    About

    Mobs Properties Randomness is a data-pack-driven mod for customizing mobs, applying randomized properties when they spawn and responding to events such as attacks, kills, target changes, ticks, and deaths. Data packs can give mobs potion effects, attribute modifiers, equipment, effect immunities, and NBT changes, with values and chances that can vary across a range. Event-based effects can target the mob or another entity, letting an attack apply effects to either participant, while presets make it possible to bundle properties into configurations such as a rare boss zombie. Rules can be shared across groups of mobs, such as zombies, skeletons, spiders, and creepers, and can be restricted by dimensions, biomes, or depth. Mob-specific settings include changing creeper fuse time and explosion radius, ghast fireball power, and phantom size. The mod also supports difficulty-sensitive values and equipment from other mods, including Tinkers' Construct items and materials. Mobs Properties Randomness provides the rules engine rather than ready-made changes, so its behavior depends on the data packs a user supplies; it runs server-side and allows vanilla clients to connect to a server using it.

    Written from Modrinth and CurseForge . How we write it

    In-game changes

    Changes the game's code in 1 area: Mobs and their behaviorChanges 3 game code files in this area: mobs, animals, villagers, projectiles and how they move and act..

    Adds no new blocks, items or other content.

    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.

    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 11 latest files checked, last on 15 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.
      11 latest files: the newest file for each Minecraft version and loader. The answer above is about the 3 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.
      Read without running it
    • 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 3 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 3 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

    AI was used for its code

    The author declares AI code on Modrinth.

    Claude Code is named in the files of its repository.

    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.
