You can turn a vampire Sim back into a human by using a "Turn into Human" potion. This potion is available in the "Vampire" category of the "Buy" mode in The Sims 4.
To use the potion, follow these steps:
- Purchase the "Turn into Human" potion from the "Buy" mode.
- Select the vampire Sim you want to turn into a human.
- Click on the Sim and choose the "Use Object" interaction.
- Select the "Turn into Human" potion.
- The Sim will drink the potion and transform back into a human.
Note: Turning a vampire Sim into a human will make them lose all their vampire powers and abilities. They will no longer be able to drink plasma, sleep in coffins, or use vampire powers.
Important considerations:
- The potion is a one-time use item.
- Once a vampire Sim is turned into a human, they cannot become a vampire again.
Remember, the "Turn into Human" potion is the only way to permanently revert a vampire Sim back into a human.
