The best Sims 4 trait mods give the Sims of The Sims 4 the personalities EA never shipped and the trait slots to hold them, led by More Traits in CAS, Chingyu’s 100 Base Game Traits Pack and Kuttoe’s New Emotional Traits. The 25 below run from extra slots and unlocked EA traits to big custom trait packs, infant and toddler traits, and single traits that each build one personality.
Each entry says which packs it needs, whether it runs on the base game alone, and where its creator stands on EA’s latest patch, and each links only to the creator’s own page. Four of them are also on our list of the 100 best Sims 4 mods, because no trait list is complete without them; the other 21 are new, so the two lists work together.
More Trait Slots and Unlocked EA Traits
Room for more traits, and the traits EA already made but keeps out of reach.
1. More Traits in CAS
The base game caps adults at three traits, and More Traits in CAS is the mod that lifts the cap: young adults and older get five, teens four, children three and toddlers two, while infants stay at one. Self-discovery from Growing Together still works on top of it, and you never have to fill every slot. In September 2026 thepancake1 stepped back from modding and handed the mod to Kallixer, whose post (756 likes) carries version 3a and marks it compatible with the October 27 patch (1.129.39); the original CurseForge page, with 1.7 million downloads, still has an older build. It edits the trait panel and the aging tuning, so any mod that changes those conflicts with it, including Chingyu’s More CAS Traits, and uninstalling it removes the extra traits from your Sims. Our traits guide covers every EA trait worth stacking. Creators: thepancake1 and MizoreYukii, now maintained by Kallixer. Needs: Base game only. Download: More Traits in CAS on Kallixer’s Patreon (a free public post).
2. Traits Remade in CAS
Many of EA’s best traits are locked away as reward or store traits. Chingyu’s Traits Remade in CAS (more than 652,000 downloads) remakes over 50 of them as traits you pick in Create a Sim, keeping only the ones with real gameplay effects, and gives each a Create a Sim animation, gameplay features and effects on character values and NPC reputation. They are for children and older, run on the base game with add-ons for a few packs, and leave EA’s own trait tuning untouched so they sit well with other mods. Chingyu made it as an alternative to ATICAS, which conflicted with some of Chingyu’s other mods. The newest file, version 1.4 (February 27, 2023), is tagged up to game version 1.113.291. Chingyu’s mod status spreadsheet marks it compatible with patch 1.117 (August 2025), the last patch the sheet covers, and as of November 2, 2026, it has no entry for any later patch. Creator: Chingyu. Needs: Base game only (the pack add-ons are optional). Download: Traits Remade in CAS on CurseForge.
3. Unhidden Traits and In Store
EA’s game files hold traits that never appear in Create a Sim or the Rewards Store. Unhidden Traits and In Store (220,000 downloads), built on SHUSHU’s older unhidden traits mod with more traits from the base game and newer packs, unhides them and puts them in the Rewards Store, where Sims buy them with satisfaction points. It edits EA’s trait tuning, the store needs XML Injector, and Chingyu warns that you should delete the files for packs you do not own, or the game may throw errors. Its page also names a handedness file to remove if you use KawaiiStacie’s Slice of Life from our big list, since both edit the same left- and right-handed traits. Version 2 (April 8, 2023, on CurseForge) is tagged up to game version 1.113.291, and Chingyu’s spreadsheet marks it compatible through patch 1.117 (August 2025), with no entry for any later patch as of November 2, 2026. Creator: Chingyu. Needs: XML Injector for the Rewards Store. Download: Unhidden Traits and In Store on CurseForge.
4. RBF Trait Buff Fixes
LittleMsSam’s Trait Buff Fixes, part of her RBF (Random Bug Fix) series, has 124,000 downloads and stops trait moodlets from landing on Sims who do not have the trait. It covers 28 buffs, such as Lovelorn for Romantic Sims, Need To Swipe for Kleptomaniacs, Afraid of the Dark, Missing Furry Friends for Animal Enthusiasts and Night Owl, so each now appears only when the Sim has the matching trait, and she asks players to report any other buggy trait buffs they find. It changes only EA’s own trait buffs. Its newest file is from March 5, 2026, and LittleMsSam’s site says all of her mods have been checked with the October 27 patch (1.129.39). Creator: LittleMsSam. Needs: No pack named on its page. Download: RBF Trait Buff Fixes on CurseForge.
