    About

    Ars ’n Spells is a compatibility mod that connects Ars Nouveau with Iron’s Spells ’n Spellbooks, letting the two magic systems share resources, equipment bonuses, spell scaling, and progression rather than functioning as separate paths. Players can choose among five mana modes, from using one mod’s pool for both systems to sharing a bidirectional pool, splitting cross-mod spell costs between separate pools, or leaving the systems independent; conversion rates and related balancing options are configurable. Mana-related armor, enchantments, and Curio attributes can contribute across the systems, while Iron’s spell-power attributes can strengthen Ars spells and elemental bonuses can apply according to an Ars spell’s school. Casting spells from either mod can advance shared school progression, while affinity tracks the schools a player uses most; configurable resonance can also reward a nearly full mana pool, and nearby Ars Nouveau Source Jars can boost mana regeneration. A Spell Transcription ritual can place a spell from either system onto a compatible item, where right-click casts it and sneak-right-click cycles through multiple inscriptions; a matching uninscription ritual removes the stored spell data so the item can be reused. For a more direct Ars-to-Iron’s integration, the Spell Loom exports a custom Ars spell onto a real Iron’s scroll, which can then be bound into an Iron’s spellbook and cast from Iron’s native spell wheel alongside its original spells. Optional Covenant of the Seven integration adds casting with Life Points through the Ring of Seven Curses or Aura through the Ring of Seven Virtues, while themed Blasphemy curios can reduce spell costs for matching schools. Iron’s Spells ’n Spellbooks is optional: without it, the mod falls back to native Ars Nouveau behavior, while Ars Elemental and Too Many Glyphs are supported alongside optional integrations such as Blood Magic and Apotheosis or Apothic Curios.

    Security

    No harmful code found in the parts we could check

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

    2 of its files for recent versions cannot be checked: its author does not let other sites download them from CurseForge.

    What it can do on your computer

    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 mixinextras-neoforge, a library it includes. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 2 files 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 · 2 of 4 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.
      4 latest files: the newest file for each Minecraft version and loader. All 4 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. 2 of them are not checked yet. 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.
    • 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

    We found nothing it sends, in the 2 of its 4 files we read

    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 · 2 of 4 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 2 of 4 files, 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 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.
