LegionBound Synergy List: All 42 Classes, Loops and Pairs

29 classes across 3 loops, each with its own synergy subclass, plus one odd case (the Peasant) that operates outside the loops entirely: 30 classes total at launch. Patch 1.1 (July 23, 2026) added 12 more heroes on top of that, bringing the full roster to 42. The official patch announcement does not name the new heroes or their pairings. The Steam community Hero Class Guide does, so the Patch 1.1 loops below come from that guide (it matched all 29 launch rows I cross-checked against the tables here).

Updated 2026-10-22: Correction: earlier versions called the Tax Collector loop the easiest first loop. It is the smallest, but its Tax Collector needs an achievement (beat wave 25 in the Dead Stronghold) that Steam says only 19.6% of players have, so we no longer recommend it as a starting point. On October 10 we added the 12 Patch 1.1 heroes and their two loops, corrected the May patch notes (Ninja's change is a gauge gain, not a cost), and checked the notes through Patch 1.12 (September 10), none of which change synergy rules.

TL;DR: The launch roster uses 3 circular groups: Warrior (14 classes), Barkeep (11), and Tax Collector (4), plus the independent Peasant. Each launch class has a documented prerequisite that unlocks its synergy subclass. The Tax Collector group is the smallest, but the Tax Collector itself is an achievement unlock. Three of the five starters (Warrior, Wizard, Cleric) belong to the Warrior group, while Ranger and Rogue enter Barkeep. Patch 1.1 added 12 more heroes in July 2026 (total 42), which form a 10-hero loop and a 2-hero Valkyrie loop; all 12 cost a 5,000 Skill Gem talent.

Legionbound synergy: key takeaways

• Three circular synergy loops: Warrior (14 classes), Barkeep (11 classes), Tax Collector (4 classes)
• Every class has a synergy subclass: unlocked when you field the right pair
• Synergy direction matters: Class A synergizes with the next class listed after it in the loop
• Tax Collector group is the smallest launch loop (4 classes), but the Tax Collector needs the Graveyard Shift achievement. The 2-hero Valkyrie loop from Patch 1.1 is smaller but locked behind 5,000 Skill Gems
• A partner counts as either its base class or its already-promoted form (Warrior promotes with Sorcerer or Warlock)
• 5 starters split across 2 groups: Warrior, Wizard, Cleric in Warrior group; Ranger, Rogue in Barkeep
• Peasant is special: the class guide says its synergy class, Protagonist, needs 3 other synergy heroes
• Patch 1.1 (July 23, 2026) added 12 new heroes, growing the roster from 30 to 42 total, in two new loops

How LegionBound synergy works

Each launch class in the three documented loops has one synergy partner: the next class listed in the loop. Field both and meet the activation condition, and the earlier class upgrades into its synergy subclass form. The 12 Patch 1.1 additions have their own tables further down.

Each partner slot accepts two forms. The Steam class guide lists the requirement as "Warrior: Sorcerer or Warlock", so the partner can be the base class or the class it has already promoted into. The tables show the base-class partner for brevity.

The synergy subclass is not a separate unit you recruit. It's the evolved state of the class itself: same hero slot, different ability set. A Warrior without synergy plays differently from a Warrior who has triggered Spellblade. The subclass changes skills, stat weights, or both.

The circular structure means every class is simultaneously someone's synergy trigger and someone's synergy beneficiary. A Sorcerer in your party not only unlocks its own Warlock subclass when a Witch is present, it also acts as the trigger the Warrior needs for Spellblade. Stacking multiple adjacent classes in one loop is how you create cascading synergy effects across your roster.

Loop structure matters more than individual class strength. A Rogue at base state is weaker than a Rogue running as Assassin. Chasing synergy pairs beats recruiting whoever looks biggest in the moment.

The three synergy groups

Warrior group: 14 classes

The largest loop (the LegionBound Warrior group guide has the long version). Three of the five starter classes (Warrior, Wizard, Cleric) belong here, so most players enter this loop naturally in their first few runs.

