I've already read all the posts that specifically deal with this and I still have some unanswered questions. I have pasted all related Paizo material that I can come up with, at the end of this post. And now to my dilemma. I have a Wildblooded Tiefling Sorcerer who is Pit-Touched. So, I'm a Tiefing and I have Fiendish Sorcery... the two prereqs for taking Improved Fiendish Sorcery. But it seems as though they added a prereq under the benefits which is really confusing. I think maybe the intention was to add a bonus to Rakshasa and Shadow bloodlines but I would love to be able to take this feat for my own character, and according to the prereqs, I qualify. It just grates against every logical tendency in my brain that they would ADD a prereq in the BENEFITS. Any thoughts would be welcome.
Here is the Blood of Fiends feat, verbatim:
Improved Fiendish Sorcery
Your skill with foul sorcery is even more potent than that
of others of your race.
Prerequisites: Fiendish sorcery racial trait, tiefling.
Benefit: If you are a sorcerer and possess the Rakshasa
bloodline (Pathfinder RPG Ultimate Magic 68) or Shadow
bloodline (Pathfinder RPG Advanced Player’s Guide 140), treat
your Charisma score as 2 points higher for all sorcerer
class abilities.
Here is the Fiendish Sorcery racial feature, verbatim from Advanced Race Guide:
Fiendish Sorcery: Tiefling sorcerers with the Abyssal or Infernal bloodlines treat their Charisma score as 2 points higher for all sorcerer class abilities.
From Ultimate Magic:
Wildblooded
A wildblooded sorcerer has a mutated version of a more common bloodline, with one arcana and at least one bloodline power that are different from those of an unmutated bloodline. When creating a wildblooded sorcerer, select an existing bloodline, then select one of the following mutated bloodlines associated with that bloodline. Use the normal bloodline's class skill, bonus spells, and bonus feats, and the mutated bloodline's bloodline arcana. Use the normal bloodline's bloodline powers, except when the mutated bloodline replaces one of those powers.
Pit-Touched
Your diabolic corruption is from a source in the deepest parts of Hell.
Associated Bloodline: Infernal.
Bloodline Arcana: Whenever you cast a spell, you gain a bonus on Intimidate checks equal to the spell's level for 1 round.
Bloodline Powers: The crushing weight of evil has given you the strength to endure.
Tough as Hell (Ex): At 9th level, you gain a +2 inherent bonus to your Constitution. This bonus increases to +4 at 13th level, and to +6 at 17th level. This bloodline power replaces hellfire.
