This sparkling diadem is made up of tiny glass orbs that resemble cataracts but are in fact reified thoughts. When you activate this diadem by thought, you can detect the thoughts of every sentient mind in a melee space around you. Each activation lasts ten minutes per strength of the item, and you must concentrate on a single mind per round to discern their thoughts from the cacophany of others. Subjects think in their own language, and there can't be more than 3 inches of solid stone or metal in between you and the minds you attempt to read. Only if a subject becomes aware of your telepathy are they entitled to a Psionic spell check to resist your mind reading.
