Fortunately, you can swap between your unlocked classes at will, without incurring any further cost. You must unlock these classes separately for your main character and your Main Pawn in Dragon’s Dogma, and your hired Pawns cannot have their classes changed at all.
Can I play Dragon’s Dogma offline?
Yes, you can safely play Dragon’s Dogma offline. The only issue is that you will not be able to rent pawn from other players and you will not unlock achivements.
