Except pretty much every usage of actual Reaper technology - indoctrination, the Reaper corpse being 'alive', the Human-Reaper construction, turning the Protheans into Collectors, dragon's teeth - all pretty much qualifies as the "so far advanced it may as well be magic" when compared to any other piece of Mass effect technology. Only the Mass Effect idea itself is really explained in depth - all the rest is just estimation.
