LegionBound Synergy Guide: All 30 Classes & Groups (2026)

LegionBound synergy is the system everything else is built around. Field both halves of a synergy pair and the forward class unlocks its synergy subclass: a stronger form that changes how that hero performs. Miss it, and you're playing each class at its floor.

30 classes across 3 loops, each with its own synergy subclass. Plus one odd case (the Peasant) that operates outside the loops entirely.

TL;DR: LegionBound synergy runs on 3 circular groups. Warrior group (14 classes), Barkeep group (11 classes), Tax Collector group (4 classes). Each class synergizes with the class before it in the loop, unlocking a synergy subclass. Start with the Tax Collector group: it's only 4 classes and you can complete the full loop early. Three of the five starters (Warrior, Wizard, Cleric) belong to the Warrior group. Ranger and Rogue go into the Barkeep group.

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 class directly before it in the loop
• Tax Collector group is easiest: only 4 classes needed to complete the full loop
• 5 starters split across 2 groups: Warrior, Wizard, Cleric in Warrior group; Ranger, Rogue in Barkeep
• Peasant is special: needs 3 evolved heroes from other groups, not loop-based synergy

How LegionBound synergy works

Every class in LegionBound belongs to a circular synergy loop. Each class has one synergy partner: the class directly behind it in the loop. Field both and meet the activation condition, and the leading class upgrades into its synergy subclass form.

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 benefits from having a Warrior (activating Warlock), it also helps the Witch behind it in the loop. 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.

Synergy pairs that work in Battle Mode may not translate to Adventure Mode's resource pressure.

The three synergy groups

Warrior group: 14 classes

The largest loop. 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 Warlock on the Sorcerer. Add Witch and you also get Hexer. You don't need all 14 to start benefiting: any adjacent pair in the table above triggers the forward 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. 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 if you hit Gunslinger you've already activated three synergy subclasses from one chain of three. The Ranger → Artificer pair is similarly efficient if you take Ranger as your starter.

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 loop and the easiest complete loop in the game. Four classes, all of them unlockable within a reasonable run length if you prioritize them.

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. The Barbarian and Brawler tend to appear mid-run, with Tax Collector and Mercenary being the less common finds depending on the mode.

Peasant: special case

Peasant (listed in-game as Protagonist) doesn't belong to any of the three circular loops. It has a synergy condition, but the trigger is different: Peasant unlocks its synergy subclass when you have 3 other heroes from different synergy groups evolved.

Peasant is a late-run target because of this. You need real investment in at least two other loops before the condition fires. Recruiting Peasant early and waiting is just wasting a slot: build your loops first and let Peasant upgrade as a side effect.

Peasant's subclass is Protagonist. Whether the power spike is worth deliberately routing toward Peasant depends on your loop composition. If you're already running heroes from both Warrior and Barkeep groups with evolution progress, Peasant upgrades naturally. If you're running a single-loop focus, Peasant stays in base form longer and contributes less.

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 directly behind your starter in the loop, synergy is already active between those two. 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 3-4 Warrior group heroes in a chain before you consider branching. Or go full Tax Collector from wave 1. Splitting across all three groups in the first 15 waves consistently produces lower-output runs than committing to one.

Step 4: Stack Ascensions within the chain

Ascensions require same-class hero pairs: two Warriors merge into one stronger Warrior, two Rogues merge into one stronger Rogue. This isn't in conflict with the synergy chain; it deepens it. A merged Warrior is still in the Warrior group, still triggering Sorcerer's Warlock subclass.

Synergy and Ascension stack on the same class: synergy gives the subclass upgrade, Ascension gives the stat multiplier. Running both on your Warrior stack is a lot more powerful than either alone. This combination is what the game is actually designed around.

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 usually shows a clear path to completion or not: the loop is short enough that you know within the first 20 waves whether you'll close it.

Watching your first lost run tells you more about synergy gaps than reading guides does.

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 your training wheels run. Four classes means you can run the full loop experiment without committing a 20-wave investment. Do one full Tax Collector run to understand what a completed loop feels like (all four subclasses active simultaneously) before scaling up to the longer loops.

Don't recruit Peasant before loop 2 unless you're already multi-loop. Peasant's synergy condition requires evolved heroes from multiple groups. Recruiting Peasant at wave 5 and waiting 30 waves for the subclass adds nothing. It's deadweight until the condition fires. Mid-run recruitment makes more sense.

Mixed groups are sometimes correct. If you're running the Warrior group and hit a Tax Collector or Barbarian that's unusually well-statted, taking them doesn't have to derail your loop. Two Tax Collector group heroes in a Warrior-primary party form a small side synergy. Barbarian triggering Berserker with a Tax Collector adjacent is a real contribution: just don't let it distract from closing your main chain.

Partial loops still improve individual heroes. You don't need to complete the loop for synergy to matter. Warrior + Sorcerer = Warlock on Sorcerer, 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 routing and a boss timer that suits players who like structured runs more than open-ended wave survival. For a different take on build-path commitment in a shorter-session format, the Die in the Dungeon tips guide covers how strategic layering works in a dungeon-crawler roguelite without the roster management overhead.

May 2026 balance patches: what changed

Several classes and charms received nerfs in May. If advice you read before May 9 references Ninja, Bard, or Cleric passive behavior, it may no longer apply.

Patch 1.05 (May 5): Three charms nerfed: Healer's Charm, Hunter's Charm, and Bloodsoaked Charm all had their scaling reduced. These were popular charm picks in Warrior and Barkeep group builds. Synergy subclass strength is unaffected; the nerfs hit supporting charm layers.

Patch 1.054 (May 9):

• Ninja (Samurai's synergy subclass): Ability cost changed from 1/3 of Action Gauge to 25%. A net nerf to Action Gauge efficiency. The Samurai → Ninja chain in the Barkeep group is still strong, but Ninja's burst output per gauge cycle is reduced.
• Bard Passive: Nerfed. Bard sits in the Barkeep group (synergy subclass: Poet, triggered by Swashbuckler). The passive reduction affects sustained output in long waves.
• Cleric Passive: Changed (not a pure nerf). Cleric is a Warrior group class (synergy subclass: Mender, triggered by Witch). The passive change altered the healing cadence. If you were building around Cleric's passive timing, test the current behavior before committing to a build guide written before May 9.

Cleric healing bug (fixed May 11): A bug caused Cleric healing to not apply correctly in certain team compositions. This was live from launch until May 11. Cleric's actual output before the fix may have been higher or lower than intended depending on configuration.

Chain Lightning known bug (as of May 12): Unresolved as of late May. Affects specific Wizard/Magus interactions in the Warrior group. If you're building around Chain Lightning procs, verify behavior in-game rather than relying on pre-patch documentation.

Frequently Asked Questions

How does synergy work in LegionBound? Synergy is circular: each class has one synergy partner (the class directly before it in its loop). Field both classes together, meet the activation condition, and the forward 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? Tax Collector group: only 4 classes. You can complete the full loop and activate all four synergy subclasses (Strongarm, Berserker, Boxer, Bounty Hunter) simultaneously. The larger groups require more party slots and run length to approach completion.

What is the Peasant class in LegionBound? Peasant (Protagonist) is outside the three circular loops. It upgrades to Protagonist synergy subclass when you have 3 other heroes from different synergy groups evolved. It's a late-run reward for multi-loop builds, not an early cluster target.

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? 30 classes plus the special Peasant/Protagonist, for 31 total. The 30 main classes split across three loops: Warrior (14), Barkeep (11), Tax Collector (4).

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.
