Vampires are social creatures of the night, introduced to The Sims 3 in The Sims 3: Late Night and expanded upon in The Sims 3: Supernatural. Vampires have a number of special traits and abilities which set them apart from normal Sims and from the vampires of The Sims 2: Nightlife.
Vampires of The Sims 3-era are based on a more modern interpretation of vampires, instead of the more classically-inspired vampires of The Sims 2. They have a pale, slightly glowing skin tone, fangs, glowing eyes, and the optional neck tattoo from the Sims clothing accessories. When they sleep, vampires snore V's instead of Z's.
A vampire's hunger motive is replaced with thirst and all of their needs bars become purple. Thirst works in the same way as hunger, but can only be filled by drinking Plasma juice, eating Plasma fruit, or consuming Plasma from another Sim. Plasma is the Sim-equivalent of blood. In order to feed from a Sim, the vampire must ask permission and already have good relations with the Sim. When vampires drink from a Sim, they will bite in different places depending on the vampire's relationship with the Sim: on the wrist of a friend or on the neck of a lover. A desperate vampire can even go to the hospital or grocery store to raid Plasma, but they should watch out as they can get caught and arrested. Vegetarian vampires are limited to Plasma Fruit and Plasma juice. Meals cooked using Plasma fruit are edible by vegetarian vampires, but do not provide associated moodlets (except for Ambrosia). Feeding from a random Sim or eating a Plasma Fruit of at least very nice quality gives the vampire a +15 Moodlet, while feeding off of a Sim who is the vampire's hunt target or eating a perfect Plasma Fruit gives a +50 Moodlet. Vampires can also be fed at restaurants and will receive a positive "Sated" moodlet.
While a vampire's favorite food is always 'O-Positive', they are able to eat normal Sim food; however, it will not satisfy their Thirst motive. Like Hunger, drinking/eating while the motive is full will give the vampire the "Stuffed" moodlet and will cause weight gain if he/she continues drinking/eating with the moodlet.
Vampires cannot drink Plasma from children, ghosts, mummies, pregnant Sims, SimBots, Aliens, genies, or imaginary friends in their doll form.
Other MotivesAll other Motives function like they do for normal Sims. Vampires will receive a positive +15 "Night Vigor" moodlet after dark, but they still need to sleep. Unlike vampires in Nightlife, Late Night vampires do not sleep in coffins. Vampires can instead sleep on a specialized Vampire Altar or in normal beds. If the bed is of sufficient quality and the vampire receives a full night's sleep, vampires will also receive the positive "Slept Like the Dead" moodlet.
Interacting with Other Sims
Non-vampires can subconsciously detect vampires and their activities. All non-vampire Sims without the Brave, Daredevil or Evil trait near a vampire they do not know will receive a "Hunted" moodlet that takes away -10 Mood. If a Sim who is both a celebrity and a vampire bites someone in public, the Paparazzi will start a scandal about the bite, and the Vampire Celebrity will get the 'Publicly Disgraced' moodlet for the next 3 days. Vampires with the moodlet can go to City Hall and sue to have it removed (which is not always successful), or can pay off the Paparazzi for §3000. Public disgrace can be avoided if the Sim is invited into the vampire's home and is bitten there discreetly. Vampire celebrities will be publicly disgraced if they WooHoo with a mortal, either in public or on the home lot; Mortal Sims who WooHoo with vampires will become publicly disgraced for "WooHooing with an Occult."
Drinking from a Sim gives the Sim a positive +20 "Weakened" moodlet which lasts for 12 hours, during which the Sim cannot be drunk from again.
Adult vampires run in vampire speed when they play tag with children.
In Bridgeport, vampires are often found at Plasma 501, a vampire bar located in the center of the city. Sims may enter the bar only by bribing their way in, unless they have a celebrity status of at least 2. The Red Velvet Lounge is the supernatural hangout for vampires in The Sims 3: Supernatural. Vampires can be attracted to other towns by placing a lot and changing it to the "vampire lounge" lot type.
