Eclectic Training

You took to heart that any true master knows life often requires people to train in different subjects.

Prerequisite(s): Ability to cast 1st-level spells.

Benefit(s): Choose one spellcasting class you have at least 1 level in—you increase your effective caster level in that class (including the number of spells you know and can cast per day) by +1, to a maximum caster level equal to your total Hit Dice. Single-classed spellcasters should still pick a class to which this bonus applies, since this bonus is retroactive.