Big Trait Packs
The downloads that add the most traits at once, most of them on the base game alone.
5. 100 Base Game Traits Pack
With 2.7 million downloads, Chingyu’s 100 Base Game Traits Pack is the most downloaded trait mod on CurseForge. It adds more than 100 traits that need only the base game, each with its own Create a Sim animation, autonomy, buffs and effects on emotions and relationships, from emotional responses to talents and weaknesses. A remade version 2, a free public post on Chingyu’s Patreon with nearly 1,600 likes, rebuilds 60 of the original traits from two of the five parts with more features, so remove Parts 1 and 4 of version 1 before you install it. Version 2 ships as Create a Sim traits and reward traits that can be used together, and the reward store needs XML Injector. The CurseForge file is version 1.7 (September 2023). Chingyu’s spreadsheet marks version 1 compatible through patch 1.117 (August 2025); for version 2, only an optional menu script broke on that patch, and Chingyu pulled it from the download. As of November 2, 2026, the sheet has no entry for any later patch. Creator: Chingyu. Needs: Base game only (XML Injector for the reward versions). Download: 100 Base Game Traits Pack on CurseForge.
6. New Emotional Traits
Kuttoe’s New Emotional Traits (nearly 1.5 million downloads) adds ten traits for children and older, five of them Extreme versions that push a mood much further: Arrogant (Self-Assured), Daydreamer (Creative), Egghead (Genius), Perky (Cheerful) and Stoic (Calm). The other five are Calm, Coward, Insecure, Oblivious and Restless, and every one comes with new moodlets, whims, social interactions and Character Values effects. An Egghead can become Fixated and earn a big boost to mental skills if you steer them to something productive in time, while a Coward is scared of many things, including the dark. It needs only the base game, and Kuttoe says this mod and all of Kuttoe’s others are free and will stay that way. The newest CurseForge file (September 20, 2025) is tagged for game version 1.118.242, its itch.io page was last updated on April 11, 2026, with a French translation, and as of November 2, 2026, Kuttoe has posted no status for the September 22 or October 27 patches. Our list of the best traits for storytelling pairs well with it. Creator: Kuttoe. Needs: Base game only. Download: New Emotional Traits on CurseForge.
7. Complete Traits Pack
klimter’s Complete Traits Pack (771,000 downloads) bundles the creator’s trait packs into one download. Its page counts 115 traits across More Social Traits, More Teen Traits, the Odd, Extreme and Planet-Inspired packs, More Hobby Traits, toddler, infant and elder traits, and stand-alone traits such as Hopeless Romantic, Possessive and People Pleaser. Each one changes some mix of autonomy, social interactions, moods, skill and relationship gain, career performance and needs. The traits sit in separate files inside the zip, so you can delete the ones you do not want, and the page warns not to install the individual packs alongside it. That includes More Teen Traits from our big list, which is already inside this bundle. It runs on the base game, with extra effects for Spa Day, Get to Work, Get Famous, Parenthood and Island Living owners. The newest file (October 22, 2026) came out before the October 27 patch, and as of November 2, 2026, its page has no status for that patch. Creator: klimter. Needs: Base game only. Download: Complete Traits Pack on CurseForge.
8. New Hobby Traits
From the creator of New Emotional Traits, New Hobby Traits (857,000 downloads) adds eight traits for what Sims love to do, each with moodlets, social interactions, holiday tradition preferences and whims. Artisans enjoy woodworking, flower arranging and baking but are bored by automated crafting; Competitive Sims swing hard on wins and losses; Horticulturists love harvesting; Movie Buffs get strong moodlets from films; and Scribes love writing books, blogs and journals. Technophobes are stressed by new technology and can accuse others of being robots, Tinkers learn Programming, Handiness, Rocket Science and Robotics faster and find activating a Servo as fulfilling as having a baby, and Worldly Sims need regular vacations or festivals. Most need only the base game, though Competitive uses Get Together and City Living assets and Movie Buff needs Movie Hangout Stuff. The newest file (September 20, 2025) is tagged for game version 1.118.242, and as of November 2, 2026, Kuttoe has posted no status for the September 22 or October 27 patches. Creator: Kuttoe. Needs: Base game (Movie Hangout Stuff for Movie Buff). Download: New Hobby Traits on CurseForge.
