Duplicate

You hold and examine a simple inanimate object of Small size or smaller for the duration of the casting and then touch the material components to create a duplicate of the original. The material components are required and consumed by the casting. All aspects of the copy are identical to the original in form and function, however no magical properties of the original are duplicated. The original object must be simple in nature (e.g. a statue, tablet, weapon, key, or a tool) but can contain carvings, writings, etc. Complex objects (e.g. mechanical clock, corpse, manuscript with multiple pages) cannot be duplicated by this spell.

Upon close inspection, a creature familiar with the original can determine that the duplicate is copy with a successful Investigation (Intelligence) check against the caster's spell save DC. On success, the creature notices subtle differences that identify it as a copy. On failure, no further inspection by the creature will reveal the object as a duplicate. If the raw materials used are not identical to the original (e.g. using simple bone instead of ivory, a different type of animal leather), the creature has advantage on this check.
