@littha: what does it do? I don't have the book, can you write something that I can put in?
@snakeman: well, the feat says "When you select this feat, choose a draconic aura (see page 86). .... " Vigor is in a different book, so that's why I think it's a bit dubious at least (also, one of the other handbooks on healing states it isn't RAW). Of course , you could say that the "see page 86" refers to information about draconic aura's and not to the aura's that you can choose... I'm not certain what's meant in any case.
