If you’re looking for an ancient, magical mermaid set, the Arcane Illusions collection is a stunning choice. The top and tail share the same mystical design language: soft gradients, glowing metallic details, and delicate embellishments. The tail comes in 44 swatches, while the matching top has 41. This gives you endless combinations for storytelling or CAS screenshots. This outfit is perfect for moon-born mermaids, ocean priestesses, or supernatural sirens. You’ll need the Island Living EP for the tail.
Follow these steps to install Arcane Illusions Mermaid Lunae on your Sims 4 game:
Download the mod file from the link above. Sims 4 mods typically come as .package or .ts4script files.
Open your Sims 4 Mods folder. The default location is: Documents/Electronic Arts/The Sims 4/Mods
Place the downloaded file directly into the Mods folder. You can organize mods into subfolders up to one level deep.
Launch The Sims 4 and go to Game Options > Other. Make sure "Enable Custom Content and Mods" is checked.
Restart the game if it was already running. The mod should now appear in your game.
Important: Always back up your save files before installing new mods. After Sims 4 updates, mods may need to be re-downloaded or updated by the creator.
Platform
The Sims 4 (PC/Mac)
Pro tip: If a mod stops working after a game update, check the creator's page for an updated version. Broken mods can cause the game to behave unexpectedly.
