Zombie is a stage where the bearer ceases to depend on a living body.
Turning into a zombie grants its special variety: with powerful defense, strength, and spell-like abilities. The traits and skills of the previous stage meanwhile remain without noticeable changes — the Prisoner's path grows not in breadth, but in depth.
The canon adds to the description a line that matters more to this path than any list of abilities: the bearer constantly struggles with the desires in their heart and with the strong malice within. The sixth stage does not ease this struggle, it merely makes the body more resilient to its consequences.
The composition is frankly dead-like: the heart of a zombie, ninety grams of flesh and blood of a living person, thirty — of a dead one, an eyeball of a zombie, and three lunar flowers.
The coexistence of living and dead flesh in a single formula is a precise image of the stage: the bearer stands exactly between the one and the other.
