Gem of seeing

This lenticular faceted gem is indistinguishable from an ordinary jewel in appearance. When it is gazed through, a gem of seeing enables the user to see as though she were affected by the true seeing spell. A gem of seeing can be used for as much as 30 minutes a day, divided up into periods of minutes or rounds as the user sees fit.

Peering through the crystal is tedious and time-consuming. The gem does not enable the user to passively notice revealed things, only to scan for them actively. It takes one round to scan a “quadrant” (a 90° arc, out to the the effect’s maximum range of 120 feet). Focusing one’s vision to see into the Ethereal Plane likewise takes a round for each quadrant scanned.
