Classify

You choose one creature, alive or dead, that you can see. You learn what the creature is called, its creature type, and some well known information about the creature such as its native plane. It does not reveal the name of a specific creature, nor does it reveal any gameplay features that creature has. For example if you cast it on an imp, you would learn it is an imp, it is a fiend, and that they are commonly found on the lower planes and usually serve a master, but you would not learn any resistances or immunities, or other abilities the imp possess.
