Corruption and Madness: The Slow Slide into Darkness

The Nature of Corruption: Your Soul Has Hit Points

In the Old World, your body isn't the only thing that can be damaged. Corruption represents the slow erosion of your soul, humanity, and sanity. It's like rust for your spirit—invisible at first, but eventually it eats through everything. Unlike wounds that heal, corruption accumulates, marking your descent into something... else.

Mutations: When Your Body Betrays You

Mutations are Chaos's calling cards—physical manifestations of spiritual corruption. They range from "easily hidden" to "burn the witch!" Some might even be useful, which makes them all the more insidious.

Removing Corruption: The Nearly Impossible Task

Getting rid of corruption is like trying to unbake a cake—theoretically possible, practically unlikely. Most methods are temporary, dangerous, or require divine intervention.

Methods to Reduce Corruption:

Note: Mutations cannot be removed except by divine miracle or amputation!

Real Play Example: The Corruption Spiral

Gottfried's Descent:

Session 1: Touched a strange green stone in the sewers (GM: "Roll 1d10 corruption")

Result: 7 corruption points. "Your fingers tingle unpleasantly."


Session 5: Fought cultists using dark magic (GM: "Everyone witnessing gains 1 corruption")

Total: 8 corruption. "Your dreams are filled with whispers."


Session 8: Read a forbidden book to find clues (GM: "That's 1d10 corruption")

Result: 5 more points. Total: 13. "Roll for your first mutation..."

Mutation: 67 - Extra Mouth. "A second mouth opens on your neck. It whispers constantly."


Session 12: Used daemon weapon in desperation (GM: "1d10 corruption per hit")

Result: Three hits, 18 more corruption. Total: 31.

Outcome: "Your body convulses. Roll a new character. Gottfried is now a Chaos Spawn."

The Psychology of Corruption

Corruption isn't just mechanical—it's a roleplaying opportunity. As corruption accumulates, characters should exhibit changes:

"I can still remember when the voices started. Now I can't remember when they stopped
being voices and became my thoughts."
