I've decided to retrain my level 18 seeker quite a lot to give her a better chance in the DPR Olympics, but I can't wrap my head around one question.
I took Snake Fang as a normal feat at level 3, and now I also have both Snake Sidewind and Snake Fang. I want to dip into Style Shifter at level 18. That archetype gives a style feat at the first level. My goal is to get Snake Style from the archetype and get a new feat instead of the one I took at level 3. I am not sure how to do it correctly.
Is it possible to take Snake Style as the feat from Style Shifter, and then instantly retrain the feat I took at level 3 into something more useful, all just for 5PP? AFAIK, having two of the same feat is not explicitly prohibited anywhere, they just don't stack unless the description says otherwise.
Or do I have to jump through hoops, get a style feat I don't need, and then do a whole lot of retraining? If so, how much PP would such a retraining cost?
I know that my retraining has got to be signed by a GM, but both of us don't really know how to do it best.
