@Harakani - Go for the Occult Scientist. I am submitting an Occultist (it's this avatar), but the narrative abilities didn't really fit the class. I'm just planning to go with the two traits unless our GM decides that we must have a narrative in which case, I'll go with a different one that hasn't been picked.
@Eltacolibre - As stated above, the Occult Scientist abilities don't really match up with the Occultist class (which is not surprising as they weren't made with each other in mind), so I am going with the two traits unless you specify otherwise. Heirloom weapon matched up well with the class in granting proficiency with a specific falcata; an ancient heirloom held in the character's family for generations. Master of Pentacles also seemed appropriate as I am leaning towards the Conjuration and Transmutation Implements (the final book will be the deciding factor as Conjuration was unplayable in the playtest due to no summoning spells). A family history of working with summoning circles and calling extraplanar creatures.
It's still a work in progress and not quite finished (spells, implement powers should be all that's left, but I cannot access the playtest anymore so I have to refer to my print out when I'm at home).
