How do formations work in Honkai: Nexus Anima?

Before each fight you place your Anima across three rows (front, mid, and back), then the battle plays out automatically. Durable Anima go up front and ranged or support units go in the back, and Anima that share an Aspect grant the whole team a synergy bonus. The fight is effectively decided the moment you lock in your formation.

Which row does each Trait go in?

The game has five Traits and does not publish a row for any of them, so this is a practical mapping rather than a rule: Protector and Mascot up front, Explorer in the middle, Blaster and Mastermind in the back. It follows how Aspect bonuses scale each role. Protector and Mascot are the two that gain Max Health, Mastermind gains MP, and Blaster gains attack power, so the durable roles go where the hits land.

Can I control my Anima during the battle?

No. Once you confirm the formation, every attack and skill is automatic. Your only real input is the pre-battle setup, so Nexus Anima rewards planning over reflexes.

How many Anima can I field in one formation?

Up to nine, spread across the three rows. You assemble your deck before the fight, so plan your front-line anchors, back-line damage, and shared Aspect before you commit.

How many same-Aspect Anima do I need for a synergy bonus?

It depends entirely on the Aspect, and the spread is wide. Strength pays out at a single unit, most Aspects open at two, Dark, Hate, and Memory need three, and Competition needs seven for its final tier. Check the exact ladder on the aspects page before you plan a formation around one.

What is the difference between a Trait and an Aspect?

A Trait is an Anima's combat role, one of five: Blaster, Explorer, Mascot, Mastermind, and Protector. An Aspect is its conceptual identity (Light, Dark, Hate, Memory, and so on) and decides which Anima it synergizes with. Trait is how it fights; Aspect is who it fights best alongside. Aspect bonuses often pay out differently per Trait, so the two interact.

What is the most common formation mistake?

Putting a fragile Anima (a Blaster or a Mastermind) in the front row, where it gets targeted first and dies before it helps. Keep ranged damage and field control in the back and let your Protectors and Mascots soak the hits, since those are the two Traits that Aspect bonuses scale on Max Health.

Honkai: Nexus Anima Auto-Chess Formation Guide

Honkai: Nexus Anima is a creature-collector wrapped around a formation-based auto-chess battle: you place your Anima across three rows, lock it in, and the fight resolves on its own. You never issue a command mid-fight, so the battle is won or lost the instant you confirm your setup. The whole skill is the formation. Two rules carry most of it: put each Anima in the row that matches its Trait, and stack Anima that share an Aspect so your team gets a synergy bonus.

Note: the game is in closed beta (the Evolution Test), so systems and exact numbers can change. The row roles below are stable across public coverage; treat synergy breakpoints as illustrative until launch.

Two phases: formation, then auto-battle

Every encounter runs the same loop:

Formation phase. You arrange your Anima across the front, mid, and back rows. This is where every decision happens.
Auto-battle. The game takes over. Your Anima attack, cast skills, and pick targets on their own, based on Trait, position, and synergies.
Result. Win or lose, you adjust the formation and run it back.

You can field up to nine Anima in one formation, spread across the three rows, and you assemble that lineup before the fight starts. Because there is no manual input once the battle begins, a wrong formation cannot be saved by good reactions. This is a strategy game, not an action game.

The three rows and where each Trait goes

An Anima’s Trait is its combat role, and there are exactly five: Blaster, Explorer, Mascot, Mastermind, and Protector. Put a unit in the wrong row and you waste it: a glass-cannon Blaster up front gets focused and dies before it fires; a Protector parked in the back leaves your carries exposed.

Note: the game has not published a front, mid, or back row for any Trait. The mapping below is ours, and it follows the one thing the game does state. Aspect bonuses that split their buff by role consistently put Protector and Mascot on Max Health, Mastermind on MP, and Blaster on attack power, so the durable roles go where the hits land.

Row	Traits	Job in the fight
Front	Protector, Mascot	Soak damage. These are the two Traits Aspect bonuses scale on Max Health.
Mid	Explorer	Flex layer. The deepest Trait on the roster at 22 Anima.
Back	Blaster, Mastermind	Ranged damage (Blaster, scales on attack) and field control (Mastermind, scales on MP).

