I have been merching nox last few days. Mostly i buy one bow/staff, sell it almost same price. Then buy another one below previous buy price. I make profit on my 2nd purchase. Buy limit for Nox weapons are 2 per 4 hour. I make 100K to 400K Gp per sale. Some times i make a lose when it crashes hard and lose lot of money, but its all part of learning
Today i buy a nox bow for 212,200 K GP, sold for 224 M GP.
