⚔️ Siege Core: Base Invasions ⚔️

Defend your base. Survive the waves. Protect the Core.
Siege Core: Base Invasions is a Fabric mod that turns your Minecraft base into the target of dangerous monster invasions, boss fights, elite enemies, invasion events, and endless progression.

🏰 What is Siege Core?

Siege Core: Base Invasions adds a full base-defense system to Minecraft. Craft and place a powerful Siege Core inside your base, build your defenses, invite your team, and prepare for dangerous enemy waves.

Over time, your base generates Threat Points. Once the threat level is full, an invasion is prepared. After a configurable delay, enemies begin attacking your base, your team, and most importantly: your Siege Core.

If the Core survives all waves, your base advances. If the Core falls, the invasion is lost.

🔮 The Siege Core

The Siege Core is the heart of your base and the main target of every invasion.

📍 Registers your base location
❤️ Tracks Core health
👥 Stores owner, members, and managers
⚠️ Generates Threat over time
🌊 Starts wave-based invasions
📊 Opens a custom Core Overview UI
🛡️ Can be repaired and upgraded through progression

Only the owner can break the Core, and each player can only own one active Siege Core.

💎 Crafting Recipe

The Siege Core is crafted with Diamond Blocks and a Redstone Block:

D D D
D R D
D D D

D = Diamond Block
R = Redstone Block

The recipe is intentionally expensive because the Core is the central block of the invasion system.

⚠️ Threat System

Outside of active invasions, your base builds up Threat. Threat can be generated by time, activity near the base, monster kills, and ore mining.

By default, an invasion is prepared when your base reaches:

3500 Threat Points

Once the Threat bar is full, players receive a warning and the invasion starts after a configurable preparation delay. By default, this delay is 15 minutes, giving your team time to prepare.

The Threat progress is shown through a bossbar while no invasion is active.

🌊 Stages and Waves

The Siege Core has five normal stages. Each stage increases the number of waves in an invasion.

Stage	Waves
Stage 1	3 Waves
Stage 2	6 Waves
Stage 3	9 Waves
Stage 4	12 Waves
Stage 5	15 Waves

The Core only advances to the next stage after the entire invasion has been completed successfully.

Between waves, there is a configurable countdown. By default, the delay between waves is:

90 seconds

♾️ Infinity Mode

Want an endless challenge? Enable Infinity Mode directly at the Siege Core.

♾️ Progress beyond Stage 5
📈 Reach Infinity Levels up to 100 by default
💀 Enemies become stronger over time
🌊 Maximum wave count is configurable
🏆 Supports leaderboard progression

Infinity Mode is perfect for multiplayer servers and long-term survival worlds.

👹 Enemies

Siege Core adds many enemy types to invasion waves.

🧟 Zombies
🏹 Skeletons
🕷️ Spiders
🏴 Pillagers
🪓 Vindicators
🐗 Ravagers
🦇 Phantoms
💀 Wither Skeletons
🧟 Giant Zombies

Enemies scale with the Core stage and can become stronger through armor, damage multipliers, elite variants, boss modifiers, and invasion events.

⭐ Elite Monsters

From higher stages and Infinity levels onward, special Elite Monsters can appear.

Elite Enemy	Effect
Armored Zombie	More health, better armor, tanky frontline enemy
Berserker Vindicator	Fast and dangerous axe attacker
Flame Skeleton	Stronger ranged skeleton
Storm Phantom	Faster aerial attacker
Brute Pillager	Stronger crossbow enemy
Plague Zombie	Dangerous melee zombie variant

Elite enemies are shown in the custom HUD and have visible names in-game.

👑 Boss Fights

Every third wave is a Boss Fight. During boss fights, the boss health is shown with a dedicated bossbar.

Current boss types include:

🧟 Giant Zombie — a massive zombie boss with heavy melee pressure
🐗 Ravager Boss — a dangerous siege beast
💀 Wither Skeleton Champion — a deadly late-game boss

🔥 Boss Modifiers

Bosses can spawn with random modifiers, making fights more unpredictable.

Modifier	Effect
Enraged	More damage and movement speed
Shielded	More health and armor
Regenerating	Heals during combat
Summoner	Summons additional enemies
Explosive	Creates an explosion on death

🌘 Invasion Events

Invasions are not always the same. Special events can appear during waves and change the battle.

Event	Effect
🌕 Blood Moon	More undead enemies and stronger monsters
🌫️ Dark Fog	Dark atmosphere and darkness effects near the base
🦇 Sky Attack	More Phantoms and aerial attacks
🐗 Siege Breaker	More Ravagers and Core-focused pressure
🏹 Arrow Rain	More Skeletons and Pillagers
⭐ Elite Surge	Higher Elite Mob chance

Events are shown in the custom invasion HUD and announced to the team.

🎁 Rewards

After every successfully completed wave, each online team member receives:

💚 Emeralds
✨ Experience

By default:

1 Emerald per completed wave
25 XP per completed wave

Bosses can also have configurable loot pools. Siege enemies do not drop their equipped armor or weapons, preventing easy gear farming.

🔧 Core Repair

The Core can be repaired manually using resources.

Item	Healing
Iron Ingot	+25 Core HP
Diamond	+50 Core HP

Core healing cannot exceed the maximum Core HP.

💥 Core Destruction

If the Core reaches 0 HP during an invasion, the invasion is lost.

When the Core is destroyed, TNT is spawned around it and detonated. This creates a real consequence for failing to protect your base.

The mechanic cannot be disabled, but values such as TNT radius, count, and fuse time are configurable.

🧭 Core Access Protection

The Core must remain accessible. If the Core is completely blocked or built in, threat generation and invasion countdowns can pause.

This prevents players from hiding the Core inside sealed blocks and forces bases to stay defendable.

🛡️ Offline Protection

Threat can require team members to be online

Siege Core is designed to make Minecraft bases matter again.
