Eidolon Data Recipes
If you have ever wanted to tweak the magical crafting systems in Eidolon without digging into Java code, Eidolon Data Recipes is the add-on you have been waiting for. This mod opens up the Crucible, Magic Worktable, and Spell recipes to data pack customization, letting modpack creators and tinkerers reshape how players interact with Eidolon's arcane progression. It is a small utility with a big impact on pack design.
What Eidolon Data Recipes Does
At its core, this mod provides the ability to supply custom recipes for Eidolon using data packs. Instead of hardcoding new recipes into a separate mod, you write JSON files that follow the same structure as Eidolon's built-in recipes. The mod then loads them at world creation or reload, making your changes available immediately.
The currently editable recipe types are:
- Crucible recipes – control what goes into the crucible and what comes out, including fluid and item outputs.
- Magic Worktable recipes – define new crafting arrangements and results for the worktable.
- Spell recipes – added in version 2.0, these let you create custom spells, though JEI support for spells is not yet available.
Custom rituals are planned for a future update, but the developer has clarified that they will not be entirely custom rituals. Instead, they will be tailored so you can, for example, spawn a custom mob or item using a ritual framework rather than building a ritual from scratch. That is a more realistic and stable approach for a data-driven system.
Supported Versions and Loaders
Eidolon Data Recipes was built for the Forge mod loader on Minecraft 1.16.5, matching the version of Eidolon it was designed to extend. It relies on data pack functionality, so you will need a mod like Open Loader to create and load data packs without leaving the game. This makes it compatible with most modpacks running Eidolon on 1.16.5 Forge.
It is important to note that this mod has been discontinued. The original developer is no longer working on it and will not port it to future Minecraft versions. An up-to-date continuation is being developed separately under the name Eidolon Data Recipes Complete, so if you are on a newer version, that is the project to follow.
How to Install Eidolon Data Recipes
Getting started is straightforward. First, make sure you have Minecraft 1.16.5 with Forge installed, along with the correct version of Eidolon and Open Loader. Place the Eidolon Data Recipes jar file into your mods folder alongside the other mods.
Once the game loads, you can create a data pack inside your world's datapacks folder. Follow the examples of built-in Eidolon recipes as a template, then adjust the JSON to match your desired inputs and outputs. Reload the data with the /reload command, and your custom recipes should appear in the appropriate Eidolon interface.
If you would rather skip the manual file management, the foxygame.net launcher offers a one-click install for Eidolon Data Recipes, dropping the jar straight into a pre-configured Forge profile so you can focus on writing recipes instead of sorting folders. The launcher's add-on catalog also tracks version compatibility, which is handy when you are juggling multiple 1.16.5 packs.
When you download Eidolon Data Recipes, keep in mind that the Ars Ecclesia guide book cannot display new or changed recipes due to how it was coded. If you are building a modpack, tell your players to use JEI for recipe lookup rather than relying on the in-game book.
Why Use It in Your Modpack
For pack developers, Eidolon Data Recipes for Minecraft is a lightweight way to integrate Eidolon into a themed progression without writing a companion mod. You can gate certain spells behind rare materials, rebalance crucible outputs, or create worktable recipes that tie into other mods' items. Because everything is data-driven, updates are as simple as editing a JSON file and running /reload.
The main limitations are the discontinued status and the lack of JEI support for spells. If you need spell recipe integration in JEI or support for Minecraft versions beyond 1.16.5, the Complete fork is the better choice. For everything else, this mod remains a practical tool for anyone serious about customizing Eidolon.
In short, Eidolon Data Recipes gives you control over Eidolon's crafting without the overhead of a full add-on. Install it, write your data packs, and reshape the mod's magic to fit your world.
