Sentinel's Data Gem

This crystalline orb shimmers with an inner light, its surface reflecting shifting images of ancient texts and scholarly figures. When held, the Sentinel's Data Gem allows the wielder to tap into the residual psychic energy of the Archive. You may use this gem as an arcane focus. Once per day, you can cast the spell Identified without expending a spell slot. Additionally, if you are in a location that contains arcane writings or magical records, you can use a bonus action to gain advantage on your next Intelligence check or Intelligence saving throw. If you fail, the gem will drain its energy and cannot be used again until the next dawn. Requires attunement.
