Instructions for Server Admins / Modpack Creators
If you are hosting a server or creating a modpack for friends, you can use this mod to help balance the server.
Configure settings on the client first:
Launch the game to the main menu, customize the spells as desired, and save your changes.
Copy the configuration file to the server:
Click the "Open Config Folder" button in the bottom-left corner of the GUI.
Copy the `irons_spellbooks_spell_config` folder.
Paste it into the `config/` folder of your dedicated server, overwriting the existing one.

Iron's Spells 'n Spellbooks natively reads individual JSON configuration files located at:

.minecraft/config/irons_spellbooks_spell_config/<namespace>/<spell_path>.json

Iron's Spell Tweaker GUI acts as a visual interface for this system:

1. Reads authentic defaults directly from each spell's DefaultConfig in memory.
2. Generates and saves standard Iron's Spells JSON config files formatted identically to manual configs.
3. Calls SpellRegistry.onConfigReload() upon saving or deleting configs, allowing real-time stat updates without restarting the game or server.
