Dune Adventures in the Imperium: Core Rulebook FAQ

Quick answer

The Dune Adventures in the Imperium core rulebook is the only book you need to run the game. It contains the full 2d20 rules, character creation, faction and house management, and GM guidance. If you want a complete Dune tabletop RPG in one volume, this is the right starting point.

What exactly is in the core rulebook?

The core rulebook is a self-contained RPG. It includes the 2d20 system rules, step-by-step character creation, a detailed look at the Imperium's factions, and a gamemaster section with advice for running political intrigue and personal conflict. You do not need any other book to play a full campaign.

How does the 2d20 system work in Dune?

The 2d20 system uses two twenty-sided dice, plus a pool of bonus dice called Momentum. You roll against a target number, and any extra successes become Momentum you can spend to improve your result or help allies. The system also uses Threat, a resource the GM spends to complicate your plans. This creates a back-and-forth that fits Dune's themes of rivalry and resource management.

What is character creation like?

Character creation is a guided process where you choose your house, role, and skills. You are not just an individual; you are part of a noble house with its own resources and enemies. The book walks you through building both your character and your house, so the whole group starts with a shared foundation.

How does gameplay actually feel?

Gameplay leans into intrigue, negotiation, and high-stakes decisions. Combat is quick and dangerous, but many sessions focus on politics, espionage, and managing your house's assets. If you want a game where a well-timed word matters as much as a blade, this delivers.

What else do I need to play?

You need the core rulebook, a set of polyhedral dice (including at least two d20s), and a group of players. The book includes everything else. The Fallout: The Roleplaying Game Dice Set from Modiphius is a good option because it includes two d20s and a full set for one player. Its blue-and-yellow design is easy to read, and the custom faces suit the 2d20 system.

Is this the same as the Dune board game?

No. The Dune board game is a competitive strategy game for 2-6 players. Dune Adventures in the Imperium is a tabletop roleplaying game where you create characters and tell stories with a gamemaster. They share the setting but are completely different experiences.

Which factions can I play?

The core rulebook covers the major factions of the Imperium, including House Atreides, House Harkonnen, the Bene Gesserit, the Spacing Guild, and the Fremen. You can play as members of any of these groups, or create your own minor house. The book gives rules and guidance for each.

Where does this fit alongside other Modiphius RPGs?

Modiphius publishes several 2d20 games, including Fallout: The Roleplaying Game. If you already own the Fallout: The Roleplaying Game Dice Set, you can use those dice for Dune as well. The systems share the same core mechanic, so the learning curve is short.

Dune RPG quick answers

Do I need the core rulebook to play?

Yes. It contains all the rules, character creation, and GM tools. There is no separate starter set required. Buy the core rulebook first.

How many players?

The game supports a gamemaster and 2-6 players, though it works best with 3-5 players. Ideal for a small group.

What dice do I need?

You need at least two d20s and a set of polyhedral dice. The Fallout dice set includes two d20s and is fully compatible. Any standard polyhedral set works.
