🌟 Key Features

🚩 Tactical Chunk Wars & Conquest

• Border-Based Warfare: Declare war on neighboring hostile claims from the border. Deep core territory cannot be bypassed without securing border chunks first!
• Sector Wedge Conquest: Take control of strategic wedges of connected territory in a single, hard-fought campaign.

🛡️ Balanced Capture & Anti-Zerg Mechanics

• Presence-Driven Capture: Attackers advance the siege progress bar by holding the contested zone; defenders push it back by defending the territory.
• Anti-Zerg Protection: Diminishing returns prevent massive zergs from instantly steamrolling smaller, well-fortified teams. Skill and endurance decide the victor!
• AFK Protection: Idle players do not contribute to siege progress.

⏰ Fair-Play Raid Windows & Cooldowns

• No 4 AM Offline Raids: Define exact server raid hours (e.g., 18:00 - 22:00) so battles only happen when players are online and ready to fight.
• Strategic Cooldowns: Configurable attack and defense cooldowns prevent spam declarations and give defeated parties time to regroup.

❤️ War Lives & Live Scoreboard

• High-Stakes Combat: Every warrior receives limited war lives per siege. Lose your lives, and you're out of the battle!
• Sidebar HUD: Real-time scoreboard display keeps everyone informed of remaining lives and combat status.

🗺️ Full Xaero's Map Integration

• Fair-Play War Markers: View active conflict zones and timers directly on Xaero's Minimap and Xaero's World Map.
• Right-Click War Start: Simply right-click any eligible enemy border chunk directly on Xaero's World Map to initiate a siege!

🔔 Discord Webhooks

• Automatically broadcast war declarations, phase transitions, and final siege outcomes directly to your server's Discord channel with rich embeds.

⚔️ How Sieges Work

  [ /war start ] ────► [ Preparation Phase ] ────► [ Active Battle ] ────► [ Resolution ]
  Target border chunk     Defenders & attackers      Fight for zone;           100% = Captured!
  or Xaero right-click    gear up & rally           drain enemy lives         Timeout = Defended!

1. Declaration: A party declares war on an adjacent rival chunk using /war start or the Xaero World Map menu.
2. Preparation: A countdown gives defenders time to rally their allies, build fortifications, and prepare gear.
3. Active Phase: The chunk becomes contested! Normal claim restrictions relax for combatants:
   • Stand inside the zone to capture or defend.
   • Watch the capture bossbar and sidebar lives.
   • Glowing effects keep combatants visible and prevent hiding in corners.
4. Resolution:
   • If attackers reach 100% progress, the chunk is claimed by the attackers!
   • If defenders hold out until time expires or deplete enemy lives, the siege fails and peace is restored.
