I'm gonna give it to you straight, I am not the world's biggest fan of the archetype; while I realize there's precedent now for altering BAB and the like, I don't really like how this hard-locks the 'fex into a particular archetype. The loss of essentially three skills (since you now non-optionally require Intimidate) hurts in the out-of-combat utility in a bad way, and the custom malefaction raises awkward questions of interactions with the existing malefaction rules and, more impotantly, with immunities and targeting.
Thanks for your honesty Prince of Knives! The archetype was put together on a whim in a very short time span. I simply thought it would make for an interesting concept. Not fully realized but more conceptual in practice. As far as "locking" a class into a more focused route I would have to disagree with you on that regard as many archetypes already do that. They offer up something, which can be extremely focused, by giving up or sacrificing another aspect of the class. Some archetypes completely change the forte or focus of it's parent.
You may end up enjoying the upcoming Rustpicker archetype, though.
This sounds very interesting!
