How much is the tax when selling an item in Knight Online?

A 3% tax is taken on every sale made in the Moradon market and the seller pays it. When an item you listed at 100 million coins sells, you get 97 million coins. The tax doesn't change by item type; whether you sell a weapon or armor the rate is the same. Items that change hands by trade have no tax.

How do I find the item I'm looking for in the market?

In game you have to open the stalls one by one; reading the stall titles and checking the ones that look relevant is the most practical way. The faster way is to learn the item's price range from the listings outside first, then look for a stall under that range in game. If you roam the market without knowing the range you can't tell whether the price you find is cheap or expensive.

Can a locked item be sold?

No. A locked item can neither be put in a stall nor traded. If you're selling you have to unlock it first. If you're buying, asking during negotiation whether the item is locked heads off the problem at the delivery stage.

Why is the same item a different price on every site?

Sites get their listings from their own users, so each site's supply is different. One site may have three listings of an item while another has thirty; the supply gap shows straight in the price. The site's own commission goes on top too. That's why looking at one site almost always means overpaying.

What's the most expensive item in Knight Online?

There's no fixed answer, because the top of the list changes by plus level and server. High-plus weapons are usually at the top, but to see which listing is the most expensive right now just sort the item prices page by price — the real listings of the moment are there.

Is it smarter to sell the item or sell GB?

If the item you have is really in demand, selling it as an item usually brings more, because buyers come looking for that item. If it's an ordinary item, converting it to coins and selling as GB is faster. Before deciding, look at the item's listing price outside and the current GB rate and compare the two routes in the same currency.

How to sell items in Knight Online, and where to buy them

First separate this: there are two markets

When people say "item market" in Knight Online they mean two different things, and the rules differ. The first is the game's own market: you open a stall in Moradon and sell the item for coins, the trade ends inside the game. The second is broker sites outside the game: they buy and sell items for TRY; delivery still happens in game but the money moves through a bank.

The same item's value differs in these two places. In game you talk in coins, outside in TRY. The bridge between them is GB: if you know how many GB the item is worth, you can work out the item's TRY value from the current TRY rate of GB.

That's why the price question can't be answered on its own. Before asking "how much is this item" you need to fix which market you mean and which server you're on; the same item doesn't go for the same price on Zero and on Felis.

Selling by opening a stall in game

Go to Moradon. The market area is the crowded part of the town; stalls are set up there.
Keep the item you'll sell in your inventory. Equipped items can't be sold, you have to take them off first.
Open the stall, place the item and write the price in coins.
Give your stall a title. Put the item's name in the title — players browsing the market search by reading stall titles.
Keep your character in game until it sells. The stall closes when you log out.
When the sale happens the 3% tax is taken automatically. You get 97% of the price you wrote.

Why searching the market is hard

Hundreds of stalls stand side by side in the market and you have to open each one. Even if the item you want is in someone's stall, if its name isn't in the stall title it's hard to find.

In practice players do this: first read the stall titles and open the ones that look relevant, and if that fails, roam the other corners of the market. If what you're looking for is a rare item, this can take hours.

The shortcut: look at the listings outside to learn the item's market range, then look for a stall under that range in game. If you roam the market without knowing the range you can't tell whether it's cheap or expensive — you have nothing to compare against.

What item locking means

Locking means making the item unsellable and untradeable. A locked item stays on your character; it's used as protection where there's a risk of losing it.

The part that matters for trading: if the item you're buying is locked, it can't be transferred to you. Asking "is the item locked" during negotiation heads off the problem at the delivery stage.

Likewise, if you left the item you're selling locked you can't put it in a stall. You have to unlock it before selling.

The current TRY value of GB

Buying an item from a broker site

Pick your server. An item on another server can't be transferred to you; this is the most common mistake.
Compare the same item on more than one site. The gap isn't small; it can be hundreds of TRY.
Check the listing's plus level. A "+8" item and the same item at "+0" are completely different things, and so are their prices.
Check whether the listing is really still open. A sold listing that hasn't come off the page is very common.
Pay, and type your character name letter for letter.
Take delivery in game and don't log your character out until it's done.

What sets an item's price

Plus level. As the upgrade level rises the price grows in steps, not linearly; the gaps between the upper levels are multiples of those between the lower ones.
Server. The same item is worth one thing on an old, crowded server and another on a newly opened one.
Supply. How many listings are open at the same time pulls the price straight down.
How useful the item is. A weapon that's actually used in the game and a showcase item don't see the same demand.
The GB rate. Because the TRY price outside is worked out through GB, if GB falls the item's TRY price falls too.
Event periods. While an event that drops certain items is open, the supply of that item rises and its price slides.

The most common traps

Looking at one site. An item bought without comparing almost always means extra money.
Skipping the plus level. If the listing title doesn't say the plus, you have to ask; what you think is "the same item" can be something else entirely.
Not accounting for the tax. From an item you list at 100 million coins in the market you get 97 million.
Picking the wrong server. This is the hardest mistake to fix once payment is made.
Handing over goods first to someone you don't know. There's no protection in a trade; both sides should put in at the same time.
Rushing. The number of listings changes during the day; waiting a few hours can make a real difference.

This site doesn't buy or sell items. It regularly collects the listings of five separate listing sites and puts them side by side in the same table; which item is listed at what price on which server, how many listings there are, how big the gap between sites is — all on one screen. Which site you work with is your call.
