    • A pack of wild Book Wyrms

    About

    Book Wyrms adds colorful lizards to forests that turn unwanted enchanted books into new random enchanted books, giving players a way to recycle enchantments. The seven colors have different enchantment pools: gray wyrms can produce any enchantment, while red specialize in melee weapons, orange in ranged weapons, green in tools, blue in armor and shields, teal in fishing rods and tridents, and purple in certain modded items. Wyrms digest books over time, with their enchanting level determining how much magic is needed and the strength of the resulting enchantments, and their digestion speed determining how quickly they work; an Analyzer reveals these traits and their indigestion chance. Indigestion produces shredded-paper boluses and digestive fluids, which can be fed back to recover some of a book’s magic or made into Wyrmutagen to alter a wyrm’s stats or color; changing its color also makes it shed scales. Players can breed wyrms with plain books and raise them for meat and colorful scales, while their offspring can inherit different colors and traits. Modded enchantments can enter the appropriate pools, with examples including Ars Nouveau armor enchantments, Create’s Potato Cannon and Copper Backtank, and items such as Domestication Innovation’s Collar Tag and Alex’s Mobs’ Straddleboard. Several integrations add uses for wyrm materials: Farmer’s Delight supports slicing the meat and cooking stews, Mekanism, Create, Thermal Expansion, and Integrated Dynamics can grind scales into dye, and Botania can cycle scale colors.

    Written from Modrinth . How we write it

    In-game changes

    Does not change the game's code directly.

    Adds 38 items, 1 mob, 90 recipes, 8 loot tables and 7 sounds.

    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. 1 file in your config folder.

    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 15 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. 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.

    • Looked for, not foundWe looked for these in the file and did not find them.

    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 · 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
    • 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 that AI was used to make it

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