The Warrior group is the longest loop to complete, but partial chains still provide synergy value. Running Warrior + Sorcerer activates Spellblade on the Warrior. Add Witch and Sorcerer also unlocks Warlock. You don't need all 14 to start benefiting: any adjacent pair in the table above triggers the earlier class's subclass.

Three starter classes in this group means you're likely to land 2-3 Warrior group heroes in the first few waves without deliberate effort. The decision point is whether to commit to deepening that loop or branch into Barkeep.

Barkeep group: 11 classes

The mid-size loop (the LegionBound Barkeep group guide goes class by class). Two of the five starters (Ranger, Rogue) are here, and the group has a mix of physical and utility classes that work well together as a focused damage cluster.

The Rogue → Duelist → Gunslinger stretch is one of the more accessible partial chains in the Barkeep group. Rogue is a starter class, Duelist can be recruited early, and running all three activates Assassin on Rogue and Fencer on Duelist (Gunslinger needs Swashbuckler too before its own Trickshot fires). The Ranger → Artificer pair is similarly efficient if you take Ranger as your starter, unlocking Snapshot on Ranger.

Barkeep group's 11 classes sit between the Warrior group's size and the Tax Collector's speed. You can build meaningful partial loops here faster than in the Warrior group, but not as easily as the Tax Collector's tight 4-class loop.

Tax Collector group: 4 classes

The smallest launch loop (see the LegionBound Tax Collector group guide for the full breakdown). Barbarian, Brawler and Mercenary are Skill Tree nodes; the Tax Collector needs the Graveyard Shift achievement (beat wave 25 in the Dead Stronghold), which Steam's global stats show 19.6% of players have.

The full Tax Collector loop activates all four synergy subclasses simultaneously. That's Strongarm, Berserker, Boxer, and Bounty Hunter all live in one party configuration: something that takes many more heroes to achieve in either of the larger groups.

None of the five starters belong to the Tax Collector group, so you're recruiting your way in from scratch. That's the tradeoff: the loop is compact enough to complete, but you start with zero natural entries and one of the four is locked behind a wave-25 clear.

Peasant: special case

Peasant doesn't belong to any of the circular loops. It has a different dependency: the class guide says Peasant synergizes after three other synergy heroes have promoted.

Peasant is a later-run target because of this. Recruiting it early does not itself satisfy the condition; build the other promoted heroes first and let Peasant upgrade when the requirement is met.

Peasant's synergy class is Protagonist. The Steam class guide lists it as unlocked by the Rocky Start achievement (beat wave 25 in the Dusty Canyons). Do not treat Protagonist as a fourth circular-loop class.

Patch 1.1 heroes: two new synergy loops

Patch 1.1 (July 23, 2026) added 12 heroes. The official post only says each one has its own abilities and passives. The pairings below come from the Steam community Hero Class Guide, which lists every hero's synergy class and partner. The unlock cost is the same for all of them: a Skill Tree talent that costs 5,000 Skill Gems (the two Valkyries share one talent, so it is 11 talents for 12 heroes).

The 10-hero loop

The guide's Construct entry lists "Base Class: Northman", which looks like a typo in the guide, so treat the Construct row as the one to verify in the roster menu.

This loop is long, and entering it costs more than the launch loops: every link needs a 5,000 Skill Gem talent, where many launch heroes unlock from cheaper Skill Tree nodes or achievements.

The Valkyrie pair

Each Valkyrie triggers the other, and one talent buys both. It is the smallest complete loop in the game, so once the 5,000 Skill Gems are spent there is nothing left to hunt for.

Screenshot: Steam store page. The Skill Tree is where both Patch 1.1 loops are bought; this tooltip shows the 5,000-gem price format.

One r/Legionbound thread from August asks "What is the Synergy For Gambler?", and the one-word reply under it is "Necromancer". The table above agrees: Gambler promotes into Card Sharp when a Necromancer (or Summoner) is in the party.

Step-by-step: building your first synergy chain

Step 1: Pick a starter that anchors a loop.

Your first run's synergy direction starts with your starter class. Warrior, Wizard, and Cleric all anchor the Warrior group. Ranger and Rogue anchor Barkeep. None anchor Tax Collector, so if you want to run that loop, you're committing to recruiting your first two classes fresh.

