Overview

You want me to introduce them? Alright. Ahem--

Reactive Alchemy (or Reactive for short) is an alchemy-themed magic mod centered around in-world experimentation. It features:

A fully-fledged system of elemental Powers that react with each other automatically
Numerous arcane tricks and techniques to create useful effects and items
Many features that behave slightly differently in every new world
A system of custom-made and custom-nameable blocks that you can create and discover
The promise of teleportation, automatic block breaking, magical weaponry, and turning copper into gold
A charismatic and well-written guide book that leads you to discover the mechanics at your own pace
Strange materials still waiting to be discovered
What remains of our voice

Here's the trailer for version 10:

Getting Started

The Journal of Alchemy can be crafted with a book, a stick, and a bottle, and can serve as your guide through the rest of the mod. Each page is written in the style of alchemist's notes from one of three different narrators. Some of the mod's content is described in the form of "Objects of Study", which require you to run some kind of experiment before their secrets are revealed, but essential mechanics are outright explained.

Naturally, JEI integration for all items is present.

If you prefer a more direct reference, see the wiki.

Configuration

The mod is largely data-driven, so any of these features can be added or changed using a datapack:

Sources of Power
Power Release recipes
Transmutation recipes

More may be added on request! For information about the recipe format, see the readme on the github page.

There are also options in the config files to change certain performance settings, elucidate one of the mechanics, and set the seed for world-specific mechanics.

Compatibility

Using KubeJS and/or Json Things, pack developers can add new Reactions and even new kinds of Power.

The mod has special interactions with Create (the Display Link can read Crucible information) and (on 1.20.1) Pehkui.

Additionally, the mod features built-in compatibility for the following mods, in the form of accepting some of their materials as Power sources. More will be added at request, and remember you can add more with a datapack if needed.

Quark
Botania
Oh The Biomes You'll Go
Mana and Artifice
Ars Nouveau
MagiChem
Malum
Wizards Reborn
Occultism

Usage

This mod is under the CC-BY-NC-4.0 license, and you are allowed to use it in any modpack you like. I'd love if you let me know that you're using it, but that's by no means a requirement.

Support

If you encounter a bug or have a suggestion, please send it to the issues page! I'm making this as a side project, so updates and ports will occur only when I have time.
