I think that the "Kiss of Mephistopheles" Hexing Blade option should be renamed to "Blasting Hex", the reason being that to have the option be named after "Mephistopheles" is to kind of bind it to the Fiendish Sorcery Origin, rather than keeping it Origin neutral, as I think it should be, but that is just my take. Also, you goofed up on Page 14 of your draft, I can't see half the page. You also goofed up the format of the Celestial Sorcerous Origin on Page 141. I will also see what I can find in the way of alternate names for either the Sorcerer class or its full-caster archetype.
