Multiclassing works more or less as usual to 3.5 multiclassing, with the following exceptions:
- Class skills: No matter which class you're actively leveling, all class skills from each class are considered class skills where leveling them is concerned.
- EXP: There is no detriment to EXP for multiclassing into more than two-three classes, provided you are realistic with it and don't foce me to change my mind. B|
