Measure

Divination cantrip (sorcerer, warlock, wizard)

Casting Time: 1 action
Range: 120 feet
Components: V
Duration: Instantaneous

Upon casting this spell, you choose an area of up to 40 cubic feet that is within range. You instantly determine the height, width, diameter, weight, temperature, or similar measurement of an object, group of objects, or similar collection of objects (like the volume of a patch of soil or pool of water) that are within the area. The spell cannot handle extremely precise or large measurements. For example, measure cannot be used to measure the exact weight of a grain of sand, or to determine the width of an odd non-euclidian object or similarly strange magical occurrences. In addition, the spell always fails when cast inside of a pocket dimension (such as those of a portable hole and similar items).

A creature knows when measure is cast on them or objects on their person, including when it is only a part of a wider area or group of objects being measured.

The creature may make a Charisma saving throw to resist the spell, being excluded from the result on a successful save. Creatures of Intelligence 3 or lower automatically fail this saving throw.

Detecting Counterfeit. This spell may cause certain acts of trickey, such as attempts to pay with fake money, to instantly fail unless the deceiver has accounted for the proper weight of genuine coinage, or grant advantage on an Intelligence (Investigation) check opposed by the buyer’s Charisma (Deception) check to realize that the currency is counterfeit.
