To qualify for a new class, you must meet the ability score prerequisites for both your current class and your new one, as shown in the Multiclassing Prerequisites table. For example, a barbarian who decides to multiclass into the druid class must have both Strength and Wisdom scores of 13 or higher. Without the full training that a beginning character receives, you must be a quick study in your new class, having a natural aptitude that is reflected by higherthan-average ability scores.
