How do movement symbols on Artifact cards work?
Quick answer
Artifact cards don't have a general "movement" symbol as such — the closest matches are the travel value icons (used to pay costs) and the "relocate" keyword, which moves your archaeologist without a travel cost.
Details
Cards in your hand can generally be used either for their effect or for their travel value — a printed icon (compass, coin, tablet, arrowhead, or jewel) that can be spent to cover the travel cost of actions like Dig at a Site [p.8 — Your Hand] [p.9 — Dig at a Site]. Higher travel values can always substitute for lower ones according to the Travel Hierarchy printed on your reference sheet [p.9 — Dig at a Site]. However, artifacts you buy go straight into your play area rather than your hand, so they are normally used for their effect rather than spent for travel value [p.12 — Buy a Card].
Some artifact effects move things around the board rather than functioning as a generic "travel" icon. The keyword relocate lets you pick up one of your own archaeologists that is already on a discovered site and move it to an unoccupied space on a different discovered site, with no travel cost paid — some cards add extra restrictions on where it can go [p.24 — Keywords]. This is different from an action effect (like the "dig/discover" icon), which still requires paying a travel cost and starts from your player board, not from a site [p.23 — Frequently Asked Questions].
A few specific artifacts affect the movement of guardians rather than archaeologists — for example, Guardian's Crown can move a guardian tile, but only to a site that has already been discovered and is otherwise unoccupied [p.22 — Notes on Selected Cards].
Watch out: Don't confuse the "relocate" keyword with the action-icon effects (which let you take a full Dig/Discover action as part of a card's effect). Relocate never requires paying a travel cost and cannot target an undiscovered site, while action-icon effects follow all the normal rules of that action, including travel costs [p.23 — Frequently Asked Questions].
