Creatures must make a Wisdom save to notice a specific, small item magically guised on your person.

An object you touch, smaller than 1 cubic foot, blurs into insignificance. For the duration of this spell, any creature that searches someone concealing that item must make a Wisdom saving throw. On a failed save, the creature fails to notice the item, and cannot make an ability check to find it. On a success, the creature is immune to the effect of this cantrip on that item for 24 hours and may make an appropriate ability check to find the item. If the concealed object is threatening or out of place, the creature has advantage on this saving throw.

If you cast this spell multiple times, you can affect up to three objects once each, and you can dismiss such any or all of these effects as an action.
