SEXUALIS MORBUS (SEXUAL DISEASES)

This system does not attempt a specific treatment of a subject which is beyond its scope and purpose. What is done, however, is to give general categories of disease and maladies and their game effects.

Chance Of Contracting A Disease

To contract a sexual disease, the character must be having sex with somebody who already is inflicted with a disease. The base chance for contracting a natural disease is 1% per round of sexual activity. The base chance for contracting a magical disease is 2% per round of sexual activity. Modifiers are as followed:

Constitution of character
1-3 +4 13-15 -2
4-6 +2 16-18 -4

     Constitution of character
      1-3    +4     13-15  -2
      4-6    +2     16-18  -4

protected intercourse / 2 (cuts the chance in half)
unprotected intercourse X 2 (doubles the chance)

Thus, Rath (con. 14) becomes intimate with a person that has a natural sexual disease unfortunately he prefers not to use protection (like a sheep-skin condom). He participates in 18 rounds of sex. His chance of getting a disease is 32% (18-2 X 2). He rolls a 28 on the percentile dice. Thus, our hero now is infected with a sexual disease. If only he used protection, his chance of contracting a disease would have been a mere 8%. A lesson to be learned.

The use of Protection From Disease and Cure Disease spells are of course very useful for preventing and curing disease.

Random Determination Of Who Is Diseased

The GM should decide of the person a character has sex with is infested with a disease, but if he wants to decide randomly, this system is provided. The chance of a prostitute having a disease is already established if Getting To Know A Prostitute (Random Generator) section of the guide is used. Therefore, the system is provided for non-prostitute people. Also, this system doesn't handle whether diseases are natural or magical because some GM's may have magically rich campaigns ands others may not so odds may vary.

The base chance of having a disease is depend on the size of the settlement (the theory is that more diseases are found in bigger settlements where more people interrelate):

Thorp, Dorf 10
Hamlet 25
Village, Wych 30
Town 35
City 40

     Thorp, Dorf     10
     Hamlet          25
     Village, Wych   30
     Town            35
     City            40

Modifiers to the base chance are by social level (the theory is that more disease are transmitted amongst the lower classes because there are dirtier and less careful):

Lower Lower Class +20
Middle Lower Class +15
Upper Lower Class +10
Lower Middle Class +5
Middle Middle Class 0
Upper Middle Class -5
Lower Upper Class -10
Middle Upper Class -15
Upper Upper Class -20

NOTE: not all settlements have these many variations of social level. The GM should be aware of what social levels are around.

     Lower Lower Class   +20                 NOTE: not all settlements
     Middle Lower Class  +15                 have these many variations
     Upper Lower Class   +10                 of social level. The GM
     Lower Middle Class   +5                 should be aware of what
     Middle Middle Class   0                 social levels are around. 
     Upper Middle Class   -5
     Lower Upper Class   -10
     Middle Upper Class  -15
     Upper Upper Class   -20

Thus, a lower lower class citizen of a city would have a 60% chance of having a disease maybe because she sleeps around to get extra food money. In a near by hamlet, an upper upper class citizen would have a 5% chance maybe because he has a private mistress to engage in sexual activity when he is up to it. While in the city, a citizen of equal status has a 20% chance maybe because he parties a lot with the rich and he screws just as much.

At first glance at this system, a person might assume that in a city 9,000 roughly 40% (3,600) of the population are sexually diseased. The first item to note is that this system includes only those that ENGAGE in sexual activity. This eliminates a large amount of the city including children, elderly, etc.. We'll say that half the city engages in sexual activity, which seems like a lot. Social level is another important aspect that must be included. Thus in this example, let us assume that all social levels exist and there population is equal:

                           Total   Sexual   Chance    Total Of
     Social Level          Pop.    Active   Of Dis.   Diseased
     Lower Lower Class     1,000    500   *   60%   =   300
     Middle Lower Class    1,000    500   *   55%   =   275
     Upper Lower Class     1,000    500   *   50%   =   250
     Lower Middle Class    1,000    500   *   45%   =   225
     Middle Middle Class   1,000    500   *   40%   =   200
     Upper Middle Class    1,000    500   *   35%   =   175
     Lower Upper Class     1,000    500   *   30%   =   150
     Middle Upper Class    1,000    500   *   25%   =   125
     Upper Upper Class     1,000    500   *   20%   =   100
                                                       -----
                                                       1800
Thus, 1,800 people of 4,500 people who have sex of 9,000 people that live in the city are infected with a sexual disease. This is a lot, but we're assuming that those that participate in sexual activity do this with more than one person. The thing to keep in mind is that this system is to calculate individual persons, not mass population. When the dice starts rolling, the results usually don't go with the odds.

Natural

Natural sexual diseases might not seem as bad as magical, but they are as terrible. After choosing the desired disease on Table 1, the GM should roll 1d8 to decide occurrence and 1d8 to decide the severity of the disease.

Table 1: Natural Diseases
Occurrence Severity
Name Acute Chronic Mild Severe Terminal
E.S.S. 1-4 5-8 1-3 4-5 6-8
Gonorrhea 1-6 7-8 1-5 6-7 8
Insania 1-4 5-8 X X X
Prurire 1-7 8 1-6 7-8 X
Segmen Neus 1-4 5-8 1-3 4-5 6-8
Syphilis X 1-8 1-5 6-7 8
Tuna 1 2-8 1-8 X X

 E.S.S.               1-4    5-8       1-3    4-5      6-8
 Gonorrhea            1-6    7-8       1-5    6-7       8
 Insania              1-4    5-8        X      X        X
 Prurire              1-7     8        1-6    7-8       X
 Segmen Neus          1-4    5-8       1-3    4-5      6-8
 Syphilis              X     1-8       1-5    6-7       8
 Tuna                  1     2-8       1-8     X        X

Occurrence determines whether the disease is a single (acute) attack or whether the disease will recur periodically once contracted (chronic). Chronic maladies will affect the character periodically, if they occur at the same time as any other malady (disease, disorder, or parasitic infestation), the severity of both will be increased. Thus, if two chronic maladies are contracted, the character is not likely to survive another disease attack.

Severity refers to the seriousness of the disease, disorder, or parasitic infestation and determines the period of disability (recover time or length of illness which terminates in the character's demise) and the effects of the malady.

Description

Magical

It is unknown how these magical diseases came about. Some sages say they're from war, some say that a rip in magical fields caused them, others say that creatures having sex with certain magical beings cause weird things. Whatever the reason, magical diseases aren't pretty. Magical diseases don't have an occurrence or severity. They last until dispelled by cure disease, wish, etc.. The GM can pick or roll (2d8) on Table 3.

Some may feel that the these diseases cause to much damage. A first level character can have sex with somebody infected with acid secretion and most likely be killed during the encounter. This is true, but the important thing to remember is that these diseases are magical and are not necessarily that common in society.
