"Enh, magic spiders don't natively have venom as potent as a black widow, let alone the leap of, I can't remember a jumping spider off the top of my head, and they can't do kiting. Plus the eye stuff! Personally I think the eye stuff is neat. But just because I think it's neat doesn't mean it floats your boat."

"The eye stuff is interesting... how expensive would it be to collect all the ranks, though, on top of my excessive amount of heritage?"

"Either nine points or six, depending on if Spider was your primary race or not."

"What other effects does primary race have?"

"It can tiebreak in cases where one race's physical attributes would be more or less dominant over another's, and it determines your affinities. You only have the affinities of your primary race and not your other races. Also, if you have biological children, it can effect what admixtures they grow up with--in general, a chimera counts for hereditary purposes as about half your primary race and a quarter each of the others, arranged in such a way that you get approximately a full dose of each one, but if you have children with someone who's a fourth thing, one eighth has less influence compared to a quarter than a quarter does compared to a half."

In that case... consider the implications of your choices, Liam.

"What are the affinities of Gnome, Pixie, and Spider, and what implications do those affinities have?"

She highlights the two "flavors" attached to each star--beast and metal for Spider, metal and nature for Gnome, and nature and wind for Pixie. 

She also highlights how many of the further out stars have one "flavor" affinity each. 

"An affinity you have makes buying powers related to that affinity cheaper; about half price, rounded down."

"Perhaps I'll decide for now to be Gnome first and Pixie and Spider second, and see if anything related to beast or wind catches my eye later on."

"Sure." 

He can sort of feel how to tug on the different stars to bring the three race ones sort of tentatively clicked into place, with two iterations of "Hybridize" gluing them together, Gnome directly adjacent to him and Pixie and Spider attached to it. 

He arranges this. Pulling all the stars around and setting them into place is sort of soothing. Like playing cat's-cradle.

"What's next, then?"

"Traditionally the next step is dealing with complications, but there isn't a strict ordering."

"I can't think of a particular reason to turn somewhere else first. Let's see about complications."

"Complications," she highlights a ring of stars that connect to class but have no racial affinity, "are a class of magical traits which give points instead of costing them, which tend to be neutral to negative, although there are of course niche ways to turn anything positive."

Time to investigate them all methodically in detail? Time to investigate them all methodically in detail.

Complications he has access to include: 

(2 points) How do you feel about a random supernumerary nipple.

(4 points) Do you not give a crap about nature? Well, nature doesn't give a crap about you, unless you take this complication, in which case nature actively dislikes you!

(12 points) Do you want to not do magic after all? Have a crippling magical disability! This one makes you not able to take any ranks of magic above zero, or any perks that cost more than four points (except racial perks)

(2 points) Being extra attention-getting! Might be useful if you're tiny

(3 points) Do you want to be a permanent child? 
-(+1 point) And have nobody take you seriously?

(4 points) The veil doesn't cover you, if you go out in all your tiny winged spidery glory you're going to cause an automatic masquerade breach unless you, like, build a human-passing mecha to pilot around or something. 

Certainly a... varied selection. (He instinctively wishes there was some kind of trash pile into which he could put the 'suck at magic forever' star, just to make extra sure he never accidentally touches it.)

"Dare I ask how the, er, nipple option, would come across if I were a Hollow or a Spider?" he says, mostly out of morbid curiosity.

“A Hollow would end up with a nipple-shaped crinkle in the metal somewhere. A spider would wind up with a fleshy nipple growth somewhere on the outside of their exoskeleton.”

"Neither of those sounds especially appealing but I suppose a lot of things can be worthwhile as a trade for power. What else is there for Complications, or is that all?"

"--Oh, as a gnome hybrid you'd probably end up with a basically normal witch mark on ordinary skin."

Additional complications include: 

(4 points) One of your senses is dulled. Can be taken up to three times. 

(2 points) One of your senses is enhanced, to the point of over-sensitivity. Can be taken up to three times.

(2 points) You are permanently addicted to some substance or stimulus. Can be taken up to three times. 

(4 points) You are permanently missing a limb (healing and shapeshifting can't put it back; prosthetics do work). Can be taken up to four times.

"...is there anything preventing me from deleting four of my eight legs and then replacing them with prosthetics?"

"There is not!"

(8 points) At some point, an enemy will have you at their mercy for some unspecified amount of time before killing you.

(power variable) You have a personal kryptonite. 

(2 points) Your magical power is directly tied to your physical fitness; if you don't exercise, your magical effectiveness will dwindle to about half
(+2 points) will dwindle to nothing

"...part of me wants to know more about this hypothetical enemy and part of me would rather skip it. What else is there?"

"The hypothetical enemy isn't pre-determined, or anything; most people don't have any enemies when they first awaken, unless their family has a blood feud with someone or something."

(1-8 points) You feel an internal compulsion to do something under some circumstances. 

(6 points) You require an external implement in order to do magic.

"...is the compulsion something I can specify - is the enemy something I can specify—?"

The compulsion is absolutely something you can specify. The enemy is not something you can specify; it doesn't mind-control someone into falling in enmity with you, it just guarantees that you will, at some point, cross paths with someone who will do so without any mind control.
