I would like to summarize my understanding about the whole broadly interpreted topic of Goetia. Please correct me if I don't understand something well!
A.) Ars Goetia is a non-Hermetic type of magic using 4 Supernatural Abilities: (Spirit)Summoning, Binding, Ablating, Commanding. It is purely Infernal, and registers as so for Sense Holiness/Unholiness, Hermetic Intellego magic or Faerie magic. (There are other, non-infernal Summoning methods, but those are not part of Ars Goetia)
B.) Goetic Magic is a border area of Hermetic magic and Ars Goetia: If a hermetic maga knows the particular Goetic Art she can "mimic" the infernal magic using her Hermetic methods: Rego and Vim. This kind of magic (AKA Goetic Magic) is not the equivalent of Ars Goetia, because it registers as Magic aligned for Magic/Hermetic or Faerie Intellego spells. For Divine or Infernal methods it registers as Infernal - just as the Ars Goetia.
With this kind of knowledge a hermetic maga can have a spirit as a familiar just as it would be a normal beast. So this is not equal of the mystery Spirit Familiar.
-It is not stated clearly that having a spirit as a familiar using this kind of method is just simply like Binding, or is it like the normal familiar cords? (AKA Cannot be dispelled without Ritual effect)
C.) (Spirit)Summoning: the semi-Hermetic method using Goetic Magic instead of pure Ars Goetia can copy all of the capabilities of Ars Goetia. Scouring is definetely an option which can't be imitated by pure Hermetic magic.
D.) Commanding: Knowledge about Ars Goetia - Commanding gives the options for Hermetic magi using Goetic Magic - Rego and Vim as Commanding-like power - to give such commands for spirits which are outside of the normal Hermetic capabilities to coerce spirits for services.
E. ) Binding: Binding is a special branch of power, because it is an magic power which could last indefinitely. Using Ars Goetia - Binding is an Infernal method, and a bound spirit can provide Supernatural powers of keep the target young "forever" without any Aging roll. BUT it gives 1 Infernal Warping / year.
Using Goetic Magic - Binding-like effect (Rego&Vim) is a Magic aligned power which can imitate the Ars Goetia Binding, but instead of Infernal it gives Magic Warping.
The power level of a Binding effect can be calculated based on the bound spirit: the effective lvl of a Binding effect is (Bound Spirit's Might + 1 Mgnt) . Based on that both Ars Goetia - Binding and Goetic Magic - Binding-like Rego&Vim effects can be 1. Sensed, 2. Supressed or 3. Dispelled as Infernal or Magic effects.
- Do I understand it well if a maga bound an Infernal Spirit (not a demon, just a spirit with infernal might) into her body using Goetic Magic (not Ars Goetia) than it register for Hermetic Intellego magic as a Magic aligned effect? And the spirit also cannot be detected bc of the "mending" power of Binding?
F.) Ablating: Knowledge about Ars Goetia - Ablating gives the opportunity for Hermetic magi using Goetic Magic - Rego and Vim as Ablating-like power - to have such options to consume spirits which are outside of the normal Hermetic capabilities to use spirits for serving or information.
G.) Receiving Warping Pionts id based on the alignment of the effect: Infernal warping for Ars Goetia, Magic warping for Goetic Magic.
- RAW says that Goetic Magic is always Magic aligned.
RAI suggests that Ablating (and maybe Binding and Commanding) is clearly Infernal stuff - no matters that the maga uses Ars Goetia or Goetic Magic, BC it forces spirits to suffer of extermintes them. Question is what is the situation when Hermetic magic uses Rego or Perdo effects to have the same results?
