Dwarf fortress how to fill in holes


Dwarf Fortress is a captivating and complex game where you manage a colony of dwarves deep underground. One common challenge in the game is dealing with holes and gaps in your fortress’s structure. These gaps can lead to accidents, floods, or even invasions. In this guide, we will explore the art of filling in holes in Dwarf Fortress to help you create a safer and more efficient underground haven for your dwarves.

Understanding the Problem

1. Identifying Hole Types

Before you can fill in a hole, you need to understand its type. Common hole types in Dwarf Fortress include:

  • Mining Holes: These are gaps created when you dig out minerals or gems. They can be deep or shallow and often expose valuable resources.
  • Collapse Holes: These result from cave-ins or poor construction. They can be dangerous and destabilize your fortress.
  • Water Holes: Sometimes, water sources breach your fortress. These holes can flood your tunnels and rooms.
  • Channeling Holes: These are gaps you create intentionally by channeling down or across levels. They are part of fortress planning.

2. Assessing the Risk

Not all holes are equal in terms of risk. Assess the potential dangers associated with each hole type. Consider factors like cave-ins, flooding, or creature invasions that may occur due to these holes.

3. Safety First

Before you begin filling in a hole, ensure the safety of your dwarves. Restrict access to dangerous areas, and provide alternative routes to essential locations.

4. Walling and Flooring

The most basic method of hole filling is to construct walls and floors. This is suitable for most hole types, including mining holes and collapse holes. Ensure the structural integrity of your construction to prevent further collapses.

5. Floodgates and Bridges

To deal with water holes, floodgates and retractable bridges are invaluable. Place them strategically to control the flow of water or seal off flooded areas.

6. Stairs and Ramps

For channeling holes, use stairs and ramps to create safe passages. Dwarves can navigate these slopes without difficulty, and it’s a practical way to traverse levels.

7. Reinforcements

In areas prone to frequent holes, consider reinforcing walls and ceilings with sturdy materials like stone or metal. This can prevent collapses and protect your dwarves.

Tips for Success

8. Plan Your Layout

During fortress design, plan your layouts carefully to minimize the creation of unnecessary holes. Strategic placement of walls and supports can prevent accidents.

9. Keep an Eye on Digging

When mining, use designated mining zones and be cautious with designations. Overambitious digging can lead to excessive holes.

10. Prioritize Infrastructure

Focus on critical infrastructure first, like food storage, workshops, and bedrooms. This ensures that essential areas are secure.
