I worked it, heavily edited to suit me and because I think props are largely unnecessary. For the things that are worth having, like an altar, you can imbue this with the energies wanted in multiple ways - you read between the lines to understand the goal and figure out your way to get there.
I will add this, and it’s totally UPG - the Akasha Subterfuge is nothing but a large and nasty parasite, it has no power other than what it takes from you and those that foolishly worked with it, don’t bother calling it unless you are confident you can control it, but it’s kinda useless so I wouldn’t bother.
It’s the main reason Abiel got so sick as it was feeding off him, and he wasn’t good enough to tell the difference between that and that fact that he didn’t cleanse the energy of decay from his qi body properly - newsflash, if you suck in the energy of decay, it decays you, that’s why vampires create cleansing and filtering techniques for feeding, so that if they suck in the energy of sickness from a target, they don’t get get that sickness. Abiel failed to understand this basic piece of energy working.
The whole book left me very unimpressed - way too much romanticizing and it obscures and leaves out what’s important about the dead - they’re humans without bodies - as complex and nice or evil as humans can be, with all the usual psychological issues that come with that. When you already know how to summon an entity, what you really want is a psychology book on communicating with difficult people. 
If you want fun necromancy techniques I do recommend Sorceress Cagliatros early works. Her understanding of the dead as people and how being dead affects them personally is accurate and she explains it well.
