🛠️ Technical Summary
🧠 Architecture & data
- Oblivion-style skill engine – tracks XP per skill, per entity, per block, per food, etc. All server-side.
- Persistent storage – uses NBT / player data; XP bank and skill levels survive server restarts.

- Attribute application – live stat modifiers via server-side attribute system (no client-side cheats).
📦 Loader & dependencies

📥 Installation Guide
🧵 Fabric Installation
RECOMMENDED Best performance & stability
1. Install the Fabric Loader (recommended version for your MCPE version).
2. Download Fabric API from Modrinth or CurseForge.
3. Download EndlessMastery-Fabric-[version].jar.
4. Place both fabric-api-xxx.jar and EndlessMastery-Fabric-xxx.jar inside .minecraft/mods/.
5. Launch using the Fabric profile.
Example mods folder:
└── mods/
├── fabric-api-0.92.0+1.20.1.jar
└── EndlessMastery-Fabric-1.2.0+1.20.1.jar
└── mods/
├── fabric-api-0.92.0+1.20.1.jar

✅ Note: Fabric API is mandatory.
⚙️ NeoForge Installation
ALTERNATIVE For modpacks relying on Forge ecosystem
1. Install the recommended NeoForge version for your MCPE version.
2. Download Kotlin for Forge (KFF) – absolute requirement.
3. Download EndlessMastery-NeoForge-[version].jar.
4. Place both Kotlin-For-Forge-xxx.jar and EndlessMastery-NeoForge-xxx.jar into mods/.
5. Launch the NeoForge profile.
Example mods folder (NeoForge):
└── mods/
├── Kotlin-For-Forge-4.11.0-all.jar
└── EndlessMastery-NeoForge-1.2.0+1.20.1.jar
└── mods/
├── Kotlin-For-Forge-4.11.0-all.jar
