Choose a class you have levels in.  You have learned to cast spells of that class more effectively.

Prerequisite: You have more hit dice than you have levels in the chosen class.  The chosen class may not be a favoured class.

Benefit: Your caster level in the chosen class increases by two, but this feat may not increase your caster level beyond your total number of hit dice.

Special: You may select this feat more than once.  Its effects do not stack.  Each time you select this feat it applies to a different class.  If you have multiple abilities that increase caster level, apply those that are limited by hit dice first.
