As the artifact’s seller made sure to point out in his auction listing, if you used the tablet’s power in conjunction with the Scoreboard, it arguably became the most valuable artifact in the entire OASIS. All you had to do was watch the top rankings on the Scoreboard and wait until someone’s score increased. The second that happened, you could write that avatar’s name on the tablet and it would tell you where they were at that exact moment, thus revealing the location of the key they’d just found, or the gate they’d just exited. Due to the artifact’s range limitations, it might take two or three attempts to narrow down the exact location of a key or a gate, but even so, that was still information a lot of people would be willing to kill for.
