#but also yeah so I do think there's a bunch of crap necros out there too

Harrow is exceptional but I'm pretty sure the average bone adept can raise a skeleton easy enough. Harrow's OP status is more the fact she can raise a skeleton from a single finger bone. Very few bone adepts can do as much with as little as Harrow can.

The standard Ninth cavalier wears panniers to carry around kilos of bone for their necro to use. Gideon doesn't have to though, because Harrow doesn't need that. She could conquer the average town with nothing but the contents of her pockets.

Fighting the average bone adept is "two skeletons burst out of a corpse and shamble towards you". Fighting Harrow is "weird looking goth kid throws some dice (?) on the floor, they transform into a battalion of skeleton soldiers moving in perfect lockstep before pulling you all apart".

Most adepts can do the standard tricks of their houses I think, but you're 100% right that we've mostly seen either the absolute cream of the crop: some of the most talented necros in the system (and also Judith) or fucking lyctors. Most are not nearly as good at them.

But even the Ninth had spirit callers who could bring Wake back for a few seconds. Abigail is special because while your average Fifth can call someone 400 years dead with their bones, Abigail could do it with one of their old socks. Dr Sex was dead for like 250-300 years when some Fifth academic called him back, which wasn't considered particularly noteworthy (merely rude, let the man rest).

BoE still make headway though because they use guerrilla tactics and specialist knowledge. They know not to fight head on if they can avoid it, and they know what can make it all go terribly wrong (e.g. sniping someone who's not the necro). And also because, well, outside the Dominicus system necromancers are a lot weaker. There's just so much less ambient thanergy to work with, hence the need for fresh deaths. Without those to power them, a necro on a thalergenic planet is just a nerd who gets out of breath tying their shoes.

The Nine Houses must be absolutely terrifying to fight.

And not just because their invasions start with a drop ship full of pimply 14 year olds inexplicably armed with zweihanders whose entire remit is to cause a mass casualty event for necromantic purposes...

We're mostly introduced to the schools of necromancy at the beginning of GTN, before we have broader context beyond "ooh, new magic system." But if you think about it in light of what we later learn about the Cohort:

Second House: they can literally drain your life force to power up their cavaliers. "It’s said they all die screaming"

Third House: that pile of corpses in no man's land? They're being used as a power up. Also, someone's just rearranged your face; your arse is on backwards.

Fourth House: that pile of corpses in no man's land? They're bombs now. And if you corner a Fourth House necro, they're a bomb too!

Fifth House: at best, they're the weird technicians for the Houses' horrifying blood and monolith based FTL system. At worst, it doesn't matter if you kill yourself to avoid capture or if you hold out under interrogation until you expire, they can still interrogate your ghost.

Sixth House: drop a cigarette or shed a hair on a clandestine operation? These guys now know your age, shoe size, and approximate location. They know what you had for breakfast. They know what you held in the last 12 hours.

Seventh House: that pile of corpses in no man's land? They're armed and marching on you now.

Eigth House: why is he glowing? WHY IS HE GLOWING?!

Ninth House: the guy next to you's bones just became an IED.