For the first run, pick Warrior or Rogue. Warrior puts you in the largest loop with multiple nearby classes likely to appear. Rogue puts you in Barkeep with Duelist and Gunslinger as natural follow-ups.

Step 2: Identify your synergy direction immediately.

When you recruit your second hero, check which synergy group they're in and where they fall in the loop relative to your starter. If your second hero is the next class after your starter in the loop, your starter's synergy is already active. If they're from a different group, you're starting to split attention: which is sometimes correct but needs to be a deliberate choice, not an accident.

The class tables above show every synergy trigger relationship. Bookmark this and check it when you're deciding which recruit to take in the early waves.

Step 3: Extend the chain before branching.

The most common mistake in the first dozen runs: taking a hero from a second synergy group too early because they look individually strong. A Barbarian (Tax Collector group) joining a Warrior group party is doing base-class work (no synergy) while also pulling a party slot away from a Warrior group recruit that would activate a subclass.

Get a few adjacent Warrior-group heroes in a chain before you consider branching, or deliberately pursue the compact Tax Collector loop. The exact wave at which to branch is run-dependent; the source tables establish the dependencies, not a universal wave deadline.

Step 4: Stack Ascensions within the chain.

Ascension is a separate promotion layer. The Steam class guide describes combining synergized heroes into Ascended Units and warns that an Ascended hero does not count as the prerequisite for another synergy. Do not describe Ascension as a same-class merge or assume that an Ascended Warrior can replace the base prerequisite needed for Spellblade.

Promote a unit first when the prerequisite is available, then treat Ascension as a separate choice. The official sources confirm both systems exist, but they do not establish a universal damage multiplier or a guaranteed "stack both" outcome for every class.

Step 5: Reassess loop completion at mid-run.

By mid-run you can estimate how many remaining classes in your primary loop you're likely to see. If you've built 6 classes in the Warrior group and there are 8 more you haven't encountered, completing the full loop isn't happening this run. Shift focus: deepen what you have through Ascensions and look for what the Barkeep or Tax Collector groups can add without fracturing your core synergy chain.

If you're running the Tax Collector group's 4-class loop, mid-run assessment is easier because the dependency chain is short. Whether it completes still depends on the heroes offered in that run.

Tips

Synergy subclass names are the signal. When you see a class displaying its synergy subclass name in the hero info panel, synergy is active for that hero. If the base class name shows instead, synergy is not firing. Use this to verify your pairs are actually triggering, not just coexisting in the party.

Tax Collector loop is a mid-game project. Four classes is the shortest full loop, but the Tax Collector unlocks only after you beat wave 25 in the Dead Stronghold. Once you have it, one full Tax Collector run shows what a completed loop feels like (all four subclasses active at once).

Treat Peasant as a later target. Its synergy condition requires three other synergy heroes to have promoted. Recruiting it early does not satisfy that requirement, so make the decision around your available roster rather than a fixed wave number.

Mixed groups are sometimes correct. If you're running the Warrior group and take a Tax Collector-group hero, check the actual dependency table before calling it a synergy. Tax Collector promotes with Barbarian; Barbarian promotes with Brawler or Boxer. A shared group label alone does not activate a subclass.

Partial loops still improve individual heroes. You don't need to complete the loop for synergy to matter. Warrior + Sorcerer = Spellblade on Warrior, full stop. Every adjacent pair in the tables above is a synergy pair, even if you never build the full 14-class Warrior loop.

If you bounce off autobattlers, try the roguelite format first. LegionBound has an Adventure Mode with map choices, buildings, modifiers, rewards, and a final Endbringer decision. The official store page describes the final foe gaining power as you build; it does not frame that system as a fixed boss timer.

Balance patches that touched synergy heroes

Advice written before May 2026 may reference old values for Ninja, Bard or Cleric. These are the official Steam patch notes (Spicy Garlic Games), checked through Patch 1.12 on September 10, 2026.

