Blackfire Pact (Su)

At 3rd level, a Blackfire Adept may choose one evil outsider subtype from among the following: asura, daemon, demodand, demon, devil, div, kyton, oni, qlippoth, or rakshasa. Against outsiders with that subtype, she gains a +1 profane bonus on saving throws, caster level checks, Charisma checks, and Charisma-based skill checks. When using the planar ally or planar binding spells, she can call 2 additional Hit Dice of outsiders with the chosen subtype, and those creatures gain temporary hit points equal to her class level, a +1 profane bonus on saving throws, and a +1 profane bonus to the caster level DC for effects that would banish, dismiss, or dispel them.

At 6th level and 9th level, the Blackfire Adept may select an additional evil outsider subtype for her blackfire pact. In addition, the bonus against any one of her selected subtypes (including the one just selected, if so desired) increases by +1.
