Cannibal
Eat parts of people. Depending on what you devour, you may acquire a skill that belongs to that person's job, refill HP, or choke on an item and then get to keep it.
Stalker
Run around stalking everyone. You have enormous physical strength and you specialize in instant death attacks, however you're very slow, and you usually miss. Once you get an invisibility cloak off of Mount Germinas though, you're a killing machine.
Bar Tender
Like a Chemist, but with booze.
