Root is already highly replayable because its factions do not merely start in different places or receive small bonuses. Each follows its own rules, scores differently and changes what every other player must consider. The best Root expansions build on that asymmetry with new political pressures, maps, solo options and tools for making lower-player-count games feel busier.
That makes the buying decision unusually important. A faction can reshape the whole table, while a map can alter movement and territorial control without adding much rules overhead. This guide compares the major Root expansions by the experience they create, not simply their component counts.
Underworld: The Best First Root Expansion
For most groups, The Underworld Expansion is the strongest first purchase. It adds two factions and a double-sided board, expanding both who you can play and where the war unfolds.
The Underground Duchy is a disciplined military faction built around tunnels, buildings and ministers. Its action economy becomes more powerful as it sways ministers, but losing buildings can force senior ministers out of office. That gives the Duchy an excellent rise-and-fall rhythm: it can become a major force, yet opponents have clear ways to disrupt its engine.
The Corvid Conspiracy offers a very different experience. Corvid players place facedown plot tokens that could be bombs, snares, raids or extortion. Rivals can expose them by guessing correctly, turning every token into a bluff. The Corvids are ideal for players who enjoy deception and opportunistic strikes.
The Mountain map begins with blocked paths that players can open, while its central pass creates an obvious strategic prize. The Lake map replaces some conventional movement with a ferry that carries pieces across the board. Both maps remain recognisably Root, but they make familiar factions rethink positioning. That combination of accessible factions and meaningful geography is why Underworld offers the broadest value.
Marauder: Best for Two or Three Players
The Marauder Expansion is the clearest answer for groups that often play with two or three people. Its factions have strong board presence and its hireling system fills the Woodland with additional pieces and powers.
The Lord of the Hundreds rewards aggression. Its warlord moves through the forest, mobs can destroy enemy cardboard and oppression scores points when the faction dominates clearings without rival pieces. It creates direct conflict quickly and forces the table to respond.
The Keepers in Iron are wandering knights who recover relics from forests and attempt to return them safely. Their scoring puzzle combines movement, combat and careful control of suited clearings. They are demanding, but especially satisfying for players who enjoy planning several actions ahead.
Hirelings are Marauder’s defining feature. These minor factions add life to quieter maps and temporarily grant useful abilities. The box also introduces Advanced Setup, a draft-based system that creates more varied openings. Marauder includes no map, but improves low-count games more than any other expansion.
Riverfolk: Best for Negotiation and Larger Groups
The Riverfolk Expansion thrives when the table is crowded and talkative. The Riverfolk Company sells cards, river transport and mercenary services. Its strength depends on setting attractive prices and persuading opponents to fund its plans. That creates some of Root’s funniest negotiations, although a quiet or cautious table can limit the Company’s momentum.
The Lizard Cult converts enemy buildings and warriors, recruits through revealed cards and depends on the Outcast suit for its conspiracies. Because discarded cards influence the Outcast, other players can accidentally shape the Cult’s turn. The faction is thematic and unusual, although its scoring and action constraints make it less forgiving for newcomers.
Riverfolk also supports play with up to six people and adds three Vagabond variants. It is the best choice when social bargaining is the main attraction, but Underworld or Marauder usually produces a smoother first expansion experience.
Homeland: Best for New Factions and Maps
Homeland is the newest major box and the most generous in headline content, with three factions and two maps. The Lilypad Diaspora attempts to establish a home while managing the tension between integration and militancy. The Twilight Council calls assemblies and shifts conflict toward political influence and debate. The Knaves of the Deepwood raid rivals, take warriors hostage and demand ransoms.
Its Marsh map can change size during play, while the Gorge map turns the landscape itself into a source of danger. These are bolder geographical changes than Underworld’s boards, so Homeland suits experienced groups that want the Woodland to feel unfamiliar again. It is not necessarily the best place to start, but it offers the greatest injection of genuinely new material.
Clockwork and Smaller Expansions
The Clockwork expansions replace human-controlled factions with automated opponents, making solo and cooperative Root possible. Clockwork 1 automates the four base-game factions. Clockwork 2 adds bots based on Riverfolk and Underworld factions, so it requires the relevant boxes. They are nonessential for a regular four-player group, but invaluable when a full table is unavailable.
Smaller packs can also improve the game without adding another complicated faction. The Exiles and Partisans Deck is a popular replacement for the base deck because its cards tend to create more situational, interactive decisions. The Vagabond Pack increases character variety, while the Landmarks Pack adds special locations that change the value of particular clearings.
Root also travels well across gaming tastes. A group whose fantasy interests range from role-playing games and strategy titles to fantasy gaming slots can still find a recognisable hook. What makes these expansions different is that they change relationships at the table rather than merely adding themed content. Every faction gives everyone else a new problem to solve.
Which Root Expansion Should You Buy First?
Choose Underworld if you want the best all-round upgrade: its two factions are distinctive and the Mountain and Lake maps immediately refresh the base game. Choose Marauder if you usually play with two or three people or want more reliable competitive setup. Choose Riverfolk for negotiation-heavy sessions and five- or six-player gatherings. Choose Homeland once your group already knows Root well and wants the largest leap in faction and map variety. Clockwork is the specialist choice for solo and cooperative play.
The important point is that there is no mandatory expansion path. Learn the base game first, identify what your sessions are missing and buy the box that fixes that specific gap. Root is at its best when every addition creates sharper decisions, not simply a bigger collection.
