GURPS - Compendium 1..

In a campaign where there are different forms of travel with
different effects, use the disadvantage value for the least harmful
common method of travel. A character who gains access to a form
of travel without side effects should be required to buy off his
Timesickness disadvantage.
For game purposes, the malady will be described in terms of a
disadvantage. To find the point value of a given level of
Timesickness, multiply the severity of the effect by the frequency
with which it affects the victim, as follows:
Severity
Nuisance: The victim is mentally stunned, as per p. B111,
and rolls for recovery at -5 with only one attempt allowed per
ten seconds. This will have little effect unless the travelers
arrive in the middle of a hostile situation. -2 points.
Mild: The victim is mentally stunned and takes 2 dice of
Fatigue (see p. Bl17). -5 points.
Severe: The victim must make a HT roll. On a success, he is
mentally Stunned for 1dxl0 minutes. On a failure, he is Stunned
for 1d hours. Double this on a critical failure! -10 points.
Very severe: As above, but the victim also takes damage: 1
HT if the duration is under an hour, 2 if it is an hour or more. -
15 points.
Nightmare: This is a mental effect, most appropriate for
psionic time travel. On a missed Will roll, the victim has monstrous
visions. Go to the Fright Table and roll as though he had
just missed a Fright Check by twice that amount. -15 points.
Critical: The victim takes 1 die of damage, and makes a HT
roll (even if the save was on Will); if failed, he takes another
die. Shock and knockdown effects are exactly as normal injury
(crippling is ignored, however). This can kill you. -20 points.
Frequency
Rare: Travelers are affected on a critical failure only. Half
value.
Frequent: Any failure affects a traveler. Normal value.
Very frequent: A critical success is required to avoid effects.
Multiply value by 1.5 and round up.
Acute: No saving roll allowed; all travelers are automatically
affected unless they are immune. Double value.
Generally, the more common Timesickness is, the less severe it
should be. This disadvantage can only be taken in a campaign
where time travel, dimension travel and the like are common
occurrences.
Tourette's Syndrome
Variable
You suffer from Tourette's Syndrome, a rare neurological
disorder that causes your muscles to twitch and contort uncontrollably.
It also causes you to make uncontrollable vocalizations,
which can range from incoherent grunts and "barks" to
foul language.
At the -15-point level, your affliction is obvious to anybody
who observes you for more than a few seconds. You are at a -2
to all DX rolls, and any tasks requiring fine manipulation take
twice the normal time for you to finish. Certain social skills
(Acting, Bard, Leadership, Sex Appeal) will be negatively
affected as well, in certain situations (GM's option).
At -30 points you find it very difficult to function at all in
normal society. You are at -5 to all DX rolls, your movement
rate is halved, and tasks requiring fine manipulation take five
times as long to complete. Social skills are affected as above,
but to an even more extreme degree.
Some skills (Stealth, Running, Acrobatics) will be completely
impossible for you, and others will be practically useless. For
example, certain combat skills could be studied in theory, and
even practiced for conditioning purposes, but would be of little
benefit in an actual fight.
Sometimes, the symptoms of the disease are acutely embarrassing
to the victim. They might be perversely comical, requiring
anybody who's in his presence to make a Will roll to avoid
bursting into helpless, uncontrollable laughter (individuals with
the Unfazeable advantage get a +3 to this roll). Another embarrassing
complication is when your involuntary vocalization
takes the form of offensive profanity. If a character has either or
both of these difficulties, it adds an extra -5 to the advantage.
Unfit
-5 points
An Unfit character will lose Fatigue points at twice the normal
rate, but will recover Fatigue points at the normal rate. (This
applies only to Fatigue lost to exertion, heat, etc.; it has no effect
on the Fatigue used to power psi or magic spells.) All HT rolls are
made at -1.
Unnatural Feature
-5 points per feature
This is for characters who are essentially human-looking, but
who possess one or more disturbing features - be they due to a
magical curse, ultra-tech surgery or a strange disease. Examples
include pointed ears, glowing red eyes and shiny metallic fangs.
This does not have to be a physical feature; the sound of the
voice or the intensity of the gaze could qualify, if intense
enough to require concealment.
Very Unfit
-15 points
A Very Unfit character will recover Fatigue points at only
half the normal rate, as well as los ing Fatigue points at twice the
normal rate. (This applies only to Fatigue lost to exertion, heat,
etc.; it has no effect on the Fatigue used to power psi or magic
spells.) All HT rolls are made at -2. A Very Unfit character cannot
have the Immunity to Disease advantage, regardless of his actual
HT score.
Weak Immune System
-30 points
You have poor resistance to disease and infection. HT rolls to
resist specific diseases or infections are at -3 to HT or against HT
9, whichever is less. The first two levels of Panimmunity (see
p. 28) have half their normal effect; you may not take the
Disease-Resistant or Immunity to Disease advantages, or benefit
from the third level of Panimmunity.
Unless you take special precautions (for instance, remain in a
sealed environment or wear air-tight clothing when you leave
one), the GM should require an unmodified HT roll to avoid
coming down with a potentially serious disease every month.
Although not necessarily fatal (especially with high-tech medicine)
this will take you out of the action and force you to spend
additional money on drugs and hospital treatment.
