Becoming a vampire is similarly difficult, and as was already said but may be re-iterated, that is why there is a vampire religion and people roleplaying as vampires. They are slowly preparing themselves and the environment for later incarnation in the spot where they can become the real immortal elite.

"Soulless incarnation" seems to also be a thing, although it's a difficult concept to nail down because it sound contradictive. It means the person incarnates a part of themselves which equates to the autonomous nervous system, or the subconscious. There is no direct awareness in the soul or body, but it acts as the real person would have. This can also be done as a way to wedge into hives of soulless beast-humans, where there is just enough of the proper blood to incarnate this shard for now, but not enough to actually live there with full on frontal awareness. Maybe one can then move in later after the environment settles, or the experiences are just taken out again with the soul being removed, having learned some fringe skills of the subconscious.
