RuneCore is a modular magic system designed for future Hytale modding. It is fully engine-agnostic and written in pure Java, allowing development and testing even before the Hytale API is available.

• Mana-based spell casting
• Cooldown system
• Consumable runes
• Multiple magic schools
• Player level requirements
• Fully testable without a game engine

1. The player selects a spell
2. SpellCaster validates:
   • Player level
   • Available mana
   • Cooldown status
   • Required rune (if any)
3. Resources (mana and rune) are consumed
4. The spell logic is executed using SpellContext

RuneCore can be tested without any game engine using a console simulation.

• Core logic never depends on the game engine
• All engine-specific code will be isolated in adapters
• Minimal refactoring will be required when the Hytale API is released
• Clear separation between logic, data, and effects

• Hytale API adapter layer
• Visual and particle effects
• Entity-based spell interactions
• Grimoire-based spell learning
• Advanced rune modifiers and variants
