Chen & Mi Fu: Grizzled Edge vs Swordmancer

Physical teams in Arknights: Endfield live and die by one thing — how fast you can stack Vulnerability on an enemy and how hard you can cash those stacks in. Ever since Mi Fu arrived in Version 1.3, the Chen Qianyu + Mi Fu pairing has become the go-to physical core for most rosters, and after a lot of testing the gear answers have settled into a clear shape. This is the complete builds-and-gear breakdown we wish we had when we started: the optimal gear for Chen in Mi Fu teams, the real Grizzled Edge vs Swordmancer answer on Mi Fu, and the surrounding decisions (weapons, rotations, common mistakes) that make the whole package land.

Everything below is built around the live Version 1.3 “Sketches of Lost Heirlooms” patch, so the gear sets, weapons, and drop locations all reflect the current state of the game.

TL;DR - Key Points

Chen is the Vulnerability engine — her Lift application keeps stacks flowing for Mi Fu to consume; without her, Mi Fu drops well below her ceiling
Chen runs the Swordmancer 3-piece set — the bonus hit on Physical Status application is custom-built for a stack-applier
Chen’s best weapons depend on investment — Lupine Scarlet or Rapid Ascent for whales, Aspirant or BP Glorious Memory mid-tier, high-refinement Sundering Steel for F2P
Mi Fu runs 3-piece Grizzled Edge + one Swordmancer off-piece — not a full Swordmancer build, and not a “Redeemer Gauntlets” set (no such thing — Redeemer Gloves are standalone with no set bonus)
Pick the Swordmancer fourth piece by goal — NAV Beacon kit for max damage, Light Armor for faster Ultimate gain
Skip crit entirely on Mi Fu — her Crush damage can’t crit, so Strength / ATK / Physical DMG% / Arts Intensity are the real priorities
Crush hits ~3x as hard as Breach but ignores Skill DMG% — Arts Intensity and Physical DMG% are the scaling stats
Qingbo recipes drop from Gear Template Crates in Wuling; the Positioning Kit T1 blueprint is in Sword Vault Dale

How Vulnerability Actually Works (The Foundation)

Before any of the gear choices make sense, you need the system they’re built on. Physical operators in Endfield do not trigger elemental Arts reactions. Instead, they apply the Vulnerable debuff (up to 4 stacks) and then convert those stacks with one of four Physical Statuses.

Lift and Knock Down each add a Vulnerable stack while dealing bonus Stagger and crowd-controlling the target.
Crush consumes every Vulnerable stack on the target for one enormous burst of Physical damage. The more stacks consumed, the bigger the hit.
Breach consumes every stack, deals damage, and applies a Physical-DMG-Taken debuff to the enemy whose strength scales with the stacks consumed.

One number underpins all of it: each point of Arts Intensity increases pre-mitigation Physical damage by 1%, so Arts Intensity buffs Crush, Breach, Lift, Knock Down, and Stagger alike. Hold onto that fact — it explains nearly every gear choice in this guide, and it’s the load-bearing reason Grizzled Edge ends up where it does on Mi Fu.

Status	Effect	Stacks
Lift	Adds a stack + lifts the target	+1
Knock Down	Adds a stack + knocks the target down	+1
Crush	Consumes all stacks for big Physical damage	-all
Breach	Consumes all stacks + applies Physical-DMG-Taken debuff	-all

The team you want is one operator who can generate stacks fast and one operator who can cash them in for a big number. Chen and Mi Fu fit that mold almost too perfectly.

Chen Qianyu’s Role in a Mi Fu Team

Chen is a free 5★ Physical Sword Guard you pick up during Chapter 1, and she is the engine that makes Mi Fu work. Her job is to apply Lift over and over to build Vulnerability fast, then hand a fully-stacked target to your Crush DPS. Her Battle Skill (Ascending Strike) applies Lift directly, and her Combo Skill (Soar to the Stars) re-applies Lift when the enemy is already Vulnerable, adding another stack.

She scales primarily off Agility and Strength, plus Physical DMG Bonus. She is a sub-DPS first and a stack-generator always — and in a Mi Fu team, that second job is the one that matters most, because Mi Fu can barely generate Vulnerability on her own (her Ultimate self-applies a single stack, and that’s basically it).

This is also why the Mi Fu best teams breakdown calls Chen “non-negotiable” — without her, Mi Fu’s MOVE 3 just doesn’t fire, and you end up with a melee Guard that hits like a wet noodle.

Chen’s Best Weapons by Investment Level

There is no single “correct” Chen weapon — it depends entirely on what you’ve actually got in your arsenal. Here’s how we rank them across investment tiers.