Interacting with pets
Cats and dogs can sense the difference between normal Sims and vampires. If there are any vampires on the lot, they will usually "Investigate the Strange Sim". The animal will display a thought bubble with an image of bats inside.
Becoming a Vampire
In the Sims 3: Supernatural, vampires can be created in Create a Household; however, in Late Night, Sims can only become vampires by befriending a preexisting vampire and then asking to be turned. If a Sim asks a vampire to bite them before they become friends, the vampire will refuse. The vampire will also refuse if there are more than 3 non-vampire Sims within a room. When a Sim is bitten after the interaction "Ask to Turn" or if the vampire "Offers to Turn" the Sim, the Sim will receive the "Unusual Blemish" moodlet for the next 3 days. During this time, unusual messages will pop up describing the transformation. At the end, the Sim will be engulfed in a spiraling cloud of red mist and bats, and perform the action "Complete Metamorphosis." 
Vampire ghosts can turn living Sims into vampires, but a ghost cannot be turned into a vampire.
The science lab provides an anti-vampirism potion for §3,000, which can cure a vampire of its condition. Additionally, the Potent Cure Elixir made with the Alchemy skill[TS3:SN] can also cure vampirism.
Unlike vampirism in Nightlife, vampirism in Late Night is genetic, and any children of a vampire (whether their parents are Vampire-Vampire or Sim-Vampire) will eventually have complete vampiric capabilities when they come into age.
These children are vampires from birth, as they appear under the relationships tab glowing red like a normal vampire would. Babies, toddlers, children, and teenagers cannot be cured by drinking the antidote until they are young adults. As toddlers, they will learn from their educational toys at a very fast rate, and get a small head start in learning Logic and Music (Depending on the level the toddler finished with his/her toy xylophone, as a teenager or older, when he/she plays an instrument, their skill on the instrument will be the same) but learn talking, walking, and potty training at the regular rate. When playing with their teddy bears or Imaginary Friend Dolls, they have the tendency to act like vampires and bite the necks of their toy. As toddlers, they can still eat normal food and take bottles and baby food.
As children, the only early sign of their vampirism is their ability to learn skills quickly. They can learn and master Logic, Writing, Fishing, Inventing, Photography and Painting, but as a child, they cannot master Cooking, Handiness, and Athletic. However, they can get a head start, similar to the toddler toys. They also eat normal food, as well as garlic, and can spend days outside. They can eat plasma-packs from the fridge, and plasma fruit at this age as well.
At their teenage state, they have the ability to learn all the skills. While all children of vampire heritage eventually turn into vampires, teens of two vampire parents will have a significantly higher learning rate than children of impure vampire ancestry. They still appear mortal and have the ability to go out. Teenager rules still apply to them and they are not allowed to break curfew at night. Also, they are old enough to use the special Vampire Altar bed.
They age at a normal rate until they transition into young adults. Then their appearance becomes that of a young adult vampire with the pale skin, glowing eyes, and all the maturity of a fully-grown vampire.
It is possible for a vampire and a ghost to have children. The child, however, may be a vampire, a ghost, or a mixed breed.
Special abilities of vampires include an extended lifespan. When vampires become young adults, their aging becomes abnormal. All young adult and adult vampires have a lifespan five times the length of a normal Sim's, although vampires are not immortal, unlike in The Sims 2. If they have mortal children before turning into vampires, it is possible the vampire can actually outlive their own children.
Other special abilities include the ability to "hunt." By clicking on a blank space of terrain on a lot populated by other Sims, the vampire will receive the option to hunt. Hunting gives a thermal aura around the victim  which reveals which Sim has the best plasma. This also gives them a tag in the map view, and an aura around the target's portrait in the Relationships tab. When a vampire has a target, they will get a wish to drink from that Sim. Drinking from the target not only refills the Thirst bar, but also grants a moodlet which prevents the Thirst bar from decaying until the moodlet expires.
Vampire Sims also have the option to make a Sim think of you. This causes the target Sim think of the vampire, which is usually indicated by a thought bubble over their head, and causes a relationship plus. This is greyed out for a certain amount of time after use.
