    About

    Brutal Bosses adds challenging bosses to dungeons and other structures, placing them near loot containers. Its included roster contains more than 29 variants of vanilla entities, including zombie and wither skeleton bosses, a zoglin, witch, vindicator, vex, shulker, piglin brute, phantom, iron golem, and guardian. Each boss has custom abilities, stats, loot, and behavior, so encounters differ from one another. The mod works with structures that use lootable containers, including Awesome Dungeon, Dungeon Crawl, Dungeons Enhanced, When Dungeons Arise, YUNG's Better Dungeons, and YUNG's Better Strongholds; additional structures can be configured through datapacks. Datapacks also let players create and customize bosses based on nearly any entity, including entities from other mods.

    Security

    No harmful code found

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

    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 17 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.
      17 latest files: the newest file for each Minecraft version and loader. The answer above is about the 4 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
    • 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 4 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 4 files, for recent Minecraft versions. See each file in Releases

    AI

    No sign that AI was used to make it

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

    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.

    How we checked · 5 places read
