Player's Option: Spells & Magic[]
Law: A character with this proficiency is thoroughly familiar with the legal system of his homeland and is skilled in representing cases before judges, officers, nobles, and magistrates. This is a working knowledge of the law, as opposed to the theoretical knowledge of the sage area of study. With a successful proficiency check, the character can build a strong defense for a person accused of a crime; if the judge or jury are fair-minded and honest, he stands an excellent chance of winning his client's case. Of course, corrupt or intimidated officials can still deliver unjust verdicts despite the character's best efforts.
The Complete Paladin's Handbook[]
A character with this proficiency is thoroughly familiar with the legal system of his homeland (or any other region of his choice). He knows which laws are rigorously enforced (illegal gambling may be tolerated in one region, aggressively prosecuted in another), and routine legal procedures (such as how to file suit against a debtor). Understanding nuances of the law, such as interpreting fine points of a contract, require proficiency checks.
A successful proficiency check also allows the character to conduct a strong defense when he or a companion stands accused of a crime. If the judge is fair-minded and the evidence of the crime is ambiguous, a successful check will sway the verdict in the defendant's favor; either he receives the smallest possible sentence or fine, or is completely vindicated. However, if the evidence clearly calls for a conviction or the judge is corrupt, a successful proficiency check won't help.
A character may spend additional slots to know the legal systems of other regions. Alternately, he may spend slots to acquire expertise in a particular area of the law, such as tax codes or property rights. Expertise assumes a broad understanding of the chosen area, requiring checks only in extreme instances.
Crossover Groups: Warrior, Priest.
Law and Paladins[]
A paladin with the Law proficiency won't defend anyone he believes to be guilty, including his own companions. Though a paladin won't knowingly break the law, he may take advantage of this proficiency to defend himself if wrongly accused of a crime; a failed defense may result in his conviction.
Warriors & Priests of the Realms[]

The law proficiency familiarizes a character with the laws of his city or country. He knows what is legal, how severe each crime is, and what the punishment is. This is identical to the law proficiency as included in the Complete Paladin's Handbook.
