Tingling Ear

The caster writes a name by which they are known on a piece of paper. The name can be a true name or a moniker, or the caster having been misrepresented to the speaker, but cannot be an unspecific description such as, "the elf with the two crows" or "she whose name shall not be spoken".

With this paper carried somewhere on your person, you perform the verbal and somatic components, and for the following 8 hours "your ears tingle" any time that name is spoken in reference to you. You faintly hear the name spoken by the speaker's actual voice. A speaker who does not wish to be located must make a wisdom save against the caster's DC. If they fail or choose to fail, the caster knows the distance and direction of the speaker, or if the speaker is on another plane, which plane. 

Someone speaking the same name in reference to someone else is not affected. The caster cannot use a name by which the speaker does not mean to refer to them, for example, to sense uses of a name intended to mean someone else.
