R8A4 (R8A4 Calcifying Pathogen) is a CLASS II calcifying pathogen contained within Centum Laboratories. It causes progressive tissue petrification and eventual organ failure.

Pathology

Stages of Infection

Stage	Timeframe	Symptoms
Stage 1	~2–4 seconds	Initial infection. No visible symptoms during incubation.
Stage 2	~3–4 seconds per limb	Calcification begins from infection point. Skin turns grey as tissue petrifies, spreading to adjacent body parts.
Stage 3	~60–80 seconds	Full body calcification. Max health increases by 100. Tissue classified as non-flesh.
Stage 4	~35 seconds after Stage 3	Rapid health deterioration. Progressive health loss until death.

Transmission

Direct contact — touch transmission
Airborne — coughing every 4–12 seconds

Incubation

2–4 seconds initial
Full calcification: ~60–80 seconds
Death after calcification: ~35 seconds

Detection Window: 8–16 seconds

Description

The infection spreads from the initial point of contact throughout the body, turning skin grey and petrifying tissue. The temporary health increase during Stage 3 can be misleading, as the rapid deterioration in Stage 4 is invariably fatal without treatment.
