    About

    Celestial Core is a shared library for Celestial mods, providing common materials, potion effects, and attributes for them to use. It adds potions that increase the chance of a critical hit outside falling attacks, boost critical damage from both falling and other critical hits, or multiply healing.

    Written from CurseForge . How we write it

    In-game changes

    Changes the game's code in 3 areas, as a library other mods build on: Mobs and their behaviorChanges 4 game code files in this area: mobs, animals, villagers, projectiles and how they move and act., Rendering and graphicsChanges 2 game code files in this area: drawing mobs, items, particles and textures on screen. and Inventory and itemsChanges 1 game code file in this area: items, chests and other containers, crafting and enchanting..

    Libraries packed inside it change 8 more game code files: L2 Library, L2 Library, L2 Damage Tracker and 7 more.

    Adds 3 blocks, 60 items, 2 entities, 45 recipes and 3 loot tables.

    Counted from the names and data files in the mod, so the list may not be complete.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    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 · Both 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.
      2 latest files: the newest file for each Minecraft version and loader. Both 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.
      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 · Both 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 both 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
