So one of my players created a 1st lvl Sorceress with Aberrant bloodline. According to the rulebook, she gets the Improved Grapple bonus feat. Yet the description for that feet requires Dex 13, she has 11 though. Does she still get to have the feat because it is a Bloodline ability?
She does not get that feat for free.
She can take that feat for one of her bonus feats if she meets the prerequisites for the feat as per the class text.
That is... not how bonus feats work. You get to pick a bonus feat from the list at level 7, and every 6 levels afterwards. It is specifically stated that you need to meet the prerequisites for those feats. There is nothing at 1st level, and no absolutely set feats.
Bloodline: Each sorcerer has a source of magic somewhere in her heritage that grants her spells, bonus feats, an additional class skill, and other special abilities. This source can represent a blood relation or an extreme event involving a creature somewhere in the family's past. For example, a sorcerer might have a dragon as a distant relative or her grandfather might have signed a terrible contract with a devil. Regardless of the source, this influence manifests in a number of ways as the sorcerer gains levels. A sorcerer must pick one bloodline upon taking her first level of sorcerer. Once made, this choice cannot be changed.
At 3rd level, and every two levels thereafter, a sorcerer learns an additional spell, derived from her bloodline. These spells are in addition to the number of spells given on Table: Sorcerer Spells Known. These spells cannot be exchanged for different spells at higher levels.
At 7th level, and every six levels thereafter, a sorcerer receives one bonus feat, chosen from a list specific to each bloodline. The sorcerer must meet the prerequisites for these bonus feats.
You don't get all those feats for free. You get 1, and you have to meet the prerequisites.
Dang, not sure how I missed that but makes much more sense. I thought that seemed ridiculous for a 1st level character. Thanks all!
