Best Soldier 11 Build Guide

Written by Phạm Ngọc Bảo Châu · Updated 6 Oct 2026

Playstyle Overview

Soldier 11 is an S-Rank Fire Attack Agent from the Standard Banner. She's basically free, yet she can keep up with some limited Agents. Everything revolves around Fire Suppression: time your Basic Attacks well and she unleashes stronger Fire slashes. After EX Special Attack: Fervent Fire, a Chain Attack or her Ultimate, her Basic and Dash Attacks are guaranteed to trigger Fire Suppression for 15s or 8 uses.

She needs few resources, so she can stay on-field for a long time and still burst hard during Stun. Her best partners are Stunners like Norma, Lighter or Dialyn, plus Astra Yao. Just build CRIT and ATK. The catch: she wants well-timed inputs and leans on specific teammates and limited W-Engines.

Best W-Engines

Heartstring Nocturne

ATK 713 · CRIT Rate 24%

Her best option by a clear margin. You get a huge amount of unconditional CRIT Rate and CRIT DMG, plus Fire RES ignore on her Chain Attacks and Ultimate.

String & Melody ›

CRIT DMG increases by 50%. When the equipper enters the battlefield, or activates a Chain Attack or Ultimate, they gain 1 stack of Heartstring. Each stack of Heartstring allows the equipper's Chain Attack and Ultimate to ignore 12.5% of the target's Fire RES, stacking up to 2 times and lasting 30s. Repeated triggers reset the duration.

*Stats shown are at Base level.

Cordis Germina

ATK 713 · CRIT Rate 24%

Seed's signature: high CRIT Rate, and at max stacks her Basic Attacks and Ultimate ignore 20% DEF.

Sprouting Core ›

Increases CRIT Rate by 15%. When the equipper deals DMG with a Basic Attack or EX Special Attack, they gain 1 stack of a buff. Each stack increases the equipper's Electric DMG by 12.5% up to 2 stacks. Each stack lasts 40s. The duration of each stack is calculated separately.

Can trigger once per use of a skill. At 2 stacks, the wearer's Basic Attack and Ultimate DMG ignore 20% of enemy DEF.

*Stats shown are at Base level.

Myriad Eclipse

ATK 713 · CRIT Rate 24%

Hugo's signature. Soldier 11 can't use its special buff, but the CRIT Rate main stat and big unconditional CRIT DMG still make it a strong pick.

False Personas ›

Increases CRIT DMG by 45%. When using an EX Special Attack, Chain Attack, or Ultimate to deal Ice DMG, the equipper gains the Absolute Zero Death Sentence effect for 3s. While Absolute Zero Death Sentence is active, the character ignores 25% of the enemy's DEF when landing a hit.

*Stats shown are at Base level.

Severed Innocence

ATK 713 · CRIT DMG 48%

Soldier 0 - Anby's signature: lots of CRIT DMG, and Soldier 11's Basic Attack-heavy playstyle keeps its stacks up with ease.

Tranquil Blossom ›

CRIT DMG is increased by 30%. When the equipper lands a hit with a Basic Attack, Special Attack, or Aftershock, they gain 1 stack of a buff. Each stack increases the equipper's CRIT DMG by an additional 10%, stacking up to 3 times. The effect lasts for 30s, with each stack's duration calculated separately, and can only be triggered once per use of a skill. With all 3 stacks, the equipper's Electric DMG increases by 20%.

*Stats shown are at Base level.

The Brimstone

ATK 684 · ATK% 30%

Her signature and the most used option. Outside Stun it's at full stacks almost all the time, only dipping during burst combos. It beats every A-Rank option and even some limited ones, so it's both strong and easy to get.

Scorching Breath ›

Upon hitting an enemy with a Basic Attack, Dash Attack, or Dodge Counter, the equipper's ATK increases by 3.5% for 8s, stacking up to 8 times. This effect can trigger once every 0.5s. The duration of each stack is calculated separately.

*Stats shown are at Base level.

Starlight Engine

ATK 594 · ATK% 25%

A dependable free option for Attack Agents: ATK% main stat plus an ATK buff after Dodge Counters or Quick Assists.

Knight Plummel ›

Launching an Assist Attack increases the equipper's ATK by 12% for 12s.

*Stats shown are at Base level.

