Just that question: I was going through potential story seeds, and was thinking about labwork and what a character could actually reasonably learn from going to the nearest village and kidnapping/bribing/mentally dominating the local heggie for a season or three. And honestly I'm having trouble with a few of them. Of course, it may be that the underlying game mechanic/magic is simply already incorporated into the Hermetic Arts as of 1220. Some seem to not yet be fully Integrated, though:
Animal Ken - Intelligo Animal. That's...pretty much it, which has been fully integrated. Although the Animal can understand you as well, so there's some implied Creo Mentem?
Dousing - likely one of the original sources of general Intelligo magic, as well as Sympathetic bonuses. However, Dousing is not restricted by Hermetic Range or Size - rather, it's roughly measured in Paces, rather than strict boundaries. I'm...not quite sure about this one. Maybe have a "paces" Size, (1 pace = 0, up to 1 league = +3)?
Enchanting Music - well, it's pretty much emotional control, which has already been integrated into ReMe. However, it's action is the very definition of Performance Magic. So, I'd call Performance Magic (Singing and/or Musical Instrument) to be a partially-integrated version of this Ability. Also could be considered a source of Sensory (Sound) magic.
Entrancement - Straight-up Mind control. Also covered by ReMe. However, it's activation technique is just eye contact. This is likely one of the sources of Range:Eye (along with other various "evil eye" traditions), and has been fully Integrated. Arguably, the Ability also includes Deft Mentem, as the ONLY thing you do is stare into the target's eyes. Or to make it more interesting, the additional Insight is "Deft Eye: any Eye-range spell does not require Gestures or Incantations". Hm.
Premonitions - ooh. A toughie. This seems to break the Limitation of Time, although it doesn't give specific information. The safe bet is that it's probably a source for Hermetic Divination. Beyond that... I'm not sure.
Magical Sensitivity - OK, it's a crude version of Intelligo Vim. That's...pretty much it.
Sense Holiness and Unholiness - Well, unlike the others this is gonna be Divine, so it's probably a source of Holy Magic integration. Beyond that, Intelligo magic (already got it) - arguably could be considered a minor Holy Hermetic Virtue "Can Detect Demons with Intelligo" and "Can use Intelligo magic on the Divine and not get in trouble".
Second Sight - Probably one of the sources of Intelligo Vim magic. However, it's ability to ignore Magic Resistance hasn't yet been integrated, as described in Hedge Magic.
Shapeshifter - Pretty much the definition of Muto Corpus (Animal). Already integrated, unless there's something specific to it (like no warp for shapeshifting, or something.) Although Shapeshifter doesn't have the language that Skinchanger has about being detected...so is that an implied virtue right there? (limit of essential nature?)
Skinchanger - (OK, not technically an ability) - Also the definition of Muto Corpus (Animal), although it also includes the ability to create lesser Enchanted Items. The fact that the skinchanger won't degrade mentally is probably an unintegrated minor virtue, though.
Wilderness Sense - Oh, right. This is a Supernatural Ability. Um... Size: Boundary for Intelligo effects is non-ritualized. Further, if the boundary is naturally occurring, (such as a forest, mountain, or lake), you don't need to add size modifiers. The actual size of the boundary does not matter, so long as it is continuous and naturally-occurring. Maximum size would be a mountain range, small sea, or a singular primeval forest.
