Choosing Inspiration Specializations 

As they increase in Rank, player characters may decide to specialize in up to three specific uses of Inspiration. This Specialization does not prohibit other uses of Inspiration and each Specialization may only be applied once during each opportunity in which Inspiration can be used. Most Specializations double the effect of one Inspiration the Player spends for that purpose.

A player may choose one Specialization upon achieving Ranks: 2, 4, and 6 or any time afterward. This is a total of 3 potential Specializations.
