'''Building cost:''' 10000 {{G}}.<br>'''Buildings required:''' [[Marketplace]].<br>

'''Artifact Merchants''' is a building that can be constructed in [[Tower]], [[Dungeon]], {{swh|[[Conflux]], and [[Factory]]{{-wh}}| and [[Conflux]]|noicon=}}. It enables visiting heroes to buy or sell [[artifact]]s. The set of artifacts available for sale are the same in every merchant, regardless of the town, the town type or the player. The available artifacts contain three [[List of artifacts sorted by class#Treasure artifacts|treasure artifacts]], three [[List of artifacts sorted by class#Minor artifacts|minor artifacts]], and one [[List of artifacts sorted by class#Major artifacts|major artifact]]. Once an artifact is purchased, it is gone from all artifact merchants. At the beginning of each month, the set of artifacts available for sale is renewed.

The [[adventure map]] equivalent is the [[Black Market]].

== Price of artifacts ==
Every artifact has a so called [[basic cost]], from where the sell price and the buy price is determined. The price depends on how many [[marketplace]]s the player owns. The rule of thumb is, that the more marketplaces, the cheaper are the buy prices and the higher are the sell prices. For example, with four markets, a [[Ring of Life]] with a base cost of 5000 can be bought for 14286 gold, or sold for 1750 gold.

PRICE (sell) = B &times; (1 + (M - 1) &times; 0,25) / 5

  where   B = basic cost of an artifact
          M = number of marketplaces (max. 9)</pre>

===Exploit===
If the player owns zero marketplaces, but accesses an artifact merchant through a town owned by an ally, artifacts can be bought at a price of zero gold. This is fixed by the [[Heroes 3 HD|HD mod]] and {{hota}}.