Vampire Sims also have the ability to read minds. By doing so, the vampire Sim can learn a trait of target Sim, their career, star sign, relationship status, or favorites. This is also greyed out for a certain amount of time after use.
Vampire Sims will receive super speed and endurance, which means they can dash from one point to another in a matter of seconds. Vampires move at "Speed 5", in which a motion blur can be seen around the vampire. Super strength enables a Sim to work out for an infinite amount of time without getting fatigued. They can also break space rocks with ease but they still have to meet certain skill requirements. Vampires are unable to skate: they will run around skating rinks with vampire speed instead.
Vampires can learn skills faster, but only at night. If a vampire gets the Speedy Learner Lifetime reward, however, it does not make this accelerated skill gain any faster during night time, it only aids during the day. The learning rate increase also varies. Vampires who have just turned may learn almost at the same speed as a normal Sim, while unknown parameters can cause a vampire to master a skill in as short as under 3 hours; this may occur to a child of 2 vampire parents. The variation does not affect Cooking or Handiness skills. Skill books are not affected by this power and the progress is no faster than a normal Sim. However, being tutored in a skill or using a skill item like the guitar will result in accelerated learning.
In addition to faster skill gain at night, vampires can see in the dark and won't get the "It's Dark" moodlet. Furthermore, vampires visiting a graveyard at night won't receive the 'Creepy Graveyard' moodlet.
First and foremost, a vampire's weakness is thirst. If the vampire goes without Plasma for too long, they will receive the "Thirsty" moodlet. After the "Thirsty" moodlet comes the "Very Thirsty" moodlet, and finally the "Madly Thirsty" moodlet. If the "Madly Thirsty" moodlet ticks down to 0, a haunting chord will play in the background, the vampire will clutch at their throat, and eventually disintegrate into ash. The ghost will then appear black with a red pulsating light where the heart would be, and the Grim Reaper will appear as usual to collect them. The Sim will still be a vampire.
The other obvious vampire weakness is sunlight. Vampires can only go out in the sunlight for a short amount of time before getting the "Heating Up" moodlet, and they will start to smoke. The "Heating Up" moodlet lasts for 3 hours, then the vampire will pass out. After this, it changes to the "Too Much Sun" moodlet, and the vampire may not hunt, read minds, or override the emotions of other Sims. The vampire's thirst will also decrease at a much faster rate, forcing more plasma consumption until the "Too Much Sun" moodlet wears off or the vampire also has the "Sanguine Snack" moodlet. This moodlet will last two days and the timer will pause every time the vampire is outside during the day. The "Too Much Sun" moodlet can be removed prematurely by use of the Moodlet Manager or a spa package from a day spa. If the Seasons expansion pack is installed, vampires can also use a parasol to protect themselves from sunlight.
Garlic is another vampiric weakness. It can make the vampire sick. Eating garlic, food made with garlic, or drinks with garlic will give a vampire the "Garlic Breath" and "Nauseous" moodlet. It can cause them to pass out. It will also cause any vampire who romantically interacts with someone who's just eaten garlic to either get sick or pass out..
Vampires in The Sims 3: Supernatural
The Sims 3: Supernatural gives vampires several new abilities. Vampires are enhanced with hypnotic abilities and intimidation. They can become immortal and gain immunity to sunlight via a lifetime reward. Alchemy provides new ways to create and cure vampires, as well as temporary protection from sunlight. There are new interactions such as hypnotizing a Sim with "Hypnotic Gaze". Vampires can become immortal if they purchase the Immortal lifetime reward which prevents them from aging, meaning they cannot die from old age. The reward will grant them sparkles whenever they step into the sunlight, giving them full immunity to the sunlight. The sparkles will last until they go indoors or until night time. The sparkles will give a positive moodlet to appear for however long the vampire is in the sun.
Vampires now have a new Lifetime Wish exclusive to them called Turn the Town. They must drink from 20 different Sims and turn 5 Sims into vampires to fulfill this wish.