9. Absent Emotion Traits Pack
Absent Emotion Traits Pack (211,000 downloads) goes the other way from most trait mods: its 18 traits each stop a Sim from getting moodlets for one emotion, for Sims who simply never feel it. Each trait has a Create a Sim animation, whims and Character Values effects, and the pack comes in a Create a Sim version (in the Emotional category) and a reward version at 115 satisfaction points; the two can be used together, and the reward version needs XML Injector. Chingyu warns that any goal that needs a blocked emotion becomes impossible to complete. Version 1.4 (September 20, 2023) is tagged up to game version 1.113.291, and Chingyu’s spreadsheet marks it compatible through patch 1.117 (August 2025), with no entry for any later patch as of November 2, 2026. Creator: Chingyu. Needs: Base game only (XML Injector for the reward version). Download: Absent Emotion Traits Pack on CurseForge.
10. Misery Traits
NateTheL0ser’s Misery Traits, with nearly 198,000 downloads and more than 1,000 thanks on ModTheSims, adds the small everyday miseries the base game skips. Seasonal Affective Disorder brings occasional sadness in fall and winter, Hay Fever makes spring a sneezing season, Hates Heat and Can’t Stand Cold react to the weather until the air conditioning or heating kicks in, and Asthmatic Sims can have a two-hour uncomfortable spell set off by exercise, pollen, smoke or pet dander. There are also allergies to cats, dogs and magic, Chronic Headaches, Dry Skin, Fame Jealous, Alien Hater and Hates Vampires. Its page lists Get to Work, Cats and Dogs and Seasons, individual traits need others such as Get Famous, Realm of Magic, Eco Lifestyle or Vampires, and since version 5.1 the mod needs Lot 51 Core Library, so delete the old Misery Traits scripts before you update. One warning to take seriously: the creator reports that the account was compromised and asks anyone who downloaded the mod before 10:55 a.m. Central on March 1, 2026, to download it again; the current file was re-uploaded that day. The page names no game version. Creator: NateTheL0ser. Needs: Lot 51 Core Library, plus the packs for each trait. Download: Misery Traits on ModTheSims.
11. Illness Traits Bundle
BosseladyTV’s Illness Traits Bundle (168,000 downloads) covers two health traits for children through elders. Chronically Ill Sims are often tired, get headaches and need more rest than others, and Immunocompromised Sims catch illnesses more easily, show symptoms more often and may avoid crowded places. Ill Sims can book a doctor visit at the clinic from their phone and come home with medicine for temporary relief, and the bundle includes the Doctors Cure Ailments mod, so that is not a separate download. It was updated for Enchanted by Nature, where these Sims are also more likely to become imbalanced if that system is on. It needs XML Injector, plus Get to Work or Enchanted by Nature for Sims to get sick at all. The newest file (July 25, 2025) is tagged for game version 1.116.232, and as of November 2, 2026, its page has no status for the September 22 or October 27 patches. Creator: BosseladyTV. Needs: XML Injector, plus Get to Work or Enchanted by Nature. Download: Illness Traits Bundle on CurseForge.
12. New Spa Day Traits
Kuttoe’s third trait pack, New Spa Day Traits (168,000 downloads), adds two lifestyle traits built around Spa Day. Health Nuts get strong moodlets from yoga, enjoy cardio, saunas and tea, gain Wellness faster and lose Energy a little more slowly. Lavish Sims hate chores like cooking, cleaning, gardening and repairs but perk up when pampered with baths, hot tubs and massages; they struggle in the Military, Manual Labor and Fast Food careers, excel as Critics, and get more stressed the smaller a Tiny Home gets. Both come with moodlets, socials, holiday tradition preferences and whims. The newest file (August 21, 2025) is listed for game version 1.117.227, and as of November 2, 2026, Kuttoe has posted no status for the September 22 or October 27 patches. Creator: Kuttoe. Needs: Spa Day. Download: New Spa Day Traits on CurseForge.
13. Allergic to Fur and More Traits
ilkavelle’s Allergic to Fur and More Traits (90,000 downloads) gives pet households something to work around, with nine traits in three sets. Allergic to Fur, Cats or Dogs makes a Sim sneeze and cough near animals, with allergy pills to buy on the computer and a three-dose immunotherapy course, booked from the phone, that cures it for good. Hates Animals, Cats or Dogs brings an angry moodlet near them, slows relationships with pets to a fifth of the normal speed and adds mean interactions, while Afraid of Animals, Dogs or Cats makes a Sim tense, halves relationship gain and leaves only the cautious introduction, with a therapy session that eases it for a while. An optional add-on lets Sims buy the traits. The Hates and Afraid traits conflict with Cat Lover, Dog Lover and Animal Attraction. The newest file (February 28, 2026) is tagged for game version 1.126.78, and ilkavelle’s October 27 patch post says all of her mods are compatible with that patch. Creator: ilkavelle. Needs: Cats and Dogs. Download: Allergic to Fur and More Traits on CurseForge.
