    About

    Legendary Spellbooks is a compatibility addon that turns enemy abilities from Legendary Monsters into spells for Iron's Spells'n Spellbooks, allowing them to use that mod's existing magic system. Its spell collection spans Annihilation, Evocation, Blood, Lightning, Ice, Fire, and Nature, with abilities such as Annihilation Beam and Shockwave, Possessed Soul Blade, Hematite Trishula, Cloud Rail, Glacier Eruption, Flame Eater, and Ambush Thorns. Other additions include Flameborn Drift, Summon Flameborn Knights, Release Riftwalker Predator, and lightning spells such as Nimbus Array, Triple Nimbus Array, Tornado, and Quad Tornado. Possessed Soul Blade changes from the Evocation school to Blood after level 3, and Annihilation school damage also scales with ender and fire. The addon requires both Iron's Spells'n Spellbooks and Legendary Monsters.

    Written from CurseForge . How we write it

    In-game changes

    Changes the game's code in 2 areas: PlayerChanges 2 game code files in this area: your character: movement, abilities, hunger and controls. and Mobs and their behaviorChanges 1 game code file in this area: mobs, animals, villagers, projectiles and how they move and act..

    Adds 13 items, 4 mobs, 3 other entities, 7 recipes and 4 advancements.

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

    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 so far that AI was used to make it

    We looked for AI tools in its texts, files and images 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.

    How we checked · 4 places read
