The personal reading spell allows the priest to mathematically analyze personal information about one human or demihuman character and learn valuable facts about that character. To cast this spell, the priest must know the subject's real name (the name the subject was given as a child) or the date and place of the character's birth. The priest analyzes this information and is able to build a rough picture of the character's life history and personal specifics.
The "historical" information discovered through this spell is generally vague. For example, the priest might learn that the subject was born in the woods and moved to the city only after hardship made his life untenable. If the priest casts the spell based on an alias or incorrect birth information, the reading will be inaccurate. The subject need not be present during the casting. The priest can cast the spell without ever having met the subject.
Note: This spell originally appeared in this form in the Tome of Magic for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