Patch 1.05 (May 4): three charms were nerfed. Healer's Charm heals less per stack, Hunter's Charm now gives a 2% mark chance instead of 5%, and Bloodsoaked Charm gives 2% HP on kill instead of 5%. Synergy subclasses themselves were not changed.

Patch 1.053 (May 7):

• Ninja (Samurai's synergy subclass): the ability now grants 25% Action Gauge instead of 1/3.
• Bard passive: nerfed, now gaining 5% of the Ult Gauge needed rather than 5% of the max. Bard sits in the Barkeep group (subclass Poet, triggered by Monk).
• Cleric passive: the notes say "nerfed and buffed": 4% of the Ult Gauge needed rather than 2% of the max. Cleric is a Warrior group class (subclass Mender, triggered by Paladin).

Hotfix 1.056 (May 11): "Clerics are no longer on strike and are back to healing other heroes!"

Chain Lightning: Patch 1.057 (May 11) listed "Chain Lightning spell may not be working correctly" as a known issue. Patch 1.054 had already touched chain lightning performance, and I found no later note that mentions it again, so check it in-game before building around it.

Patch 1.1 to 1.12 (July 23 to September 10): 1.1 added the 12 heroes and previewable Ascensions, 1.11 reworked Boss Idols (covered in the LegionBound Boss Idol guide), and the later patches through 1.12 are crash and economy fixes. None of those notes change a synergy pairing.

Our take

The launch synergy system is easy to explain and hard to see in the game: it is a ring of partners, and the only thing the roster screen tells you is whether a hero has promoted. Patch 1.1 added more heroes to the same mechanism. If you are new, start a chain from your starter in the Warrior or Barkeep group, unlock the Tax Collector when you can, and finish its 4-hero loop as your first complete ring. The Valkyrie pair is the tidy late-game goal (our LegionBound tier list ranks the launch 30 only), since two heroes cover both slots. What this guide cannot tell you is which loop wins runs: the sources document pairings and unlock costs, not win rates, so treat any "best loop" claim, including ours, as an opinion.

Frequently Asked Questions

How does synergy work in LegionBound? Synergy is circular: each class has one synergy partner (the next class listed in its loop). Field both together and the earlier class upgrades to its synergy subclass. The subclass is not a separate recruit; it's the evolved state of the class itself.

What are synergy subclasses in LegionBound? Every class has a synergy subclass (a powered-up form unlocked when its synergy condition is active. Warrior's synergy subclass is Spellblade, Rogue's is Assassin, Ranger's is Snapshot. Subclasses are not separate units) they're the upgraded state of the base class when synergy fires.

Which LegionBound synergy group is easiest to build? Among the launch heroes, the Tax Collector group: only 4 classes, once you've unlocked the Tax Collector (wave 25 in the Dead Stronghold). You can complete the full loop and activate all four synergy subclasses (Strongarm, Berserker, Boxer, Bounty Hunter) simultaneously. Patch 1.1's Valkyrie pair is smaller, but needs a 5,000 Skill Gem talent.

What is the Peasant class in LegionBound? Peasant is outside every loop. Its synergy class is Protagonist, and the class guide says it needs three other synergy heroes. It is a later-run target, not a normal loop link.

What are the 5 starter classes in LegionBound? Cleric, Ranger, Rogue, Warrior, and Wizard. Warrior, Wizard, and Cleric belong to the Warrior synergy group. Ranger and Rogue belong to the Barkeep group. All five give you immediate entry into at least one major synergy loop.

How many classes are in LegionBound? LegionBound launched with 30 classes: 29 split across three loops (Warrior 14, Barkeep 11, Tax Collector 4) plus Peasant outside the loops. Patch 1.1 added 12 new heroes, for 42. They form a 10-hero loop and a 2-hero Valkyrie loop, listed in the Patch 1.1 section above.

What is the Warrior synergy group in LegionBound? The largest loop: Warrior, Sorcerer, Witch, Cleric, Paladin, Priest, Knight, Smith, Guardian, Shield Mage, Battlemage, Wizard, Druid, and Lumberjack. Three starter classes are here, making it the most naturally-entered loop in early runs.
