# Disease Creation & Custom Diseases

Make your own Nurgle's Blessing! Use Medicae for a crafting test after choosing modifiers. The total of chosen modifiers cannot exceed -60 or +60.

The GM may assign modifiers for existing samples, equipment, or other factors.

## DISEASE ATTRIBUTES (choose one or several)

The toughness test to resist disease effects is challenging (+0). For each additional -10, resisting specific effects may be made more difficult by -10.

* **fever-inducing**: test toughness daily or suffer fatigue equal to failure levels -10
* **hemorrhaging**: test toughness daily or suffer Blood Loss -20
* **collapsing**: test toughness daily or die -30
* **wasting**: test toughness daily or suffer d5 [choose: STR, AGI, TOU, INT, WP] ability damage -10
* **deteriorating**: test toughness daily or suffer d5 [choose: STR, AGI, INT, WP; attn.: not TOU] permanent ability damage -20

## DURATION

* **parasite** - permanent -30
* **viral** - temporary 5d10 days -10
* **bacterial** - temporary d10 days +0

## PERSISTENCE

For each -10 or +10, victims gain the modifier to their toughness tests to resist infection. The baseline modifier to resist infection is +0.

## ANTIBIOTIC RESISTANCE

For each +10 or -10, producing a cure and/or vaccination becomes equally more or less challenging. The baseline modifier and time to produce a vaccine is equal to the difficulty to produce the disease sample.

## INFECTION

* poison (ingestion or injection only) +20
* fluid exchange +10
* touch -10
* airborne -30

## INCUBATION TIME

* fast (day approx.): +0
* medium (week approx.) -10
* slow (month approx.) -20

## GRANDFATHER'S BLESSING

* conduct RITUAL with +0 modifier; gain +10 for each success level for the disease crafting test. Ritualists must resist infection from one of Papa's blessings after a successful ritual. Failure indicates Contempt of the Warp.

## Crafting and time benchmarks

Crafting roll success and failure modifies the time needed to produce a sample one step per level.

Quantity: adjust the time modifier for one step for more samples as per acquisition quantity to craft more samples, with one sample being at +10 to test. Benchmark presumes only one sample is produced.

* +60 6d10 minutes
* +50 d5 hours
* +40 d10 hours
* +30 2d10 hours
* +20 day
* +10 d5 days
* +0 d10 days
* 10 d5 weeks
* 20 2d5 weeks
* 30 d5 months
* 40 2d5 months
* 50 - year
* 60 - d5 years

### Example disease: Iocanthian Groin-Rot

The Groin-Rot transmits only by exchange of fluids (+10).

The first symptoms begin only after a month or so, making it hard to detect and easy to spread by accident (-20).

The effects of the parasite are painfully permanent (-30), making the victim suffer permanent d5 Strength damage daily if a Toughness test is failed (-20) and a high fever if another Toughness test is failed (-10).

The fever is particularly persistent, making the roll to resist it -10 more difficult (-10). Luckily, the infection can usually be resisted by fit individuals (+20 to resistance), and the Iocanthian shamans have found many herbs to treat the parasite (+10 to antidote).

**TOTAL MODIFIER TO CRAFT**: -40 Medicae test and 2d5 months of work to produce one (+10) working sample.
