The compassion to pursue good, the will to uphold law, and the power to defeat evil -- these are the three weapons of the paladin. Few have the purity and devotion that it takes to walk the paladin's path, but those few are rewarded with the power to protect, heal, and smite. In a land of scheming nobles, unholy priests, inscrutable dragons, backstabbing guilds, and infernal fiends, the paladin is the final hope that cannot be extinguished.
The paladin's chief role in most groups is as melee combatant, and her spell selection is helpful in battling evil.
