Kk, that's straightforward enough^^ (oh, and to answer question 2, since I missed it before, it uses your symbiote's HD). What class are you? I'm assuming archivist from the "Divine" tag rather than a class list? If so, how lenient is your DM about adding stuff to your spell list? A lot of the spells that work best are off the Sorc/Wiz list, and with work you can get them, but I don't want to waste time if he's going to shoot down any additions.