Best Drive Discs

Puffer Electro

4-pc ›

2-piece:

PEN Ratio +8%

4-piece:

Ultimate DMG increases by 20%. Launching an Ultimate increases the equipper's ATK by 15% for 12s.

Woodpecker Electro

2-pc ›

2-piece:

CRIT Rate +8%

Best when you have Dialyn: one Chain Attack turns into an Ultimate right at the start of the combo and her Decibel Ultimate comes later, so the buff stays up for the whole Stun. Without Dialyn it falls off, since Soldier 11 relies on double Chain Attacks; Astra Yao can partly make up for it with extra Chains.

Woodpecker Electro

4-pc ›

2-piece:

CRIT Rate +8%

4-piece:

Landing a critical hit on an enemy with a Basic Attack, Dodge Counter, or EX Special Attack increases the equipper's ATK by 9% for 6s. The buff duration for different skills are calculated separately.

Puffer Electro

2-pc ›

2-piece:

PEN Ratio +8%

A solid all-rounder: she's always using Basic Attacks and Dodge Counters, so uptime is decent. You'll need to manage it a bit, since her expensive EX Special makes the third stack hard to keep.

Dawn's Bloom

4-pc ›

2-piece:

Increases Basic Attack DMG by 15%.

4-piece:

Increases Basic Attack DMG by 20%.

When equipped by an Attack Character, using an EX Special Attack or Ultimate will further increase Basic Attack DMG by 20% for 25s.

Repeated triggers reset the duration.

Woodpecker Electro

2-pc ›

2-piece:

CRIT Rate +8%

A steady Basic Attack DMG boost that suits her empowered 5th Basic Attack after her Potential Unlock; 2-piece Woodpecker Electro adds CRIT Rate. Her costly EX Special makes the 4-piece bonus a little fiddly to manage.

Inferno Metal

4-pc ›

2-piece:

Fire DMG +10%

4-piece:

Upon hitting a Burning enemy, the equipper's CRIT Rate is increased by 28% for 8s.

Hormone Punk

2-pc ›

2-piece:

ATK +10%

Adds Fire DMG and a big CRIT Rate bonus against Burning enemies; you'll need strong Anomaly builders like Yuzuha or Lucy to keep it active.

Endgame Stats

ATK: 2800 – 3000+
HP: 9500+
DEF: 800+
CRIT Rate: 80%+
CRIT DMG: 140%+

Aim for 80%+ CRIT Rate and around 140% CRIT DMG, then put the rest into ATK. On Disc 5, PEN Ratio or ATK% usually beats Fire DMG; Anomaly Proficiency is only a minor useful substat.

Skill Priority

Core Skill
›Basic Attack
›Special Attack
›Chain Attack
›Dodge
›Assist

Her Core Skill boosts Fire Suppression and Basic Attack is her main damage source, so level those two first. Special Attack is also high priority, then Chain Attack/Ultimate, since their multipliers are huge during Stun. Dodge is worth leveling because Dash Attacks trigger Fire Suppression too; leave Assist for last.

Best Teams for Soldier 11

Most Used Teams Right Now

Her most used Deadly Assault team and the top recommendation. Norma shares her Fire Attribute to activate her Additional Ability and adds extra Chain Attacks for more guaranteed Fire Suppression, while Astra Yao covers all-round buffs.

Soldier 11

Lighter

Astra Yao

Lighter is her best Fire Stunner: he massively boosts Fire DMG, lowers enemy Fire RES and deals huge amounts of Daze.

Other Stun Options

Soldier 11

Norma Hollowell

Sunna

Her highest-scoring Deadly Assault team on average; Sunna takes Astra Yao's Support slot, giving ATK buffs and healing.

Soldier 11

Dialyn

Astra Yao

Depending on her build, Dialyn can be her best Stunner: an extra Ultimate every Stun, longer Stuns and a range of buffs. With Heartstring Nocturne and Astra Yao's extra Chains, the burst more than makes up for losing the Additional Ability.

Soldier 11

Trigger

Astra Yao

Trigger provides off-field Daze and Aftershocks plus a big Stun DMG Multiplier increase, leaving the field to Soldier 11. Ju Fufu or Pulchra work in a similar way.

