Claimed Spawn Shield

A lightweight NeoForge mod for Minecraft 1.21.1 that enhances FTB Chunks by preventing hostile mobs from spawning inside claimed chunks, while still allowing special events such as Enhanced Celestials Blood Moons to function as intended.

It also includes optional compatibility with Apotheosis, allowing you to disable Elite and Invader spawns inside claimed chunks.

✨ Features

🛡️ Prevents hostile mobs from spawning inside FTB Chunks claimed areas.
🌕 Automatically allows hostile mob spawning during Enhanced Celestials Blood Moons.
⚔️ Optional support for Apotheosis:
- Disable Elite mob spawns within claims.
- Disable Invader mob spawns within claims.
⚡ Lightweight with minimal performance impact.
🔧 Designed specifically for modded survival servers and multiplayer worlds.

📋 Requirements

Component	Version
Minecraft	1.21.1
NeoForge	21.1.235
FTB Chunks	2101.0+

Optional Compatibility

Enhanced Celestials (for Blood Moon support)
Apotheosis (Elite/Invader spawn protection)

🧠 How It Works

Whenever a hostile mob attempts to spawn, Claimed Spawn Shield checks whether the spawn location is inside an FTB Chunks claimed area.

✅ Outside a claim: Mob spawning behaves normally.
❌ Inside a claim: The spawn is cancelled.
🌕 During an Enhanced Celestials Blood Moon: Spawns are allowed, preserving the intended challenge of Blood Moon events.
⚔️ Apotheosis Elite/Invader spawns: Can optionally be blocked even if they use custom spawning mechanics.

This allows players to keep their bases safe without removing the excitement of special world events.

🎮 Perfect For

Multiplayer servers
Private modpacks
Adventure worlds
Community servers
Players who want safer claimed bases without disabling Blood Moon gameplay
