Eric mentioned that he hoped I wasn't taking on too much (regarding this vampire stuff we're chattering about), and it occurred to me that the reason it seems that way is because I'm not doing any of it. Here's to progress.
For my first question: How do I go about determining the agility of a microbe?
Seriously. I need a Bod BRA for a microscopic symbiont, and it's not Strength or Willpower. Strength I figure is 0@1 - not because the thing can actually lift 0.15625 oz, but because at that point we stop caring. Willpower is also 0@1, because while we can forgive a lack of sentience, force of will usually requires at least consciousness. For agility, I'm stumped.
On the one hand, the thing has no limbs. On the other, it could have plenty of cilia or flagella or whatever the fashionable motive structure is on Planet Zimbabwe, Galaxy Twelve. On the one foot, it doesn't do anything remotely like what agility measures in player characters, except perhaps swim through bodily fluids. On the other, it does plenty of other things that player characters don't - reflexive responses to entirely chemical environmental stimuli, manipulation of nucleic acids in host cells to indirectly maintain homeostasis - and if we don't use agility to govern that, what do we use?
Should I just base this call on the thing's physical agility and ignore other considerations? Even then, I'd like some advice on how agile a cilia-flailing single cell is in comparison to, say, your average twen-cen adult swimmer (inside of whom that same cell may be simultaneously flailing).

Second question has to do with Bod 13@ Actual Morphing skills.
The distinction in the rules between shapeshifting and morphing is that shapeshifting is superficial - we get the impression that it's mostly external, that the shape is changing but the metabolism is not - while morphing is fundamental, affecting everything from shape right on down to metabolism, blood chemistry, fire-breathing, the whole works. We're told that morphing grants the skilled character the physcial attributes of the form he's adopted - strength, stamina, agility, resistance, density, hand-eye, flexibility. Both skill types seem to assume a change in external form. The shapechanger says, "I want to be dog-shaped," and his skin and bones and muscles move around until he's dog-shaped. The morpher says, "I want to be a dog," and all eleven of his organ systems reconfigure until he not only looks like a dog, he has the sense of smell to prove it.
What about a morphing skill that effects no change in shape?
Obviously, if I have a bod skill that works through a symbiotic link and effects a permanent, fundamental change in the target (beyond simple healing or immunities), it's a 13@ Morphing skill. The question is, how do I determine a baseline? And, how do I balance the skill with others? (If the skill is exclusive to a non-player race, do I need to bother with balance? I'd say yes, but someone might disagree . . .)
Related question. Can I substitute a B13@ Morphing skill for a P0@1 Teaching skill for the purposes of skill acquisition? Could I do it with a B(4@/9@/14@) Symbiosis skill?
Assume I have a symbiont who morphs a host such that he both acquires new bod skills and gains permanent increases in several physical attributes. How many skills does the symbiont need, and how many rolls does it make, and how do I know?

I realize I'd thrown out a large number of vague questions, but I hope things will get more specific and/or more clear as we go on.
