PREREQUISITES
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 higher-than-average ability scores.