Tier	Weapon	Why
Whale	Lupine Scarlet (6★)	Top damage ceiling on Chen
Premium	Rapid Ascent (6★)	Strong vs Staggered enemies
Premium	Eminent Repute (6★)	Strong team-attack% profile
Signature	Aspirant (6★)	Ultimate Damage Bonus baseline
Battle Pass	Glorious Memory (Protocol Pass sword)	ATK%, Crit, higher base stats, Ult Damage profile
F2P (BiS)	Sundering Steel (5★, refined)	Within a few % of 6★ options at max refinement
Off-pick	Grand Vision	Fine if you already have it

Three takeaways:

Whales and heavy spenders chase Lupine Scarlet or Rapid Ascent. Either is excellent, with Eminent Repute as a close third.
Her signature, Aspirant, remains a great pick, particularly for its Ultimate Damage Bonus.
Battle pass route: Rossi’s Protocol Pass sword Glorious Memory is one of the best non-signature choices. It carries the same Ultimate Damage Bonus profile as Aspirant but layers on ATK%, Crit Rate%, and higher base stats, and it slots onto Chen beautifully.
F2P and budget players: high-refinement Sundering Steel (5★) is the answer. Maxed out, it performs within a few percent of the 6★ options, which makes it the most sensible long-term craft for most accounts.

The short version: chase Lupine Scarlet or Rapid Ascent if you’re whaling, otherwise grind Sundering Steel to high refinement and don’t lose sleep over it.

Chen’s Gear Set: Swordmancer Is Home

Chen’s recommended endgame set is the Tier-4 Swordmancer pack, and its 3-piece bonus reads like it was written for her:

Wearer’s Stagger Efficiency Bonus +20%. After the wearer applies a Physical Status, the wearer also performs 1 hit that deals 250% ATK of Physical DMG and 10 Stagger. Trigger cooldown: 15s.

Because Chen is constantly applying Lift (a Physical Status), she procs that bonus hit on cooldown while keeping enemies staggered for the rest of the team. Pair the 3-piece Swordmancer set with two matching kits, prioritizing Agility, Strength, Crit, and Physical DMG% on her sub-stats.

A quick myth-bust, since this trips a lot of people up: there is no “Redeemer Gauntlets” Swordmancer upgrade. The real item is Redeemer Gloves, and it’s a standalone piece with no set bonus at all — it has nothing to do with Swordmancer, so don’t build around it expecting set synergy.

You can technically run a full Qingbo set on Chen for the −15% Combo Skill cooldown and the Skill DMG buff, but it’s not her main build. Swordmancer does more for a stack-generator than Qingbo does, so treat Qingbo on Chen as an experiment, not a target.

Mi Fu’s Kit: Converting Stacks Into Crush Burst

Mi Fu is the 6★ Physical Greatsword Guard who released in Version 1.3, and she is a pure Crush DPS. Her whole identity is converting the Vulnerability that Chen builds into city-leveling burst.

Her Battle Skill, Qingbo Triplex, is a three-move chain:

Cloudtrapper — a gap-closer that pulls her to the target (costs 100 SP, refunds 50).
Trail and Mangle — applies Crush (50 SP).
World Splitter — a massive Crush-type hit that unlocks only when Trail and Mangle consumes 3 or more Vulnerability stacks (50 SP).

Her Combo Skill, Fists of No Regrets, auto-fires once the enemy hits 3+ Vulnerability stacks. It applies Physical Susceptibility and shortcuts her straight to Trail and Mangle, letting her skip Cloudtrapper and save SP. The optimal flow is straightforward: let Chen build to 3-4 stacks, fire the Combo Skill, then chain into Trail and Mangle and World Splitter.

Two of Mi Fu’s Potentials are worth knowing:

Potential 1 (Restless Watch): Combo Skill cooldown −2s, plus a stronger and longer Physical Susceptibility effect.
Potential 2 (Kinesthesia of Harmony): Strength +20 and Arts Intensity +16. If you’ve seen “+60 Arts Intensity” quoted anywhere, that figure is wrong — it’s +16.

One critical detail for gearing: Mi Fu’s Crush damage cannot crit — she sits at the base 5% crit rate, and her main payoff hit doesn’t roll the crit dice. Crit stats are wasted on her. Build Strength, ATK, Physical DMG%, and Arts Intensity instead.

Mi Fu’s Best Weapon Choices

Her 6★ signature, Amaranthine Tassel, is the clear best-in-slot. It grants a large unconditional Physical DMG bonus, adds Arts Intensity when she applies Physical Susceptibility, and gives a stacking Physical DMG bonus on Crush that scales with the Vulnerability stacks consumed — every line on it feeds her core loop.