F2P Team

Soldier 11

Ben

Nicole

Rocketboo

Ben and Nicole are both free. Ben shares her Fire Attribute, builds Daze and activates her Additional Ability, while Nicole shreds DEF and groups enemies. Nicole's own Additional Ability stays off in this team.

Best Bangboo for Soldier 11

Rocketboo is the main pick for both the premium and F2P teams (it needs two Fire Agents, such as Norma or Ben); you can swap in Cryboo (same condition), Sumoboo or Avocaboo.

In the F2P team, Bagboo and Avocaboo also work; Avocaboo's healing makes it great early on.

Mindscape Cinema

Which Mindscapes Are Worth It?

M2 is the best place to stop since it directly boosts damage every time Fire Suppression triggers. M6 is also a very strong upgrade thanks to its Fire RES ignore. M4 only matters if you struggle to keep her alive, and M1 is held back by its long cooldown; M3 and M5 only add skill levels, so they're not counted.

M1
On entering combat or switching in with under 40 Energy, she's refilled to 80 (once every 50s). Handy, but the cooldown is long.
M2
Each Fire Suppression adds 3% Basic Attack, Dash Attack and Dodge Counter DMG, stacking up to 12 times. That's a very big damage upgrade.
M4
Fire Suppression on hits 1–3 or Dash Attacks raises Anti-Interrupt and cuts DMG taken by 18%, and on hit 4 grants invulnerability. Only worth it if you struggle to keep her alive.
M6
EX Specials, Chain Attacks and Ultimates grant 8 Charge stacks; each Fire Suppression consumes one to ignore 25% of the target's Fire RES.

Rapid HeatRecommended

When Soldier 11 enters combat or switches in, if her Energy is less than 40, her Energy is recovered to 80. This effect can trigger once every 50s.

Long-term high-intensity combat training allows Soldier 11 to complete mastery of her regulatory systems.

She will always strive to ensure that she's in the best shape for each and every battle.

Scorching ConvergenceRecommended

When triggering Fire Suppression, Basic Attack, Dash Attack, and Dodge Counter DMG increases by 3%, up to 12 stacks, lasting 15s, with the duration of each stack calculated separately.

"She may look cold and hard, like a big ice cube... But actually, she's scalding hot inside, like a blazing fire."

— From an anonymous soldier of the Obsidian Division

Elite Soldier

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2

Soldier 11 always expects the most from herself, no matter if it's in training or physical combat. That is how she maintains her combat prowess.

Indulgent BlazeRecommended

If Fire Suppression is triggered during the 1st, 2nd, or 3rd hit of Soldier 11's Basic Attack or a Dash Attack, Anti-Interrupt Level increases and DMG received is reduced by 18% during skill activation.

If Fire Suppression is triggered during the 4th hit of her Basic Attack, she becomes invulnerable during skill activation.

She envies fire. And these smoldering flames will always help her.

Perfect Soldier

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2

The road from elite to exemplar is long and difficult, but Soldier 11 grits her teeth and perseveres, as if there's something pushing her towards the goal of becoming a perfect soldier...

Scorching FlowRecommended

When Soldier 11 uses her EX Special Attack, Chain Attack, or Ultimate, she gains 8 stacks of Charge (max 8 stacks).

When Fire Suppression is triggered, 1 stack of Charge is consumed, causing the current move to ignore 25% of the target's Fire RES.

The flames of the sword distorted the air with their heat. Her movements grew ever more impassioned, as if that heat seeped into her spirit with every breath, igniting her thoughts.

Story

Agent Profile: Soldier 11

Soldier 11 is a member of the New Eridu Defense Force.

She currently serves as a primary responder in the Obol squad, Obsidian Division. Soldier 11 is a code name – her real name remains unknown.

"...My name? I gave it up long ago."

It's only a reminder of my past, and the past makes you weak."

Soldier 11 is a fan of spicy food, and likes the super-spicy noodles served at Waterfall Soup.

It's worth noting she currently calls us by a different name every time she greets us.

Additional information regarding Soldier 11 is still being obtained.

Cooperation Notes:

Belle

Cats, super spicy noodles, going on missions, and everyone in Obol Squad... These are what make up Soldier 11's current life... I hope we one day hold a place in her heart as well~

Wise

I'm sure we will! But really, I just hope Soldier 11 remembers our name someday...
