Basically you get the NW pots from hitting the chest after killing a Legacy guardian in NW. There are different ones although I dont know their names.
Defense Rate +1200 (blue)- sells usually for 800K for a stack of 7 Flee rate 90% (black)- a stack sells for 2 mil Sword amp 15%- a stack sells for 2 mil Magic amp 15%- stack sells for 1 mil Attack/ Magic +50- Sells for 200K
The rest really dont sell.
These are the prices that I sell them around. So if you pick up about half the NW pots in NW you should make around a good 4-6 mil per NW, counting the Core cube. =D and well this is it. Hope it helps you people >.<
