Does anyone know if there is a 3rd party Mesmerist class archetype out there that trades some class abilities for access to spells that only the Psychic class gets (aka ego whip, id insinuation, intellect fortress, mental barrier, mind thrust, psychic crush, thought shield, tower of iron will, etc etc)??
I don't, but you could get those spells as a Samasaran. It's not as good as what you're looking for at all though.
So, as far as anyone knows, there's no 3rd party archetype like this for the Mesmerist?
