GURPS - Compendium 1..

Unhealing
-20/-30 points
You do not normally regenerate injury at all, and get no daily
HT roll to recover lost HT - even when under the care of a
physician. First Aid still works normally to treat bleeding, or the
shock of a wound, but it cannot restore lost Hit Points. Magical
or psionic healing will function normally, however.
If you can regenerate lost HT normally when certain conditions
are met (e.g., when immersed in blood, bathed in lava,
etc.), or by stealing others' HT with the Bite advantage, magic or
psionics, then this disadvantage is worth -20 points. If you can
never heal naturally, it is worth -30 points.
Note: This disadvantage is normally only appropriate for
highly-unnatural beings, such as the undead.
Unusual Biochemistry
-5 points
Your biochemistry, while still enabling you to subsist on
human food and water, is different enough from that of humans
that drugs that work on humans have reduced or unpredictable
effects.
When a drug is given to you, roll 1d. On a roll of 1-3 the
drug has normal effect. On a roll of 4-5, it has its normal effect
combined with an additional negative effect: lose 1d Fatigue
(sickness and nausea) or, at the GM's option, enhance any negative
side-effects of the drug. On a 6, the drug no effect at all. A
biochemist with a lab can manufacture variants of normal drugs
that are specific to your biochemistry, but these drugs cost ten
times as much as usual.
Vampiric Dependency
-50 points
You are a "human vampire." You are not a supernatural
monster - you suffer from a genetic condition (supposedly common
in certain Eastern-European countries) that requires you to
derive sustenance from human blood.
You do not actually drink blood; rather you filter it, through
special glands in your extended canine teeth. If carefully done,
this can be accomplished with no harm to your donor whatsoever.
If you drink the blood of a drunken individual, or someone on
drugs, you will yourself become drunk or high. Drunks who have
their blood filtered by a vampire will normally not have a
hangover the next day. Roll 3d the first time any character's
blood is filtered while drunk - on a natural 18 that character's
hangover is doubled in severity and duration, even if he has the
No Hangover or Light Hangover advantages. On a 3-17, the
hangover is completely avoided.
You may eat nothing except raw, fresh meat. At least once a
week - preferably more often - you must filter approximately a
quart of fresh human blood (remember that the blood does not
need to be removed from its donor to be used). If the GM
prefers, he may require vampiric characters to eat only small
living creatures, or some other similar restriction of his own
choosing.
Vulnerability
Variable
You take extra damage from certain forms of attack, or are
weakened and hurt every time you merely come within a certain
distance of a substance. For each level of Vulnerability purchased,
you take an extra 1d damage (for attacks doing less than
1d damage, multiply the damage by the level of vulnerability).
This extra damage is added to the usual damage of the attack,
before any DR is subtracted.
You cannot take a Vulnerability to anything that you have
Invulnerability, Absorption or Reflection against. For characters
with Vampiric Invulnerability (see p. 70), one level of
Vulnerability to something cancels the Invulnerability's effects
for that item or substance. Additional levels of Vulnerability
will do damage, as above.
The value per level depends on how common the substance is:
Very rare: -3 points per level.
Rare: -5 points per level.
Occasional: -10 points per level.
Common: -15 points per level.
See the Defense Table, p. 49, for examples of attack forms;
the GM decides upon the rarity of the substance.
If you are affected by merely being near the substance, add
10% per hex of range to the cost per level. DR does not help
against this damage. If you are hit with an object you take damage
from just by being near, you add the physical damage to the
Vulnerability.
If damage comes off of Fatigue rather than Hit Points, the
total value is halved.
Example: Water Wyrms take 4d damage whenever they're
within 5 hexes of a certain glowing green rock. The green rock is
"very rare," making the cost -3 points per level; however, 5
hexes add 50% to that cost, making the cost per level -4 1/2.
The Wyrms have four levels of Vulnerability, so the total value
comes to -18.
Weakness
Variable
This is like a Vulnerability, but less severe. A Weakness is a
sensitivity, not to any kind of attack as such, but to the presence of
a common substance or condition. It cannot be a food item or
something equally easy to avoid. The more quickly you take
damage, the more the Weakness is worth:
1d per minute: -20 points.
1d per 5 minutes: -10 points.
1d per 30 minutes: -5 points.
Halve the value if the damage done is only Fatigue or Stun.
The rarity of the weakening condition also affects the value
of the weakness:
Rare (exotic radiation or minerals): half value.
Occasional (microwave radiation, intense normal cold, airborne
pollen): listed value.
Common (smoke, nearby magic, horses, loud noises): double
value.
Very common (sunlight, living plants): triple value.