Infants, Toddlers and Kids
The youngest Sims get a single trait each in the base game, so these make that one count.
14. Snuggly (Infant Trait)
Artemissy has 32 trait mods on CurseForge with more than 7 million downloads between them, and Snuggly (638,000 downloads) is the most downloaded. Snuggly infants thrive on close contact: they love being held, cuddled and comforted, are happiest around the people they love, need more attention and social interaction than other babies, and unlock their social milestones a little faster. With Growing Together, version 2 also gives them extra quirks. Our guide to changing a Sim’s traits covers swapping it later. The newest file, version 2.3 (January 28, 2026), is tagged for game version 1.121.361, and as of November 2, 2026, its page has no status for the September 22 or October 27 patches. Creator: Artemissy. Needs: No pack named on its page (Growing Together for the quirks). Download: Snuggly on CurseForge.
15. Spoiled (Toddler Trait)
Artemissy’s Spoiled toddlers (510,000 downloads) are, in the page’s words, not fans of sharing. They pick up Thinking 1.5 times as fast but Communication at 0.8 times the speed, and their Fun need drains 1.5 times faster, so they need constant entertaining; version 2 adds quirks for Growing Together owners. The newest file, version 2 (January 31, 2026), is tagged for game version 1.121.361, and as of November 2, 2026, its page has no status for the September 22 or October 27 patches. Creator: Artemissy. Needs: No pack named on its page (Growing Together for the quirks). Download: Spoiled on CurseForge.
16. Childhood Consequences
tyjokr, the creator of Deeper Social Autonomy on our big list, made Childhood Consequences (90,000 downloads) as the flip side of EA’s Gifted traits. A played child who ages up to teen without reaching level 4 in a childhood skill gains a matching negative trait for life: Boneheaded slows mental skills, Tongue-Tied social skills, Unimaginative creative skills and Uncoordinated physical skills, each at 0.75 times the normal speed where Gifted Sims learn at 1.25. You get a notification when a child reaches level 4 and is safe, and children you do not play have a small chance of a trait based on their other traits. It needs Lot 51 Core Library and overrides no game files. The newest file (April 9, 2026) is tagged for game version 1.126.58, and tyjokr has listed the project on CurseForge for game version 1.129.39, the October 27 patch. Creator: tyjokr. Needs: Lot 51 Core Library. Download: Childhood Consequences on CurseForge.
Personality Traits
Single traits that each build one kind of Sim, most with their own interactions and whims.
17. Sassy
Artemissy’s Sassy (395,000 downloads) is a social trait for bold, witty Sims. They learn Charisma 1.5 times as fast, Acting 1.3 times and Research and Debate 1.2 times, but Handiness at 0.8, and children build their Social skill 1.5 times as fast. Their Social need drains 1.5 times faster and their Hygiene more slowly, and their friendships grow 1.2 times as fast. The newest file, version 1.2 (July 6, 2024), is tagged for game version 1.107.112, and as of November 2, 2026, its page has no status for any patch since. Creator: Artemissy. Needs: No pack named on its page. Download: Sassy on CurseForge.
18. Sensitive
Sensitive (387,000 downloads) is Artemissy’s emotional trait for Sims who are deeply in tune with their own feelings and everyone else’s: they get upset more easily but show strong empathy. They learn Parenting and Writing 1.2 times as fast, and their Empathy grows 1.5 times faster while their Emotional Control grows at 0.6. Version 2 (March 3, 2026) rewrote it to match EA’s traits more closely and is tagged for game version 1.121.372; as of November 2, 2026, its page has no status for the September 22 or October 27 patches. Creator: Artemissy. Needs: No pack named on its page. Download: Sensitive on CurseForge.
