AGAIN with the allied spirits!, Plotting, plotting Options

[Tiralee]

Well, after re-reading MiTs, I decided to have a bash at creating an ally for my pimped-up pryofiend (Based loosely on WitchHunter Robin)

Now, at force 4 with a few extras (Uh, yeah. No sex-toy forms. Or knives.) I closed it out to a doable 79 Karma. By the example in the book it'd round down to a TN of 15.
(Am I right so far?)

Now, can I use any additional dice apart from my Conjuring 6 (Karma, spellpool?) for the Formula Creation Test?
If yes, I can use Spellpool, that puppy is going to have a TN of close to 20 with the added extras, leather interior and hatchback option!

Sadly, she is one of the most level-headed characters I've ever played. The ever-present threat of bodily-harm will do that.

Help, laughter, flames?

Thanks,
