There was a big difference between advancing without the Tomes versus advancing with the Tomes.
Advancing into the Second Realm without the Tomes was very easy. Nobody failed it.
Yet, advancing with the Tomes made it much harder, and there were cases of people failing the advancement.
Failing an advancement was a huge hit to one's wealth, Momentum, ego, and time.
If one failed, they would fall back into the Late First Realm. Even more, they would have to buy the Tomes again.
Failing an advancement was a major setback, and some people never tried again since it had been so hard to get here in the first place.
The reason why it was so different to advance with Tomes was that the Tomes changed the body in an unnatural way.
The Tomes were infusing the advancing person with Ether it wasn't designed to absorb.
This meant that the body had to adapt to this new kind of Ether.
