UNDERGROUND DUCHY

Subterranean Empire Strategy Guide

Faction Overview

The Underground Duchy are subterranean moles who have built a vast network beneath the woodland. They tunnel between clearings, establish burrows, and manage noble obligations while staying largely hidden from surface conflicts. Their strength comes from mobility and avoiding direct confrontation.

Key Mechanic: Tunnel Network

The Duchy builds an underground tunnel system connecting clearings across the map. This provides unique movement advantages and allows them to appear where enemies least expect. Tunnels are the foundation of all Duchy strategy.

Understanding the Tunnel Network

Tunnels are your highways beneath the woodland. They connect burrows and allow rapid troop movement while remaining hidden from surface factions.

Underground Network

Build tunnels to connect your burrows and move unseen

Tunnel Construction

Building an effective tunnel network requires strategic planning:

  • Connect Burrows: Link your strongholds for rapid reinforcement
  • Strategic Placement: Access key clearings without surface presence
  • Defense Network: Create multiple routes to avoid bottlenecks
  • Economic Routes: Connect resource-rich areas efficiently

Remember: Tunnels are hidden from enemies and provide unique mobility!

Noble Management

Your noble moles have different personalities and abilities. Managing their needs and leveraging their strengths is crucial for maintaining your underground society.

Early Game Strategy (Turns 1-4)

Initial Network

Establish your first tunnel connections strategically:

  • Corner Start: Begin in corner clearings for safety
  • Resource Access: Connect to valuable clearings
  • Avoid Conflict: Stay away from early military activity
  • Plan Ahead: Consider future expansion routes

Goal: 3-4 connected burrows by turn 3

Noble Priorities

Focus on satisfying key nobles early:

  • The Banker: Essential for economic growth
  • The Chronicler: Provides card advantage
  • The Brigadier: Military expansion when ready
  • The Duchess: Point generation in mid-game

Balance: Don't neglect any noble completely

Burrow Placement

Choose burrow types based on immediate needs:

  • First Burrow: Usually Market for economic foundation
  • Second Burrow: Library for card flow
  • Third Burrow: Citadel for military presence
  • Location: Connected clearings with resources
Early Game Fragility

The Duchy starts slowly and builds momentum over time. Don't rush into conflicts or try to compete with aggressive factions early. Focus on building your infrastructure and staying hidden underground.

Mid Game Strategy (Turns 5-7)

Network Expansion

With established foundations, expand aggressively:

  • Build tunnels to key strategic clearings
  • Establish burrows in contested areas
  • Create multiple routes for redundancy
  • Connect distant parts of the map

Goal: 6-8 burrows connected by tunnels

Surface Emergence

Begin asserting presence on the surface:

  • Use tunnel mobility for surprise attacks
  • Establish control in uncontested clearings
  • Support weaker factions against dominators
  • Protect key tunnel entrances

Noble Optimization

Maximize noble benefits through strategic play:

  • Banker: Fund rapid expansion
  • Chronicler: Maintain large hand size
  • Brigadier: Launch coordinated attacks
  • Duchess: Begin serious point generation

Late Game Strategy (Turn 8+)

Victory Push

With established network, focus on winning:

  • Point Generation: Duchess and burrow scoring
  • Surface Control: Rule key clearings for dominance
  • Disruption: Use mobility to prevent enemy victories

Target: Reach 30 points through diverse strategies

Tunnel Warfare

Leverage your unique mobility advantages:

  • Strike where enemies are weakest
  • Appear suddenly in multiple locations
  • Retreat through tunnels when threatened
  • Control key strategic points

Endgame Flexibility

Adapt strategy based on board state:

  • Dominance Victory: Control clearings of one suit
  • Point Victory: Maximize burrow and noble scoring
  • Disruption: Prevent other factions from winning
  • Alliance: Support factions against common threats
Underground Advantage

Your late-game strength comes from unpredictability. Enemies can't easily predict your movements or target your assets. Use this to stay one step ahead and strike when opponents least expect it.

Common Mistakes to Avoid

Neglecting Nobles

Unsatisfied nobles reduce your action economy and cause unrest. Always plan to meet their basic demands, even if it means sacrificing other goals.

Poor Tunnel Planning

Building tunnels without long-term vision wastes actions. Plan your network to connect valuable locations and provide multiple strategic routes.

Premature Surface Presence

Emerging too early makes you a target before you're ready. Build your infrastructure first, then assert surface control when you can defend it.

Ignoring Defense

Burrows are valuable targets that need protection. Always maintain adequate warriors, especially at key network nodes and economic centers.
