Description: You use arcane lore to enhance your hearing to a supernatural degree.

Prerequisites: INT 13, 14th Level Arcane Caster

You designate one specific, proper name. Thereafter, if anyone within a radius of 10 miles per your arcane spellcaster level speaks that name, you hear it and instantaneously know the direction of, distance to, and name of the speaker. No concentration or action is required to gain this knowledge. Incoming information does not distract or hinder you, although the DM is free to adjudicate that if a great many people speak the name at once, the incoming information is lost, so wise mages choose uncommon names. Most choose their own name.

You may choose a new name as a standard action once per year, but only one name can be designated at a time.
