Priests, imams, and devout mortals know instinctively that there is
  something horribly wrong, even unholy, about you, and react 
  accordingly.

Your breath smells of dried blood and death, and cannot be covered
  up.

Mortals are instinctively uneasy around you as your predatorial
  nature activates their instinctive flight or fight response. You are at -1 
  in all social interactions with mortals.

Your dead body is particularly susceptible to burning, and once lit
  by any size flame will burst into a raging fire that inflicts 2 aggravated 
  points of damage per round, causing near-unavoidable fear frenzy (you give 
  away advantage and cannot gain it back, though the +3/wp still applies), 
  until extinguished.

On nights of the full moon you lose control of your Beast. You
  automatically rage frenzy on these nights. All night.

You cast no visible reflection in mirrors, water, or shiny surfaces,
  though you will still be picked up by photography and video even if those 
  devices use a mirror.

You resemble a corpse much more than is usual in a vampire,
  including visible veins and a sickly pallor. All skill at Masquerade is 
  lost, and purchasing skill in Masquerade is double cost.

You must acquire permission from someone before entering their home
  for the first time unless you are invited in by another resident.

You cannot stand the sight of a cross or similar holy symbol and
  must spend a willpower point merely to remain in the presence of one. 
  Approach or attack is out of the question.

You are repelled by garlic and cannot approach it. The presence of
  Garlic will force you to spend a willpower or flee its presence. It does 
  not harm you, however.

You cannot cross running water, such as rivers, streams, or running
  storm drains without expending a willpower point. You can step over a curb 
  that has water running along it, but it makes you uneasy.

Your feeding is restricted to one particular type of prey. For
  whatever reason, you believe you cannot tolerate vitae of other types, and 
  you will become very ill if you consume blood of an origin you cannot 
  determine to be within your prey-class. Your prey-class must be described 
  in your character background, and it must be sufficiently restrictive to 
  exclude at least 60% of possible prey.

You cannot awake during the day under any circumstances.

You are sensitive not only to sunlight, but to intense ultraviolet
  radiation such as sunlamps. Treat strong UV light as sunlight for all 
  purposes.

You may not tread on Holy Ground, including churches and
  cemeteries.

Mortals do not feel ecstasy at your bite, and will react as if
  bitten by a wild animal, including fighting back. This makes hunting much 
  more difficult.

Damage inflicted upon you by silver weapons is aggravated, and the
  touch of silver causes you pain.

Plants wither, become sickly, and perhaps die when you touch them.
Animals find your presence disturbing, avoiding you or attacking you in a
  greater than usual manner for a vampire. This will make it more difficult 
  to use the ANIMAL hunting method.

Your touch is just above freezing on direct contact. Air within a
  foot of your presence is noticeably cold. Moisture condenses on glass. 
  Mortals' exhaled breath is visible. In many situations this will make the 
  Masquerade difficult without dramatic precautions.

You cast no shadow, no matter how bright a light you stand in front
  of.

You have lost the ability to retract your fangs. When you smile,
  your vampiric nature is plain for everyone to see.

Your eyes have become like those of a serpent or cat. Yellow and
  slitted, they shine faintly in the darkness, and are quite obviously not 
  the result of contact lenses. This does not give you any vision beyond 
  normal, but may prove a disadvantage in stealth, and certainly will be a 
  problem for the Masquerade.

Blood is not enough for your nourishment. When you hunt, you must
  also consume the flesh of your victims. The Don Juan method is forever 
  barred to you, unless you find yourself a truly degenerate herd. And even 
  then, how long will they last? Note that this does not allow the ingestion 
  of any other sort of food, even flesh that is consumed outside the act of 
  the hunt.

You are unable to pass a bowl, pot, or similar open-top container of
  rice or other uncooked grain without stopping to count each individual 
  grain. Tearing yourself away from this task and turning back requires the 
  expenditure of a willpower point, but you will be unable to pass the 
  container until you have completed counting.
