Sims 4 Vampire in CAS

@Sabriajin, the only way I know of making a Vampire Sim to not be a Vampire anymore is in the game ...  Once their Vampire Lore level is high enough by reading the Vampire encyclopedias they will get the knowledge to make a drink at the bar to cure their Vampirism.  (You also have to have the right ingredients on hand like Wolfsbane, etc.)  There might be a way of doing it in CAS, like a certain cheat, but I don't know how to do that.  their also might be a Mod you can download and use, but Mods often cause problems with game updates.  Best of luck, and tell us if you fix your problem or not!  🙂

@Sabriajin , I'm glad you found an easier way to get rid of their Vampirism than what I suggested! 🙂  Thanks for sharing with us, as I'm sure this will help others! ❤️

Is it just me or does anyone else thing its REALLY silly that you cant undo that before you save the sim?   I too made a vampire sim then changed my mind, but spend a lot of time making her and I really like how she looks.  How is this not reversible? I get it if i saved and went back in, but when you are creating a sim you have full editing choices.  Not to mention if you want to make a vampire or an alien, there is no way to do so with the sim they give you when you open CAS.  If you have full cas edit choices and click on the image of the sim in the lower left corner, the options should come up just like they do when you click the add a sim button.

I found out that In CAS YOU CAN DELETE THEIR DARK FORM ENTIRELY. The have a human throw the potion in your face or just drink it. I actually made the stepford cuckoos and have them a mind control but less vampire like. But that’s the easiest way I know of doing it. I mean not sure if it takes away being a vampire or if you just have a dark form. I’m too nervous to try. Let me know if you have!

Super Easy and quick way to do this

Making sure you've done Testingcheats true 

Then do the cheat to show all hidden objects bb.showhiddenobjects

then search for vampire cure and then select any of the two drinks that show up and buy them. Then you just have that sim drink the drink and boom. Super easy and doesn't require any Vampire Lore skill. 🙂

I know this was posted 3 years ago, but If anyone is still having troubles, this is how I did it.
First, press SHIFT ctrl c
Second, type in testingcheats true
Third, Type in bb.showhiddenobjects
Finally, type in "stats.set_skill_level VampireLore 15" without the " and go into build mode, search up Wolfsbane, Garlic, and Plasma Fruit. Get 10 of each. Buy/go to a bar and make The Ultimate Vampire Cure. They cost 2,500 each so type in "Rosebud" without the " 3 times to get enough money for one. Then drink it! Boom! Non vampire!
