The VAMPIR market sells for diamonds and charges twice: a gold fee when you list, as a percentage of the listing, and a diamond commission when it sells, as a percentage of the price. Only rare-or-higher gear, skill books and miscellaneous items and unique-or-higher boxes can be listed, and you need identity verification to trade at all. The dark trade is the other exit for items: it turns them into dark merchant coins on a refreshing list.

Market: three trading modes

Price to the net, not the listing: fee out in gold when you post, commission out in diamonds when it sells. The clan tab is the quiet bargain bin, since members list for each other, and the history tab is where you check what a thing actually sold for rather than what it was posted at.

Dark trade: items into coins

  1. Open the dark trade from the main menu and read the list; each entry shows how many dark merchant coins an item pays and how many times it can be exchanged.
  2. Tap an item to see where it drops, whether it can be crafted and what it does on the market before you hand it over.
  3. Watch the refresh time at the bottom of the screen: the list changes or expires on it.

Dark merchant coins buy things like the Bormago follower marks, which is why the collection screen warns you before you register an item the dark trade wants.

NPC shops

Entering town lights a shop shortcut in the lower right. You buy, sell inventory to the merchant, and can set a bulk purchase list so restocking potions is one tap. For a free player the NPC shop is where gold goes, while the market is where diamonds go.
