⚔️ Base Defense 1.1.0 - The Undead Legion & Siege Warfare Update

This major update transforms Base Defense into a full-scale tactical siege experience, introducing military battalion deployments, custom raid bosses, allied companion mechanics, and structural base physics!

💀 The Undead Legion & Bosses

• The Undead Legion: Day 10 triggers an organized battalion assault advancing in military formation:
  • Undead Phalanx: Shield-bearing frontline units that deflect 100% of frontal arrows and projectiles.
  • Undead Arbalests: Tactical crossbow firing lines firing piercing bolts over the shield wall.
• Moon Commander (Mini-Boss): Colossal 1.35x vanguard leader in lunar plate armor. Wields the Moonsteel Halberd and blows a war horn to rally legion units with Speed and Strength.
• God of the Undead (Cataclysm Boss): Towering 1.85x Netherite-obsidian titan descending during rare Grand Eclipse events. Emits an Undead Bastion aura buffing nearby legion troops and wields The Sword of Hell.

🗡️ Artifacts & Companion Mechanics

• The Sword of Hell: Legendary endgame blade dealing heavy damage and inflicting Wither II.
  • Necrotic Resurrection: Slaying enemies raises them as allied Shadow Minions who fight alongside you, protect your base, and assist you in combat.
• Moonsteel Halberd: Heavy two-handed polearm with sweeping cleave damage that disables blocking shields for 4 seconds.
• Ammunition Synergy: Full compatibility for Shock Arrows (chain lightning) and Explosive Bolts across vanilla Bows and Crossbows.

🌙 Dynamic Night & Raid System

• Nightly Skirmishes: Calm scout waves every normal night for steady Core Shard income.
• Blood Moons (5% chance): High-tempo siege waves with wall-shattering Breachers and the Blood Behemoth.
• Legion Raids (Every 10 Days): Periodic waves are disabled in favor of a massive, synchronized rank-and-file battalion marching on the base at midnight.
• The Grand Eclipse: Rare apocalyptic convergence deploying the High Command and full legion strike forces.

🧱 Structural Siege Physics & Progression

• Anti-Cheese & Crumbling: Siege mobs progressively crack and shatter obstructing stone bricks, wood, and barricades. Water moats no longer wash away siege mobs, and narrow pillars are knocked down.
• Advancement Tree: Added a dedicated 15-advancement progression tab under deepslate tiles.
• Repair Hammer Synergy: Repair damaged, cracked, and crumbling fortifications back to full strength.
