I agree in principle, but in this case all I'm concerned about with the spirit is for it to report on active astral signatures and auras; if it were to find the house encircled by wards, that would tell me any further recon would most likely be pointless. It would also be able to report on any active spirits, which would alert me to the fact that I'd need to be cautious. I don't think that's particularly dangerous as the Astral is supposed to be quite alive, and with trees and shrubbery around there should be enough ambient life to make it harder for the spirit to stand out, especially since it's a Spirit of Earth.

Damn, those are some large houses! And this just goes to show why Astral Clairvoyance doesn't hold a candle to true Astral Projection; while perfect for looking around corners and popping into rooms around you, the range limitation can be a pretty significant limiting factor.
All right, looks like I'll have to take a drive into the cul-de-sac of the target building after all, but let's take things one step at a time.
Re: hits on Astral Clairvoyance. The rules for Passive detection spell does indeed state that hits become the limit for any perception tests while the spell is sustained, which makes a lot of sense. Specifically:
While the spell is sustained, Perception Tests using this sense have a limit equal to the net successes from casting of the spell instead of the subject’s Mental limit.
That is much clearer, and explains why you would ever need any more than a single hit on the spell. So any Assensing I'm doing is done with 4 as a limit instead of my Astral limit (presumably, since Mental limit doesn't apply to assensing). And no, it is not like Projecting at all; think of it as moving your point of "view" from one place to another, like if you were looking through a camera instead of your real eyes. In this case, it's Astral Perception, however, so the normal caveats about "sight" remains, and any ward stops me dead in the water as I have no means around them. I also don't get any other benefits of Projection such as being able to move halfway across the world in an instant, but no drawbacks like losing track of my body and having an aura at the point of perception that can be targeted with Mana spells either.
Loving the detail on Detect Life and Spatial Sense! Gives me a good sense of the place and it's surrounding neighbours, so I'll add this to the writeup. No further questions on the sleeping human, that seems like it would be appropriate for Detect Life; I will want to know more, of course, but that's what Assensing is for, which in this case means ordering the car to drive around the cul-de-sac in front of the house so I can get my astral self into the master bed room. Even with these large houses it looks like I'll be able to do so from the opposite side while the car drives slowly past the front driveway.
And the Spirit will not be going inside; well, actually, I guess that's for you to decide because I forgot to specify that, and I can image Jaeger being a little forgetful about minor details like that; as per the above, he will have asked it to report on any astral signatures and auras in the target location. Let me know if it sets off a masked alarm ward by doing so, however, as that changes the following part quite dramatically

Assuming the spirit doesn't set off any alarms, it would return and report back what it found as per the above, and then Jaeger would go there in person and do everything above. The only thing left is Assensing the house and the human being; as per our previous discussions on this, I'll roll once for the house and once for the living being, as one is a place and the other is an actual aura. I'd like to get a sense of both, so if I wanted a spirit to do that I'd count that as two of the Force auras it could assense in one service. Sound fair?
Assensing (Aura Reading) 6 (+2) + Intuition 4 - 2 for sustaining Astral Clairvoyance for a total of 10 dice, with a limit of 4 hits from Astral Clairvoyance.
Assensing house [4]; Assensing human [4]:
10d6t5 5 10d6t5 5Heh, well, that went better than expected. I can only keep 4 hits in either case, but that should give me about as much information as I can expect, unless the individual is actually Awakened and has any number of metamagics like Masking or whatever that allows him to resist. Do you want me to roll a memory test to commit the aura to memory? I might need it later for the purposes of using Astral Doppleganger if this turns out to be a person of interest.
I'm hoping that I'll be able to find some sort of clue as to who this person is; i.e. does the aura remind me of the one described by the spirit the other night (i.e. is it Kreutz himself), does it have similar augmentations, etc.
