[Sending is like this, you do not have to be a witch to get one though you do have to be a witch to reject one or block somebody.]
"Identify starts with just, what is that or who is that, very spare blurb, public information - gets you the king of Lunabella's name and occupation, does not get you the private citizen on the street unless he has introduced himself to you. At rank two, it gets you active magic - enchantments on items, curses on people, with enough practice you can tell whether a null result here means no magic or that they're protected from divination, but tricky. Rank three and you do not have to do this consciously every time, you can have a - what is it called - heads up display if you like, or some other means of reminder, whenever you see a thing, and it also lets you pick out friend or foe. Rank four and you get Mr. Private Citizen's name - and his address and his family members and his witch build if he's got one though not his complications, and suchlike. Rank five does True Names, those are useful for some magics. If you identify a magic you also identify who cast it. Complications become identifiable. Reveals what they think of you and your allies, whether they are friendly or not so much.
"Status at rank two lets you know if someone is, say, injured, sick, cursed. Not very specific. Might not include everything, if they have a lot wrong with them. Rank three, more specific - if they are sick, what with and for how long. If they are injured, what by and how long ago. Rank four, adds whodunnit, prognosis, and some hints on how to fix it with the powers you have. Rank five, combines with Map and can get mighty specific even on an enemy - what are they casting, what are they thinking about doing.
"Augury starts at thirty minutes at rank two and just good-bad-neutral. Goes up to twelve hours, then forty-eight hours plus you can get bad omens of big bad stuff a month out, and if you try you can get auguries about how things will be for other people - touch range, hard to do without them knowing. Rank five it's a week, omens for a year, catastrophes five years, apocalypse a hundred - everybody hops to when the bigshot diviners all say we are ninety-nine years from doom - and you can narrow down omens with more castings of Augury, and try to get good omens as well as bad, though that is back to yes-no-maybe granularities for things like 'will I find love' or 'will I beat up my witch hunter'.
"Map starting at three can passively rack up information about wherever you are. You can identify the stuff later. Look at it in lots of possible formats, like this -" She Sendings an aerial shot, an atlas-like simplified rendering, and a 3D view of the same Lunabella market square. "Does not automatically update with who is there when you are not there, but you can be like, that lady selling the gyros, what is her deal, and get back that she does not know you are alive and she sells gyros and is called Sosipatra because that's the name on the stall and it's so public. At four, it can work retroactively, even places you have been as a human, automatically identifies everything in it, no focusing to keep it going. Five, that picture of the square on Lunabella I have would be live-updated like a security camera! Also possible to astral project to anywhere you have mapped and go for a mapping jaunt from there in new directions you did not go last time.
"Archive is like photographic memory. Keep track of things you have looked at, or stuff you own, or things in your hat. At four, slurp up a whole book you can touch, search it like you are a grep. At five, works through maps, walk into an unwarded library once and it is all yours. Shareable full sensory experiences.
"Foresight starts with needing a ritual chant, not too time-consuming, starts at half-second of shadows of where things will be. At rank four, a second and a half; if you are really focused, so probably not in a fight, you can do a whole hour, but it does not account for anything you do not know about, if the Spanish Inquisition is about to show up this will not appear in your foresight, just some distortion you cannot place well. At five, three seconds, includes tactile, and the focused thing is a whole day and the distortions are a little more usable to figure out what's what. Also stick your foresight to an omen for more information about what the fuck. None of this is set in stone, you can use it to change things.
"Lock-on is basically what it sounds like, target stuff from map data. Doesn't make spells too maneuverable, think like a paper airplane if you could blow on it, but improves range a lot.
"Masking is the anti-Map spell. Only comes in at rank 5 but anything very sensitive has a fancy diviner to do it for them."