New Interactions for vampires are:
- Hypnotic Gaze
- Confess To Being a Vampire
- Deny Being a Vampire
- Accuse of Being a Vampire
- Warn Away
- Show Off Teeth
- Talk About the Joys of Plasma
- Compliment Dental Hygiene
- Enthuse About Garlic
- Demonstrate Bite Strength
- Complain About Vampires
When a vampire shows off their teeth to a non-vampire, the non-vampire Sim will develop a dislike to the vampire. Sims with the Supernatural Fan trait can "Compliment Dental Hygiene" (a reference to a vampire's fangs).
Vampires and vampire ghosts can use the Hypnotic Gaze on other Sims. Both the vampire and the victim's eyes will turn green, and the victim's skin will slowly turn white. However, the interaction can fail, resulting in the original vampire gaining the "Dazed" moodlet.
Other Life States
It is possible for a vampire sim to have another life state, thus making it a hybrid. However, only three are actual hybrids in the game, with the others being created by glitches. Like all sims vampires can become ghosts through death, with them appearing as a dark figure with a red pulsating light where their heart is. Zombie hybrids are also possible, and they walk like zombies despite resembling vampires, while spreading the normal zombie curse instead of vampirism. Finally, a vampire-witch hybrid is possible either through an elixir or genetics, and they can cast spells like witches while having vampire abilities.
The glitch created hybrids are: vampire-werewolf, vampire-mummy-sim, vampire-simbot, vampire-imaginary friend-ghost, vampire-genie, and vampire-imaginary friend. They are created through either genetics or elixirs, and generally retain the qualities of both species.
- This section is in need of additional information. You can help The Sims Wiki by expanding this section.
- Sims in transition from normal to vampire cannot become pregnant or travel overseas.
- If a vampire sleeps in the Cursed Sarcophagus of the Kings 3 times, it will replace one of the vampire's traits with the Evil trait.
- Using the "Cure" interaction of The Moodlet Manager (if successful) on a Sim who has begun the transformation to vampire will cause that Sim to instantly become a vampire.
- Vampires can also bite the Grim Reaper, though it won't turn him into a vampire. In fact, he won't even get the moodlet.
- While every vampire's favorite food is 'O-Positive', the lifetime reward, Change of Taste, can change this to another type of food temporarily. The game will eventually revert the favorite food back to O-Positive.
- Upon gaining the "Heating Up" moodlet, a vampire sim may receive a wish to enter into shade if any unpromised wish slots are open. If a wish slot is left open, the player can constantly gain lifetime happiness for that particular wish each time the moodlet is gained.
- In The Sims 2: Nightlife, vampires had no mirror image. In Late Night, vampires reflect normally in mirrors, though the vampires in The Sims 2: Nightlife are inspired by classic folklore, one of which is a story about vampires not being able to reflect onto mirrors.
- Most pre-made Vampires in Bridgeport have black hair with dark red highlights, although there are some exceptions.
- All Nightlife vampires (pre-made and player-made) have red eyes, while Late Night vampires can have any eye colour. However most pre-made vampires found in Bridgeport have red eyes (Moonlight Falls vampires tend to have non-red eyes, with the exception of Count Snypes).
- Most pre-made vampires tend to prefer Black over other colors. This alludes to their gothic preferences, though some exceptions exist, such as Morrigan Hemlock's favorite color (turquoise). Most also have the Evil trait (with William Fangmann and Wogan Hemlock being two pre-made exceptions) which reflects a pop culture stereotype of vampiric seduction and deception.
- Vampires cannot redeem coupons for clones or purchase the Clone Voucher lifetime reward as they are considered occults by the game.
- To make an instant vampire right after they have been bitten, go to Edit Town and split up the household, move the Sim that will be turned into a vampire in another household and switch households to the one you merged them with.
- Most Bridgeport vampires are enemies with another vampire. However, the only two vampires are enemies with a human and a ghost.
- Genies cannot be turned into vampires or drank from, as they lack plasma.
