To become a vampire in The Sims 3, befriend an existing vampire and use the Ask to Turn interaction; if they accept, they bite your Sim, and after about two days of strange symptoms the transformation completes. Vampires come with the Late Night expansion, and Supernatural expands them further. Here is the full process.
Step-by-Step: Getting Turned
- Find a vampire. With Late Night, vampires haunt Bridgeport’s clubs and bars after dark; look for the pale skin, glowing eyes, and dramatic entrances. In Supernatural’s Moonlight Falls they are ordinary neighbors.
- Build the relationship. Ask to Turn is not offered to strangers; a solid friendship (or romance) is required, and success rises with the relationship.
- Use “Ask to Turn.” If they agree, they bite your Sim, who gains the Unusual Blemish moodlet.
- Wait roughly two days. Your Sim itches, gets strange messages, then “Completes Metamorphosis” and wakes up a vampire.
Late Night vs Supernatural Vampires
Both packs’ vampires coexist in one system, but Supernatural adds quality of life:
- Create a vampire directly in Create a Household with Supernatural (Late Night alone has no CAS vampire option).
- Vampiric Sunscreen elixir grants sunlight immunity, fixing the classic daytime problem.
- Extra socials like Hypnotic Gaze, Intimidate, and Show Off Teeth, plus the Turn the Town lifetime wish.
With only Late Night, expect classic limitations: sunlight weakness and plasma cravings managed through plasma juice and willing donors.
Want Out? The Cure
We keep the full reversal process in its own guide: how to cure vampirism in Sims 3. The short version involves science and a fee, so becoming mortal again is easier than becoming immortal.
Tips Most Players Miss
- Vampires level skills faster at night. Lean into the nocturnal schedule instead of fighting it.
- Plasma juice removes the hunt. Stock the fridge and your vampire never needs to stalk anyone.
- Mixing occults is possible in Sims 3, unlike Sims 4, but combinations get strange; our other occult guides cover werewolves, witches, fairies, and mermaids.
Frequently Asked Questions
How long does the transformation take after the bite? About two in-game days from bite to metamorphosis, give or take a few hours.
Can vampires age and die? Sims 3 vampires age extremely slowly and live roughly five times longer than mortals, but they are not truly immortal.
Can a vampire turn my whole household? Yes, one turned Sim can eventually spread it, though each turning needs relationship and consent via the same flow.
Do I need both Late Night and Supernatural? No; either pack provides vampires. Supernatural alone offers the most complete version, including CAS creation.
