Ring of Names

When you shake hands with a humanoid while
wearing this brass signet ring, you can make a
Wisdom (Insight) check contested by the target's
Charisma (Deception) check. On a success, the
target's name becomes engraved on the ring,
which you magically learn. The written name is
the one that it would be willing to share with a
casual acquaintance. The creature is unaware of
this effect. This property of the ring can't be
used again until the next day. Only one name can
be engraved at a time
