I am a little confused in one area-- some powers (take Augment Summoning for example) have free action casting costs, but then state Verbal Casting.  Do these require an action for the Verbal Casting or not?  I was thinking it meant as a free action you could add the component-- but then I saw Bit of Luck which is a reaction with a somatic casting component.  So for Bit of Luck would you need to spend your reaction + an action somehow, or is the component for free in these cases?
