What is ZanderCore?
ZanderCore is the core library behind the Zander's Mods ecosystem. It provides the shared crafting systems, Recipe Book, configuration tools and server synchronization used by my Reinforced mods.

- Compatible Zander mods automatically add their own recipes, pages and systems
Features

- Vanilla Mode for Armors, Tools and Swords
- Enable or disable mechanics such as Blessings, Gems, Hearts, Forges and Passives

- JEI, Creative Tabs, tooltips and Recipe Book pages automatically adapt to disabled content
- Full server-side configuration and synchronization
Server Configuration
On multiplayer servers, the server controls all gameplay settings.
- Players can view the configuration, but cannot change server settings
- OP / administrators can configure ZanderCore directly from the in-game Zander's Mods menu
- Settings can also be changed through server commands
- Changes are synchronized automatically with all connected players
Required by all mods in the Reinforced ecosystem.
