If The Inexorable Search can pinpoint where a specific person is on a map, I see no reason why this spell can't also pinpoint where Gifted individuals are on a map of the same bounded area.
If the actual effect of the experiment is changed completely, but remains InVi, perhaps it identifies the existence and location of regios in the boundary area instead of Gifted individuals.
I think the difference is that The Inexorable Search has a target of Ind (ie. the one you're searching for). Because my target is Boundary, I need to add some levels of magnitude in order to pick individuals out of that boundary.
It's not changed completely, that's a different result on the table. The example given in the text is that inventing Curse of Circe with this result would turn people into goats instead of pigs.
That would be nice. I looked in HoH:TL and it's not in there, and that's the only Tremere book I have. Maybe it's in the Transylvania Covenant book?
Yeah, I tend to agree.
(c) I invented the spell, so that's already the case
(d) That would be cool
(e) I think that's less an issue if I add magnitude for details
(f) Hmm, possibly. It's a bit unclear (probably on purpose) of how much the effect is modified. They do give the one example I pointed out above.
It's definitely a ritual. Boundary target must be a ritual, and it was level 55 even before I add in magnitudes for detail.
It seems to me that what you need for "cerebro" is a combination of spells, one which lets you project your senses, and one which targets your senses to identify who has the gift: for example, using vision: sight of the gifted would be base:10, duration:diameter (+1) range:self, target: sight(+4) is InVi:35 then add scrying the distant location as base:1, +4 arcane connection, +1 diameter, boundry (+4) would be InIm:30. the problem is that with boundry it has to be a ritual which means it cannot be enchanted...
Well, if you stand by that interpretation, all you can expect from the spell is green light/red light to determine whether a person is Gifted in a given city, and then would have to rely upon other investigative techniques to find the Gifted individual. Meanwhile, you've just pinged every magus in the bounded area as the effect bounces off their Parma. And then, you only know if there is one Gifted person, not 2 or 10, or more.
The text for boundary is, "The spell affects everything within a well-defined [...] boundary." Intellego effects are about detection of a specific thing, that's how they affect something. Relaying that information via a map doesn't seem too over the top, certainly not for modified effects that are already present in your experimentation roll.
So the InVi 35 spell you described is the spell Spot the Gifted Child he invented (although I went with concentration vice diameter). My thought was that he casts the ritual, and gets an idea of where everyone with the Gift is located within a city (ie. in "that house", in the tavern, working in the field, etc). Then he goes there and then uses Spot the Gifted Child to identify the actual Gifted person.
The problem is range and target- you can project your senses to a place with an arcane connection, but locating someone (say on a map) requires an arcane connection to that individual, you can't have an arcane connection to "the gift" which is why you would need to project your senses instead. You could include modify senses under InIm in order to allow yourself more of a quick scan capability (echolocation with hearing and the gift detection tied to hearing?),
I'm not saying that the similarities are exact between Gifted Cerebro and Inexorable Search. They aren't.
But for the spell to be at all useful, besides a binary yes/no answer to the question, "Are there Gifted people here?" it has to have some cosmetic effect that transfers said information to the caster, all Intellego spells do this, to some extent. Inexorable Search shouldn't be able to tell you where something is on a map, but it does, if the person is in the area bounded (SWIDT?) by the map. Yes, an AC is involved, but the AC doesn't have knowledge of the map, the form of Corpus has nothing to do with maps, yet it works...
It could be that Gifted Cerebro only provides range and bearing to the target, range is indicated as a pull that is harder or softer depending upon distance from the caster. Solomon would then have to document, on a map or journal, where all of these targets are based on an estimation of range. Also, it's an expensive spell, requiring a lot of vis to cast. Solomon could have just easily made it T:Structure, and then proceeded to go through a city/town/village at night being all creepy to see if a Gifted child lay within.
The thing is that Intelligo Corpus has an listed effect at level 3 of "find a person with an arcane connection" so 'locate with an arcane connection' isn't a general range or target for intelligo spells (perhaps it should be, but that is a different topic). A minor breakthrough might be able to discover that effect for InVi, or a way to make it more general for In spells...
Locating a person doesn't have to be with a map though, it can be range and bearing. IMO, Inexorable Search opens up the idea that you can link things to a map, whether their is an AC or not. The AC is irrelevant, except for the guideline you indicate. My Mercere Corpus specialist in another saga uses that InCo guideline all the time to get range and bearing to people he has an AC to, because, let's face it, medieval maps suck.
I don't suppose Winter 1239 or Winter 1241 would work? Those are seasons he's working for the covenant and his time isn't claimed.
No, the difference is between "detect" and "locate"
InVi base 10 detects the gift
Inco base 3 locates a person
Then, as I've said, the design of such a spell only tells you if there is at least one Gifted individual within the bounded area. Period. It's not terribly useful, then.
The multi spell way would be to:
an effect to move your point of perception to high above the location,
An effect to draw what is seen like the mapping spell.
Then the detect gifted spell at range vision which we have.
Those there effects could be made into an item giving you a Cerebro unit. And the unit produces a map/picture of their location.
I like it in one spell which is used by the caster and that will still probably be quicker in terms of seasons. It may over time be cheaper for vis.
I've wanted to create a mapping "drone" like this for years.l with a character because normal maps are poor.
ReHe to spread the ink on the surface as a reflection of what you see. It could require a bit of finesse though...
Re: Cerebro,
It's tricky because the Forms certainly do not line up the same guideline power levels for similar effects (on of the charming things in Ars I actually like).
Both verbs in those sentences could be seen to be sub-sets of each other depending on how you interpret them.
My 2c: I think the spell as designed should be generous about how it functions (as JL said). However finding a specific person amongst a set of "pings" is harder than the base guideline though, but not very hard as the spell design is a nice match to the purpose - I'd add +1 mag.
That, plus Inexorable Search requires an Arcane Connection to the target, so it's not like "I know Delenn of Jerbiton is somewhere in Shropshire, so if I have a map I can find her." You would need an AC to her to find her on the map. With this spell, as I understand it, it just tells you whether there are any Gifted individuals within the boundary that you walked while casting the spell, with a rough idea of how many.
Re: Solomon's Cerebro effect.
Found it: InCo 2 - Count the number of individuals in the spell Target (TMRE p.93).
Question: well, actually, preface and then question. But still.
Preface: The Spell Mastery tomes on the wiki don't have what the mastery is for the spells they cover.
Question: By studying (for example) On the Invisible Sling of Vilano, does it provide that Source Quality in points that can be applied to any Spell Mastery (or multiple Masteries), or should it only provide those points to a specific Mastery?
You can learn any spell mastery.
