    About

    Multiplayer Boss Attribute Modifier scales boss attributes according to how many players are nearby, helping adapt boss fights to group size. When players approach or leave a fight, the mod updates configured stats such as health and attack damage; this is event-driven rather than based on constant polling. You can configure modifiers for individual boss types or tags in JSON, choosing the attributes and modification operation, setting per-player values, and capping how many players affect the scaling. The example configuration covers bosses tagged #forge:bosses, the Wither, and the Ender Dragon, with separate health and damage multipliers for the dragon. It works on dedicated servers and LAN, and does not require installation on clients.

    Security

    Not checked yet

    We have not checked its files for recent Minecraft versions yet.

    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 · Not checked yet
    • 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.
      3 latest files: the newest file for each Minecraft version and loader. All 3 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. 3 of them are not checked yet. See each file in Releases

    Privacy

    We have not read its code yet

    What it sends is not known yet.

    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 · Code not read yet
    • 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.
      None yet. See each file in Releases

    AI

    No sign so far that AI was used to make it

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

    We have not read its files, images, sounds and code history yet.

    AI in the game: not checked yet

    We have not read its code for AI yet.

    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.
