Although he was given all the necessary information, Levi wanted to be as precise as possible.
He knew that a simple mistake in any of the three Stages of creating an Evolutionary Formula would put both Shia and Blee'der into a whole world of agony.
That's because the final formula's job wasn't to break through the plateau like it was some sort of magical elixir.
It was used as a way to unseal the stagnated evolutionary traits based on the materials used for the formula. Then, the Shadowlife seed would take it from there and evolve the Nightcrawler through the chosen unsealed evolutionary traits.
If the formula were flawless, all the evolutionary traits from Tier 2 to Tier 3 would be unsealed, allowing the Shadowlife seed to commence the so-called perfect evolution.
If it was great, but not perfect, a high number of evolutionary traits would be unlocked while the remaining ones would be sealed forever...This was called Remarkable Evolution.
