Becoming a paladin involves taking vows that commit the paladin to the cause of righteousness, an active path of fighting wickedness. The final oath, taken when he or she reaches 3rd level, is the culmination of all the paladin's training. Some characters with this class don't consider themselves true paladins until they have reached 3rd level and made this oath. For others, the actual swearing of the oath is a formality, an official stamp on what has always been true in the paladin's heart.
