Re: Skill Points
Strands of Fate (for comparison purposes only) has a "Summon Creature" power. Buying it costs a number of points equal to 2 + the summoned creatures highest Ability (Ability = Skill in DFRPG). Nothing specifying how many Abilities happen to be high, nor are Powers even addressed.
Rather than charge per skill point, though, perhaps we make the ritual complexity = n! where n = the highest Skill rank.
So, a creature for which Superb is the highest skill rank would add a Complexity of 5+4+3+2+1 =15
Edit: As an option, to keep people from gaming this system, we could charge +1 Complexity for each additional skill the creature has at that maximum rank. So a creature with a max of 3 Superb Skills would cost 17 (15 for having one Superb skill, and +2 for having 2 more) while a creature with only 1 Superb skill would still cost 15.
Edit #2: the rules for conjuration say that 2 shifts are required to give something animation, which I imagine is like installing a very simple AI to operate the conjured object. Perhaps Conjuration and Golem Crafting can be aligned in some way? Maybe a basic golem AI is 2 shifts, which would be enough to get it to "act" like it was a real... whatever it is. And after that, we tack on complexity for any powers and skills it would have.
Specifically, I think Skills should be a factor of the AI piloting the golem, while Powers should be a factor of the mystical body prepared for it, a series of enchantments that the piloting AI could control, much like a guy in a fighter jet. Just make sure that if your Golem has a Breath Weapon, the AI has ranks in the correct skill to use it.
Edit #3: We may want to split the Skills/Stunts between the AI and the Body:
Body: Might, Endurance and any stunts related to these two skills
AI: Alertness, Investigation, Fists, Guns, Weapons, as well as Stealth, Discipline, Deceit, Burglary, and any other skill or stunt, really, unless they are clearly a function of the body
