Advanced Spellcaster [GENERAL]
Through difficult training and extensive practice, you have advanced your spellcasting prowess even while pursuing other paths.
Prerequisite: Caster level 9th, Practiced Spellcaster, 5 levels in any class other than the one this feat applies to [This class has to be irrelevant/ineffectual in respect to the spellcasting advancement (Spells per Day) this feat applies to].
Benefit: Your caster level for the chosen spellcasting class increases by 1 (including Spells per Day). Treat your Spells per Day and caster level as if you gained a level in the chosen spellcasting class. This benefit can't increase your caster level to higher than your Hit Dice. However, even if you can't benefit from the full bonus immediately, if you later gain Hit Dice in levels of nonspellcasting classes, you might be able to apply the rest of the bonus.
Special: You may select this feat multiple times. Its effects stack. You cannot take this feat in the same level that you also receive new Spells per Day from a class.
