Er, no. Lawful barbarians and bards are not within the class rules on which this game is based.
Barbarians and bards are chaotic by nature.
- "Barbarians are never lawful. They may be honorable, but at heart they are wild."
- "Bards are wanderers, guided by whim and intuition rather than by tradition and law."
Monks and paladins, on the other hand, are lawful by nature.
- "A monks' training requires strict discipline. Only those who are lawful at heart are capable of undertaking it."
- "Paladins must be lawful good, and they lose their divine powers if they deviate from that alignment."
The alignments oppose each other, as they are meant to.