19. Gold Digger Trait
The Gold Digger Trait (375,000 downloads) makes money the point of a Sim’s life. Gold Diggers are driven to pile up wealth and possessions and will go to great lengths to get them, with new whims, moodlets and interactions built around materialism and shopping sprees. Our guide to making money fast gives them a head start. Version 2.2 (March 19, 2025) is tagged for game version 1.113.291, and as of November 2, 2026, its page has no status for any later patch. Creator: m0therx0fxcha0s. Needs: Get to Work and XML Injector. Download: Gold Digger Trait on CurseForge.
20. Girly Girl Trait
KiaraSims4Mods makes dozens of single-trait mods, and Girly Girl (248,000 downloads) is one of the most downloaded. Girly Girl Sims, teen and older, get happy moodlets from massages, trying on outfits, scented baths, manicures, pedicures, face masks and primping in the mirror, and from recording beauty and fashion videos, and they can chat about chick flicks, make-up, outfits and hairstyles. It conflicts with Kiara’s Tomboy trait (No. 23). Kiara’s mod status sheet, which lists the October 27 patch (1.129.39) as the latest, marks it compatible. Creator: KiaraSims4Mods. Needs: Get Famous, High School Years, Spa Day and XML Injector. Download: Girly Girl Trait on CurseForge.
21. House Spouse Trait
House Spouse (232,000 downloads) is Kiara’s trait for young adults and older who run the home while their partner works. They learn Baking, Cooking, Gourmet Cooking and Parenting 1.5 times as fast, get happy moodlets from cooking, baking, cleaning, helping with homework and playing with the kids, can chat about family values, and roll whims around meals and parenting. It conflicts with Hates Children, Lazy, Noncommittal and Unfaithful. Kiara’s status sheet marks it compatible with the October 27 patch. Creator: KiaraSims4Mods. Needs: Get to Work, Growing Together, Kids Room Stuff, Lovestruck, Parenthood, Seasons and XML Injector. Download: House Spouse Trait on CurseForge.
22. Queen Trait
Queen (196,000 downloads) is Kiara’s trait for the Sim at the head of a royal family. Queens enjoy giving speeches, making charity donations, drinking tea, baths and massages, replying to noble mail and donating to a kingdom, roll whims around charity, parties, clubs and keeping the butler in line, and nearby Sims bow and get a moodlet when a Queen is around. Kiara’s King Trait, a separate download, is its counterpart, and the two conflict. It needs more packs than any other entry here, so check the list below before you download. Our guide to becoming a noble covers the Royalty and Legacy side. Kiara’s status sheet marks it compatible with the October 27 patch. Creator: KiaraSims4Mods. Needs: City Living, Get Famous, Get Together, Fitness Stuff, Eco Lifestyle, Parenthood, Royalty and Legacy, Spa Day, Vintage Glamour and XML Injector. Download: Queen Trait on CurseForge.
23. Tomboy Trait
Tomboy (184,000 downloads) is the sporty counterpart to Girly Girl, for Sims, teen and older, who would rather play sports, video games, darts, foosball, chess or cards and watch sports on TV. They can chat about sports and roll whims for basketball hoops, dunk challenges and giving a friend a “bro gift.” It conflicts with Girly Girl, so pick one per Sim. Kiara’s status sheet marks it compatible with the October 27 patch. Creator: KiaraSims4Mods. Needs: City Living, Get Together, Lovestruck, Seasons and XML Injector. Download: Tomboy Trait on CurseForge.
24. Needy Trait
plumlace’s Needy trait (157,000 downloads) gives a Sim a constant need for attention and reassurance, so their mood swings between highs and lows. It adds four interactions: Beg for Attention, Ask for Reassurance, Set Unrealistic Expectations (lavish gifts, big outings or grand romantic gestures) and Discuss Fear of Abandonment, which gives loved ones a chance to comfort them. Version 1.6.1 (May 29, 2024) is tagged for game version 1.107.112, and as of November 2, 2026, its page has no status for any patch since; plumlace handles support on Discord rather than on CurseForge. Creator: plumlace. Needs: No pack named on its page. Download: Needy Trait on CurseForge.
25. Dale Deaf Trait
DaleRune’s Deaf trait (113,000 downloads and 383 thanks on ModTheSims) represents deaf and hard of hearing Sims. Since version 2.0 the trait itself costs nothing in the Rewards Store, and each deaf Sim can then buy one accommodation as a reward trait: Lip Reading, SSL, Hearing Aids or Cochlear Implants. Deafness halves the learning speed of instrument skills, DJ Mixing, Singing, Media Production and Child Social and the Entertainer career’s performance, which rises to 0.8 with hearing aids or implants, and it turns off music likes and dislikes except with hearing aids. The page lists known gaps, including hearing aid batteries that do not work and an accommodation choice that sometimes has to be made twice. It is base game compatible and has a separate version for Lumpinou’s Mood Pack (download only one). The last update was on October 9, 2021, and the page names no game version. Creator: DaleRune. Needs: XML Injector, for everything to work. Download: Dale Deaf Trait on ModTheSims.
