THE MULTICLASS CHARACTER
As your character acquires experience and advances in Level(or if your character starts above1st Level), he or she may choose to gain Levels in one or more new classes instead of only advancing in a single class.Adding secondary or tertiary classes gives the character differentadvantages, but progression in the new classes occur at the expense of advancement in the character’s other classes.
For example, if your character is the lone Magical Girl in her adventuring group, she may decide to advance in that class only. If a new Magical Girl also joins the team, the two characters may decide to gain several Levels in the Sentai Member class to compliment each other’s abilities before progressing in the Magical Girl classonce again. While your character continues gaining Sentai Member Levels, her current Magical Girl Level remains the same and does notincrease. When she decides to start advancing in the Magical Girl classagain, the Sentai Member Level remains constant. Your character canonly advance a single Level in one class at a time.
For more information on the multiclass character, see
the Player’s Handbook. Though BESM d20characters do notusually suffer Experience Point (XP) penalties formulticlassing, the Game Master may decide otherwise.
