just pop by halaa when ever it is in control and buy all the thrown weapons that he sells and you should make around 36g worth of Planar essence each time you do it because he only 3 in stick at a time.
