Wand of Extraction

Once per day, as an action you may choose a
creature within 120 ft. The target must make a
DC 15 Wisdom saving throw. On a failed save,
you gain a general idea of the creature's combat
capabilities as compared to your own. At the
DM's discretion, you may learn about other
pertinent capabilities. The target is unaware of
both the casting and being targeted by the spell.
The wand's insight refreshes every day at dawn.
A creature that saves is immune to the effect for
24 hours.