A few anchors from the dex for each row, using their confirmed Aspect and Trait:

Front: Hoppelon is Competition’s headline unit but is actually an Explorer; the real front-liners in that Aspect are Furrari (Protector) and Squarel (Mascot). Dragamour (Love, Mascot) and Inkifoal (Reality, Protector) also belong up front.
Mid: Bladehound (Strength), Noctumbra (Dark), and Chimaura (Light) are all Explorers. This is the row you will have the most options for, since Explorer covers more than a quarter of the roster.
Back: Lumehart (Light, Mastermind) and Waxula (Dark, Mastermind) control the field, while Blasters like Mesmerith and Heartcease deal damage from range.

In the current beta, which row an Anima sits in matters far more than its left-to-right spot inside that row. Get the row right first; fine-tune ordering later.

Build a team in three steps

New players tend to field their five rarest Anima and lose to a focused 4-star lineup. Rarity is not a formation. Build in this order instead:

Anchor the front row. Pick one or two units that can take hits, a Protector or a Mascot. They decide how long your back row survives, which decides your total damage.
Fill the back row with damage or control. You need at least one ranged dealer or a Mastermind back there. A Blaster for damage, a Mastermind like Lumehart for field control and buffs.
Find an Aspect to share, then check its ladder. Look up your candidate Aspect on the aspects page and read the unit count its tiers actually need. Two Satiation Anima already heal the team; two Dark Anima do nothing at all, because Dark opens at three.

A worked example: a mono-Light formation

Light is one of the deeper Aspects, so it can fill every row on its own while keeping the synergy live:

Front: Apollinis (Protector), Bunmareen (Protector), Capybunner (Protector)
Mid: Chimaura (Explorer), Glampa (Explorer)
Back: Lumehart (Mastermind), Starspine (Mastermind)

That is seven of Light’s seven revealed Anima, which clears the Aspect’s top tier at six: a 60% Max Health shield applied 12 seconds into the fight. Note what the roster actually looks like once you use real Traits. Light is Protector-heavy and has no Blaster at all, so this formation is durable but short on ranged damage. Swap in whatever Light Anima you own. The shape is what matters. Drafting your own version in the formation planner is the fastest way to see the synergy and row balance at a glance.

Synergy runs on two axes, not one

Aspect is the axis that grants the bonus. Trait is the axis that decides what the bonus is worth to you, because several Aspect bonuses pay out per role rather than flat:

Aspect synergy (same Aspect) is the source of team power. Fielding multiple Anima of one Aspect trips a threshold, and each further threshold upgrades the effect. The ladders are not uniform: Strength starts at one unit, most Aspects open at two, and Competition’s last tier wants seven. Commit to one Aspect rather than scattering across many, and pick one whose tiers you can reach.
Trait mix decides how that bonus lands. Strength grants Light of the Strong as 12% Attack SPD to Blasters and Explorers, 12% MP to Masterminds, and 15% Max Health to Protectors and Mascots. Insatiability splits the same way. So the identical Aspect bonus makes a Protector-heavy board tankier and an Explorer-heavy board faster, and your Trait spread is what chooses between them.

There is no separate same-Trait stacking bonus documented in the beta, so do not plan around one. What is worth chasing is depth plus row coverage. Reality and Competition field eight Anima each and Light and Dark seven, so those four can staff several rows while keeping the synergy live. A mid-depth Aspect still works: Memory’s five Anima cover front to back, with Cinechel and Catnapir as Protectors and Camcorgi and Framamba as Blasters. Later on, Nexus Hextech augments can fake a synergy between units that do not naturally share an Aspect, which opens up off-meta builds.

Common beginner mistakes

Support in the front row. A Mastermind or a Blaster placed up front gets targeted first and dies before contributing. Keep them in the back, every time.
Ignoring synergy entirely. Treating Anima as nine separate units leaves a large team-wide multiplier on the table. Plan around an Aspect from the start.
Never re-formationing. The lineup that clears an open-world pack is not the one for a dungeon boss. Spend a few seconds checking your rows before each major fight, and move one unit if the matchup calls for it.

Bottom line

Place by Trait, build front-to-back, and commit to an Aspect. A synergized team of mid-rarity Anima in the right rows beats a pile of mismatched 5-stars.
