When does the Dark Trade list refresh?

  1. Open Dark Trade from the main menu. Each entry shows how many dark merchant coins an item pays and how many times you can exchange it.
  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. Check the refresh timer at the bottom of the screen. When it hits zero, items get swapped out or their exchange closes.

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

Short answer

VAMPIR's Dark Trade list changes on its own timer, shown at the bottom of the Dark Trade screen. On the Japanese (Global2) servers the phase-two items arrived with the September 21, 05:00 refresh. Also: market fees, what you can list and what NPC shops are for.

What changed in Dark Trade on September 21?

Netmarble's September 16 update opened Dark Trade phase two for the Global2 region, the servers run in Japan. The new exchange items went live at the September 21, 05:00 list refresh (KST/JST). Installing the patch didn't add them; the refresh did. Players on Korean and Global servers don't get this phase.

Dark Trade phase two, Global2 servers
StepWhat you do
1. Seal Buy the Dark Merchant Seal in Shop → Exchange → Diamonds
2. Certificate Craft a Dark Merchant Certificate; the seal is one of its ingredients
3. Dark Trade Exchange the certificate for Dark Merchant Gold Coins
4. Spend Shop → Exchange → Dark Merchant Gold Coin tab

The gold coin is its own currency, not regular Gold. Work backwards from the reward you want: check its coin price, then how many certificates that takes, before you start buying seals.

Diamond farming starts at 0:40, the summon safety net at 2:15.

How much does the VAMPIR market take?

Market rules in the Korean guide
RuleDetail
Buying Diamonds
Listing fee Gold, a percentage of the listing amount
Commission Diamonds, a percentage of the sale price
Trading modes in the Korean guide
ModeHow it works
Public Buy others' listings with Diamonds; sell tradeable items; the listing closes after a set period
Personal Sell to a named player; needs Olga's Grace; fee plus a deposit you get back if it doesn't sell
Clan Buy what clan members have listed

Price to the net, not the listing: the fee comes out in gold when you post, the commission in Diamonds when it sells. The clan tab is the quiet bargain bin, since members list for each other, and the history tab shows what something actually sold for, not what it was posted at.

What are NPC shops for?

Walking into town lights a shop shortcut in the lower right. You buy, sell your junk to the merchant, and can save a bulk purchase list so restocking potions is one tap. For a free player, the NPC shop is where gold goes; the market is where Diamonds go.

FAQ

Why can't I list an item on the market?
You need identity verification first, and only rare-or-higher gear, skill books and miscellaneous items plus unique-or-higher boxes can be listed. Character-bound items can't be listed at all.
How far back does market history go?
The history tab keeps your last 200 trades, visible for 14 days.
Do Dark Trade coins survive a server transfer?
Yes. Netmarble's September transfer notice lists dark merchant coins and your Dark Trade exchange status among the records that move with you. Market trade history doesn't.