Setting Up Trait Mods
Several of these are script mods, so turn on both Enable Custom Content and Mods and Script Mods Allowed in the game’s options before you add them. Our guide to installing Sims 4 mods and custom content walks through the folder setup.
Two library mods come up in the Needs lines: XML Injector (see our XML Injector guide), which every reward-store version and most of Kiara’s traits need, and Lot 51 Core Library, which Misery Traits and Childhood Consequences need. Each is a free, separate download, and you only need one copy however many mods use it.
Custom traits compete for the same slots as EA’s, so install More Traits in CAS first if you want Sims with more than three. Reward versions do not appear in Create a Sim: Sims buy them in the Rewards Store with satisfaction points, or you can add them with a cheat mod such as Smart Sim Cheats from our big list.
Watch for the conflicts the creators list. Girly Girl and Tomboy cannot share a Sim, and neither can Queen and King; ilkavelle’s Hates and Afraid traits clash with Cat Lover, Dog Lover and Animal Attraction; klimter’s single packs duplicate Complete Traits Pack; and version 2 of the 100 Base Game Traits Pack replaces Parts 1 and 4 of version 1. More Traits in CAS conflicts with Chingyu’s More CAS Traits, so use one or the other.
Script mods and trait tuning often break when EA patches the game, so after every update, check each creator’s page before you load a save. Our guides to fixing mods after a game update and clearing the cache cover the cleanup.
How We Chose These Mods
Every mod here adds traits to Sims, unlocks EA’s own hidden traits or gives Sims room for more. Lot traits, which change lots rather than Sims, are left out, and so is Create a Sim custom content. We ranked by each platform’s own popularity data for this theme: total downloads in CurseForge’s Sims 4 section, searched for “trait” and “traits” and sorted by total downloads; likes on the creators’ free public Patreon posts; and downloads and thanks on ModTheSims for the two mods that live there. Every entry was checked on its creator’s own page for three things: that the download is free and public, that it is still there, and what the creator says about the latest patch. We left out adult or adult-themed traits and anything that needs an adult framework, paid or early-access-only releases and near-duplicates (klimter’s separate packs, which are all inside Complete Traits Pack), and we capped any one creator at four entries. Four of the 25 are also on our big Sims 4 list: More Traits in CAS, the 100 Base Game Traits Pack, New Emotional Traits and New Hobby Traits. For everything else in the game, see our Sims guides hub.
Frequently Asked Questions
What is the best trait mod for The Sims 4? By downloads, Chingyu’s 100 Base Game Traits Pack, with 2.7 million on CurseForge, followed by More Traits in CAS and Kuttoe’s New Emotional Traits. For the most traits in one download that is still being updated, klimter’s Complete Traits Pack is the pick.
How do you get more than three traits in The Sims 4? Install More Traits in CAS. It gives young adults and older five trait slots, teens four, children three and toddlers two. Without a mod, extra traits come only from rewards and gameplay, which our traits guide covers.
Do Sims 4 trait mods need any packs? Most of the big packs here run on the base game alone. The exceptions are Kiara’s traits, which need several packs each (Queen needs nine), New Spa Day Traits (Spa Day), Gold Digger (Get to Work), Allergic to Fur and More Traits (Cats and Dogs), and most of the Misery Traits. If you are deciding which packs to buy, our ranking of the best Sims 4 expansion packs can help.
Why don’t my custom traits show up in Create a Sim? Check three things. Reward versions only appear in the Rewards Store, and they need XML Injector to show up there at all. If your Sim’s slots are full, the new traits are there but there is no room to pick them. And if a patch just came out, the mod may need an update, so check the creator’s page.
Are there trait mods for vampires, spellcasters and other occults? Yes, and they have their own list: our best Sims 4 occult mods cover vampires, spellcasters, werewolves, mermaids and brand-new occults.
Do Sims 4 trait mods work on console? No. Gameplay mods like these are for the PC and Mac versions of The Sims 4 only.
