Well I stand corrected, as a designer stepped in. Although I do have to say it feels like a cop out.
Since we've established that Characters can take "feats that don't work for them" do those feats still function as prerequisites?
For example, a human / kobold could take Draconic Aspect, even though he doesn't have scales, so the feat would be useless.
Could he still use Draconic Aspect to fulfill the requirements for Draconic Glide or would he be disqualified because even though he has the pre-req, he can't use it? Unlike Tail Terror, Draconic Glide clearly states "you grow a pair of wings."
Also, is it just me or does it seem like there are lots of relatively easy ways to gain permanent wings, but very limited ways to gain a tail?
that is a very good question you should faq that question. that is an actual legitimate question.
