    About

    Arcanus is a magic mod focused on letting players craft their own spells and cast them through a staff-based system. Players begin their magical journey by finding a Wizard Tower, wearing a wizard hat, and speaking with the wizard at its top; knowledge scrolls from the wizard unlock spell shapes and effects for crafting. To build a spell, place a spell book on a lectern and chain shapes, which determine how effects reach a target, with effects such as damage or freezing; a self shape affects the caster, while a projectile shape applies effects to what it hits. Spells are selected and cast using combinations of mouse inputs mapped to eight staff slots, and their square and circle symbols appear around the caster's crosshair and in front of other players. Spell power is limited by mana cost, and the mod includes an in-game Compendium Arcanus and configuration options for disabling individual spell shapes or effects.

    Security

    No harmful code found

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

    What it can do on your computer

    Uses your Minecraft account login
    It can use the login of your Minecraft account, for example to join a server. Found in DataSync-Minecraft, a library it includes.Not a Warning: we read its code and found no login token sent anywhere but Mojang.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Found in DataSync-Minecraft, a library it includes. See Privacy

    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 3 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.
      3 latest files: the newest file for each Minecraft version and loader. The answer above is about the one for a recent version. 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.
    • Uses your Minecraft account login
      Uses your account login to join a server.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    Uses your Minecraft login

    We read its code without running it: your login goes only to Mojang's own login service, as in the game itself.

    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 · Its one file 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 its one file, for recent Minecraft versions. See each file in Releases
    • sessionserver.mojang.com
      Talks to the Minecraft login service.From a bundled library.
      Login check with Mojang
    • 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, images and sounds 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.
