How does Practiced Spellcaster interact with the wild magic class feature of the wild mage (from Complete Arcane)?
The –3 penalty and +1d6 bonus to the wild mage’s caster level are applied as a single step in the process of determining the wild mage’s caster level. Since Practiced Spellcaster’s bonus is always applied when it is most beneficial to the character (see previous answer), a wild mage with Practiced Spellcaster would typically apply the wild magic class feature first (subtracting 3 and adding 1d6 to her caster level) and then add the Practiced Spellcaster benefit, up to a maximum value equal to her character level. For example, if a 5th-level wizard/4th-level wild mage with Practiced Spellcaster rolled a 1 on the 1d6 bonus to her caster level, her caster level for that spell would be 9th (base 9th, –3 from wild magic penalty, +1 from wild magic bonus, +4 from Practiced Spellcaster up to a maximum equal to her character level). If she rolled a 6, her caster level would be 12th (base 9th, –3 from wild magic penalty, +6 from wild magic bonus; the Practiced Spellcaster bonus would not apply
