  • Durable & Portable: Injection-molded terrain made to last and easy to transport.

Save Time & Money – Modular Terrain Combos

For new DMs or anyone who wants maximum value without piecing things together one at a time, Combos are the smart choice.
Perfect for new Dungeon Masters who don’t yet know which encounters they’ll need.
Makes an excellent gift for any DM, giving them everything they need to run diverse adventures.

Includes sets like Dragon’s Lair, Bandit Camp, Lich Sanctorum, Curse Lands, and Village of the Lost—complete with diverse terrain features.

These combos offer the best bang for your buck, letting you dive straight into immersive storytelling without buying sets individually.

Take Full Control – Build Your Own Custom World

1. Identify Your Encounter Scene

Choose a Core Set to fit your world: dungeon crawl, castle siege, cavern exploration, or wilderness skirmish.

2. Select Add-on Kits and Expansions

Customize with rooftops, rivers, stairs, bridges, pillars, interchangeable seasonal trees, and more.

3. Create Infinite Possibilities

Reconfigure, repaint, and relaunch your layouts for new adventures every session.

Ready-to-Play Additions for Any DM

Kits

Kits are standalone small sets that work with any table setup, making them an essential addition to every DM’s toolkit. Whether it’s rivers, Jail Cells (what player hasn’t ended up in one?), timeworn bridges, or cultish obelisks and altars in twilight thick pine forests - Kits instantly expand your storytelling options. They’re the easiest way to drop something new into your campaign without overthinking the setup.

Build Bigger, Invite More Players

Expansions

Expansions are designed to extend and enhance specific Core Sets or Combos. Add magic-blasted caverns walls to a spelunking mission, or diagonal walls to add complexity to your dungeon or castle layout, or use the Multi-floor support expansion with the Castle Sets’ acrylic platforms to give the ability to do freestanding aerial combat - each Expansion increases your battlefield size and storytelling flexibility. Perfect for DMs who want to host larger more complex encounters or run longer, more immersive campaigns without repeating the same setups.

Next-Level Detail & Immersion

Decor

Decor is where you bring your world to life with fine details and atmospheric touches. Think stone pillars with flickering torches, Metallic Doors to add visual pop and character to dungeons and castles, or Castle Decor to personalize the pennant flags of the castle walls - that elevate your tabletop environments from simple structures to a more fully realized environment. This is what transforms your sessions from “Nintendo 64 pixels” to “PlayStation 5 realism” overnight. No other company in the market offers this level of customization and replayability at the price point that Dirt Cheap Dungeons does.
