Magic Number

Certain Numbers have magical properties or symbolism associated with them.

0

A hollow circle or space, the Darkness Rune.<ref name=":0">Bonus Material: Binding and Countermeasures</ref>

1

Something of special importance - a single, central symbol with extra effect.<ref name=":0" />

2

Usable in certain Diagrams involving duality or pairs, such as a Host or other Vessel.<ref name=":0" />

3

Main article: Rule of Three

The first of the really significant magic numbers.^{[citation needed]}

5

The number of the "Heirophant" Tarot Card, which represents an institution, often related to Incarnations.<ref name=":0" />

12

Like 3, repeating something 12 times can help it come true, with some Practice.<ref name=":1">“You keep telling yourself that,” Kass said.  “At least twelve times,

maybe seventy-seven times.  Maybe you should try gunning for one of the
higher magic numbers, like one hundred and forty-four, put a little 

practice into it, and see if it comes true.” - excerpt from Cutting Class 6.1</ref> (Perhaps because it's 3x4, so it's the rule of 3 four times over.)

13

Symbolises misfortune. The number of the "Death" Tarot Card, which represents transformation and rebirth, possibly but not necessarily literal death.<ref name=":0" />

15

The number of the Tarot Card "The Devil", which represents the "shadow self" and being bound. Also 3x5 so it can draw on the implications of those numbers combined.<ref name=":0" />

77

Like 3, repeating something 77 times can help it come true, with some Practice.<ref name=":1" />

99

3x33; the Rule of Three 33 times over. A pattern repeated 99 times is very hard to break, as with Rackspatter's 99 scalps from Practitioners who tried to bind him.<ref>“I don’t suppose you know where there are any superior goblins?” she asked.

“I’d be betraying my guests if I directed a practitioner their way.”

“Goes against the whole point, huh?”

“Yes.  In theory, I could point you to a certain individual who betrayed my rules, Rackspatter of the Nine Thousand Scalps, but I wouldn’t be doing you a service.  For one thing, he can’t be bound.  If I remember right, ninety-nine of his nine thousand scalps are from practitioners that tried and failed.  It’s like the rule of three, reinforced thirty three times over.  At this point, it’s a foregone conclusion.  You’d be the hundredth.”

“And he’d be over nine thousand,” she said. - excerpt from Signature 8.7</ref>

144

Like 3, repeating something 144 times can help it come true, with some Practice. One of the higher magic numbers.<ref name=":1" /> (Perhaps because it's 3x4x12, so it's the rule of 3 fourty-eight times over, or a twelvefold repetition twelve times over.)
