    About

    Slime Overhaul adds four elemental slimes to the world: air, water, earth, and fire, each with its own behavior and habitat. Air slimes appear on mountain tops and at high altitudes, jump higher than ordinary slimes, and can double-jump; water slimes inhabit rivers and oceans, swim and breathe underwater, and can attack fire slimes. Earth slimes spawn in plains and forests, move more slowly, have more health, and do not float in water, while fire slimes are usually found in the Nether, are immune to fire, take damage from water, and can attack water slimes. The mod also adds six potions, including effects for a midair jump, resisting knockback, and being pushed out of water or lava, plus recipes that extend fire resistance and water breathing potion durations using the corresponding slime blocks. Slime blocks can be made to glow with glow ink, and an earth slime ball can be used on an anvil to upgrade a shield so it reflects damage when blocking attacks, including on shields from other mods. Other additions include five banner patterns, four blocks, two mechanics, and six achievements, with five achievements listed for one supported version.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for NeoForge 1.20.1 to 26.1.2.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 5 latest files checked, last on 16 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      5 latest files: the newest file for each Minecraft version and loader. All 5 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.

    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Looked for, not foundWe looked for these in the file and did not find them.
      The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · All 5 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of all 5 files, for recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its texts, files and images and found none.

    We have not read its code history yet.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
