Trifold Goddess's Amulet (Nightfell)

The caster draws strength from lunar energies to transmute the material component in a replica of Mirithlen’s own necklace. The item displays a flaunting amethyst and can be worn or held to have Advantage on the next Intelligence (Investigation), Wisdom (Insight) or Wisdom (Perception) checks, if based on sight. When all three checks are made, the effect ends even within duration. When the spell ends, the item turns back to its original look. Only one item at a time can be enchanted by the same caster.
