Haunted house residential

Haunted house residential is a lot assignment introduced in The Sims 4: Paranormal Stuff. It is a regular residential lot that includes various "spooky" occurances that only happen at night. Small ghosts known as Specters are seen roaming around the lot, which Sims can interact with. Other events such as flickering lights, pipes rattling or creepy dolls are also regularly found on this lot type.

Spiritual Volatility
Haunted houses have a status of spiritual volatility which dictate how much paranormal activity, haunted items, and ghostly presence appears during the night. Mediums can use a seance table to sense the spiritual volatility and even help calm it down by interacting with the specters and performing ceremonies. Sims who don't get rid of haunted objects will start to experience more paranormal activity as well as the specters start becoming angry.

Guidry the Ghost
Claude René Duplantier Guidry is an NPC that appears after a day or two after a Sim has moved into a haunted house, and he will offer questions and help teach Sims the basics of how to interact with specters and other paranormal happenings as the days go by. When Sims achieved maximum medium skill, they can talk to Guidry about the paranormal investigator liscence so the Sim can have the option in the career Freelancer.

Bonehilda
Bonehilda is another NPC that is capable of being summoned after a few levels in the medium skill. Other than operating as a maid as well as a home friend, Bonehilda is capable of fending off evil specters for Sims.

Temperance
Temperance is a ghost NPC who will appear quite a while after the Sim has moved into the haunted house and she will try to make sure that Sims have a hard time trying to appease the ghosts so that the spiritual volatility will get worse and thus more spooky and scary events start to happen.

Cursed Objects
Living within a haunted house, Sims will notice overtime there will be strange objects appearing throughout the lot. The range of cursed objects are a creepy doll, a sculpture of hands, creepy branches, ectoplasm puddles, etc. When encountering these objects Sims will get the scared emotion and thus makes trying to destroy them hard. Cursed objects collectively bring down the spiritual volatility faster. If Cats & Dogs is installed, pets will react negatively to cursed objects.

Benefits of Haunted House
Sims might wonder why one would move into a house that is haunted. But few know of the benefits when you're on good terms with the ghosts.

Sims can recieve a couple benefits from being friendly with their specters, specters can leave behind spooky candy and ecto cupcakes every now and then, as well as the added bonus of specters being able to protect your home from unwanted visitors such as vampires like Vladislaus Straud or even the Welcome Wagon.

Heroic Mode
There is a hand decor item from the build mode catelog that allows players to stop Guidry from appearing, but more usefully is able to enact "Heroic Mode" which is a challenge mode where spiritual volatility decays faster and earn more satisfaction points. This mode makes Sims experience a more challenging side of living within a haunted house, it will be beneficial to get the Brave trait from the rewards store to help go through this challenge easier.

Once heroic mode has been activated, it cannot be stopped until after 24 Sim hours from when it was activated.
