Being a paladin is its own reward. Fight honorably, let others know your righteous stance, and do not be afraid to call out evil. The power of law and good is with you. Dispense justice with mercy, destroy any evil you detect, and be unfaltering in the face of fear.
Always pay top dollar for your inn room, tip heavily, spend uncountable hours grooming your horse and taking care of your gear, and only accept adventures with clear goals and superior motives.
Refuse to accept any evil people in your group, always announce yourself to the authorities in every town and city, never hide from a potential fight, and preach constantly to your group members the virtues of your calling and your god.
Be the paladin.
