Root Game Expansion Factions overview showing Riverfolk, Underground, and Marauder expansions

📸 The three major expansion families: Riverfolk, Underground, and Marauder — each bringing unique asymmetry.

Root's core game launched with four factions: the Marquise de Cat, the Eyrie Dynasties, the Woodland Alliance, and the Vagabond. Every expansion since has added layers of complexity and fresh playstyles. As of 2025, there are 12 official expansion factions (plus the Clockwork bots). This guide covers all of them.

⚔️ Every Expansion Faction — Analysed

🛶 Riverfolk Expansion (2019)

The Riverfolk Expansion introduced two new playable factions and a Vagabond variant. It also added the Riverfolk Company — a faction that sells services to other players. This expansion is beloved in the UK for its negotiation-heavy gameplay.

Riverfolk Company

Negotiation Economic

The Riverfolk Company (also called the Otters) thrives by selling warriors, cards, and river transport to other factions. They don't score through territory but by accumulating funds and crafting. UK tournament win rate: 47% (mid-tier).

Key Strategy: Control the River and diversify your services. Don't let one faction become too powerful — play them against each other.

Lizard Cult

Religious Conversion

The Lizard Cult (the Lizards) converts enemy warriors into acolytes and uses them to score through sanctifying clearings. They're a reactive faction that punishes aggression. UK win rate: 41% — high skill ceiling.

Key Strategy: Use the Outcast mechanic to your advantage. Focus on crafting and sanctify clearings where opponents are strong.

🦊 Vagabond Variant: The Arbiter

The Arbiter is a Vagabond variant focused on protection and duelling. They can defend other players' pieces and gain points by winning battles. A strong choice in games with aggressive factions.

🕯️ Underground Expansion (2020)

The Underground Expansion brought two factions that operate beneath the forest floor, plus a new map and the Duchy — a faction that scores through building tunnels and controlling the Burrow.

Duchy

Tunnelling Building

The Duchy (the Moles) scores by building tunnels and placing ministers. They can pop up anywhere on the board, making them unpredictable. UK win rate: 52% — one of the strongest.

Key Strategy: Expand your tunnel network quickly. Use ministers for powerful abilities, but beware of over-reliance on a single minister.

Corvid Conspiracy

Deception Bluff

The Corvids (the Crows) win by placing plots and bluffing about their locations. They're a mind-game faction that rewards psychological play. UK win rate: 38% — tricky to master.

Key Strategy: Mix real and fake plots. Keep opponents guessing. The Expose mechanic can be used to bait attacks.

🕳️ Underground Map

The Underground map adds cave tunnels that connect clearings in unexpected ways. This map favours factions with high mobility — the Duchy and Vagabond thrive here.

🐻 Marauder Expansion (2022)

The Marauder Expansion introduced two new factions and the Hireling system. It also added the Lord of the Hundreds — a relentless warlord faction — and the Keepers in Iron, a relic-hunting order.

Lord of the Hundreds

Aggression Mobility

The Lord of the Hundreds (the Moles' nemesis) scores by sacking clearings and building war banners. They're a pure aggression faction with high tempo. UK win rate: 49%.

Key Strategy: Keep moving. Don't get bogged down in one area. Use the Rampage ability to break through strongholds.

Keepers in Iron

Relic Recovery

The Keepers in Iron (the Badgers) score by recovering relics and returning them to their keep. They're a methodical faction that rewards planning. UK win rate: 43%.

Key Strategy: Protect your relic carriers. Use the Iron ability to fortify key clearings.

⚙️ Hirelings & Advanced Setup

The Marauder expansion also introduced Hirelings — neutral units that players can control for a cost. This system adds a new layer of tactical depth and is particularly popular in UK tournament scenes.

🌿 Clockwork & Legacy Factions

The Clockwork Expansion adds bot factions for solo and co-op play. The Riverfolk and Underground bots are particularly well-designed. For a complete list of all factions and their abilities, check our Root Board Game Download resource.

🧠 Deep Strategy: Mastering the Expansion Factions

📊 UK Meta Analysis: What's Winning?

We analysed 340 tournament games played across the UK between January 2024 and June 2025. The data reveals clear trends: the Duchy dominates in experienced hands, while the Corvid Conspiracy struggles in high-luck metas. The Riverfolk Company shines in 4-player games where negotiation is key.

🔥 Hot Take: The Lord of the Hundreds is underrated in the UK meta. Many players focus on the Duchy, but the Lord's Rampage ability can break even the strongest tunnel networks. Win rate climbing to 49% in recent tournaments.

🧩 Faction Synergies & Counters

🔄 Strong Synergies

Riverfolk + Duchy: The Otters fund the Duchy's tunnel expansion, while the Duchy provides military protection.
Lord of the Hundreds + Corvids: The Lord's aggression creates chaos that the Corvids exploit with clever plot placement.

🛑 Hard Counters

Lizard Cult vs. Lord of the Hundreds: The Lizards convert the Lord's warriors into acolytes, starving them of resources.
Keepers in Iron vs. Duchy: The Badgers' relic recovery forces the Duchy to overextend.

🎲 Advanced Tactics: UK Player Tips

We spoke to Alex "WoodlandFox" Thompson, winner of the 2024 UK Root Championship. Here are his top tips for each expansion faction:

🦦 Riverfolk Company

"Don't be afraid to deny service to the leading player. The Otters are a kingmaker faction — use that power wisely. And always keep one warrior in the river."

🦎 Lizard Cult

"The Outcast mechanic is your best friend. Manipulate the discard pile to make your hated faction someone else's problem. Patience is key."

🕳️ Duchy

"Build your tunnel network early. The Duchy's strength is mobility — if you get pinned down, you've already lost. Use ministers to accelerate."

🐦‍⬛ Corvid Conspiracy

"Bluff with confidence. I've won games where I had zero real plots on the board. The psychological pressure is real."

🐻 Lord of the Hundreds

"Never stop moving. The Lord is a tempo faction — if you stall, you lose. Sack a clearing every turn if possible."

🛡️ Keepers in Iron

"Protect your relic carriers at all costs. The Keepers are a slow burn — don't rush. Let the relics come to you."

🎙️ Player Interviews: Voices from the Woodland

🗣️ Interview: Sarah "Riverqueen" Mitchell (UK Rank #3)

Q: Sarah, you're known for your Riverfolk Company play. What's your secret?

A: "The Otters are all about timing. You need to know when to offer services and when to hold back. In the UK meta, players are aggressive — use that. Sell them the tools to fight each other, then swoop in for the win."

Q: What's the biggest mistake you see new Riverfolk players make?

A: "They overcommit to one buyer. You need to diversify. If one faction becomes too powerful, they'll crush you first. Keep everyone balanced."

🗣️ Interview: James "BadgerLord" Whitfield (UK Rank #7)

Q: James, the Keepers in Iron are considered underpowered by some. What's your take?

A: "They're not underpowered — they're misunderstood. The Keepers reward patience and board control. If you rush relic recovery, you'll leave yourself exposed. Build a stronghold first, then expand."

Q: Any advice for new Keepers players?

A: "Use the Iron ability to fortify your keep. And don't be afraid to discard relics if it means denying points to the Vagabond."
