DNF's current price of high-strength weapons is basically like this. Starting from+1 1, the price will basically double every time it is strengthened. +1 1 scaffold is basically stable at about 2500W W ..+12 is 5000W,+13 is 1E, 14 is 2E, 15 is 4E. It's about 15000 RMB. This is a price that is more in line with market rules. However, because an artifact as strong as 18 is hard to find in the game, items that belong to the highest level in a server are really valuable. In this case, it is no problem to ask for 4W and 5W RMB.

I wish you a happy game and hope to adopt it.
