[@BBeast] I seem to remember that it only detects divines who are within its proximity. Is that still so? Does it ignore concealment levels? (So for instance, if Teknall had had it pre-Realta when he visited Yara, would it have detected Vowzra and Yara?)

This gem was a prototype of Lazarus', not the final design, so it is probably not as effective as the final product. Additionally, the purpose of this gem was not to function as a divinity detector (as that would require the rest of the machinery which went with the gem), but as a record of what a background level of divinity is. It was the data which was most valuable, not the gem itself.

That said, if Teknall ever needs to create a mechanical divinity detector, then he'd re-purpose that gemstone and copy the design of machinery it originally came in.
