The Artifact Merchants is a building available for the Tower, Dungeon and Conflux factions in Heroes of Might and Magic III. It sells random artifacts for a price. It requires the marketplace to be built, and it is not a prerequisite for any other structure. It costs 10,000 gold to build. The range of artifacts changes on the first day of each month. The initial purchase price is equal to five times the base price of the artifact, but is reduced with every market that the player owns.