If you don’t have the signature, Ancient Canal is a solid F2P-friendly Greatsword option. One naming clarification that catches people out: Ancient Canal and Amaranthine Tassel are two different weapons — Ancient Canal is its own lower-rarity pick, not a source for or refinement of the Tassel.

Weapon	Rarity	Notes
Amaranthine Tassel	6★	BiS signature — Physical DMG, Arts Intensity on Susceptibility, stacking Crush bonus
Ancient Canal	(lower)	Solid F2P-friendly Greatsword option

Don’t chase crit rolls on a Greatsword build for Mi Fu — since her Crush can’t crit, ATK%, Physical DMG%, and Arts Intensity are what actually scale her payoff hit.

Grizzled Edge vs Swordmancer on Mi Fu: The Real Answer

This is the question that matters, and the answer is that you run both — three pieces of Grizzled Edge plus one Swordmancer off-piece. What changes is which Swordmancer piece you slot.

Grizzled Edge is the new set that debuted in Version 1.3 alongside Mi Fu, and its 3-piece bonus is built for exactly her kind of damage:

Wearer’s ATK +8%. When the wearer applies Crush or Breach, the wearer gains Physical DMG Dealt +(6% × max Vulnerability stacks consumed from one enemy) for 20s. If the target already has Physical Susceptibility, is Staggered, or has attached Originium Crystals, that buff is increased to 1.5×.

Read that carefully and the symmetry is obvious. Mi Fu consumes big stacks of Vulnerability with Crush, and her own Combo Skill applies Physical Susceptibility — which means she almost always triggers the 1.5× condition on herself, with no extra setup required. The buff scales directly with the thing she’s already doing on every rotation.

Why not a full old-Swordmancer build on Mi Fu? Because Grizzled Edge’s Physical-DMG-per-stack-consumed scaling does far more for a Crush dealer than Swordmancer’s stagger-focused bonus. Swordmancer is fantastic on a stack-applier like Chen; Grizzled Edge is the set built for the stack-consumer. Use each on the operator it was designed for — they pair across the team, not on one operator.

Choosing the Fourth Piece: NAV Beacon vs Light Armor

The 3-piece Grizzled Edge bonus does the heavy lifting, so the fourth slot is where you pick your flavor.

Build	Fourth Piece	Use When
Maximum damage	Swordmancer NAV Beacon kit	Pure DPS ceiling, default for most rosters
Faster Ultimate	Swordmancer Light Armor	You want Mi Fu’s Ultimate (Vulnerability self-apply) back faster

Maximum damage build: 3-piece Grizzled Edge + Swordmancer NAV Beacon kit. This is the raw-output setup and the default for most rosters.
More ultimate gain: 3-piece Grizzled Edge + Swordmancer Light Armor. Mi Fu’s only self-application of Vulnerability comes from her Ultimate, so if you want it back faster, the Light Armor’s Ultimate Gain Efficiency is worth the small damage trade. Light Armor over Heavy Armor specifically for that reason — Heavy Armor doesn’t carry the Ult Gain line.

If your team already has Chen plus another stack-applier (Pogranichnik, Lifeng, Rossi in a hybrid frame — see the Rossi team comps guide), you can lean NAV Beacon comfortably; if it’s a leaner physical core where Mi Fu’s Ultimate is your main self-applied stack, Light Armor is worth the trade.

Crush vs Breach: Which Status to Consume With

Since both Chen and Mi Fu revolve around consuming stacks, knowing Crush from Breach is essential.

Crush deals exactly 3× the damage of Breach on a single instance at equal Status Level (300% vs 100% ATK at Level I, scaling up to 750% vs 250% at Level IV). It’s pure, immediate burst.
Breach deals less but applies a Physical-DMG-Taken debuff (roughly +12-24% depending on Status Level) that amplifies all subsequent physical hits.
Crush scales with Arts Intensity and Physical DMG%, but not Skill DMG%. This is exactly why Grizzled Edge (ATK, Physical DMG, Arts Intensity) suits Mi Fu and generic Skill-DMG sets don’t — and it’s also why her World Splitter, which counts as Crush, ignores Skill-DMG buffs entirely.

Rule of thumb:

On tanky enemies, open with Breach to plant the susceptibility debuff, then Crush into the amplified window.
On squishy enemies that die in one burst, skip Breach and just Crush — the amp window is wasted if the target is already dead.

It’s the same logic physical team strategy in general leans on — front-load burst, don’t waste setup on targets that die during the setup.

How to Obtain the Qingbo Positioning Kit

The Qingbo set is the combo-cooldown set, and its 3-piece grants Combo Skill Cooldown Reduction +15% plus Skill DMG +20% per cast (up to 2 separately-timed stacks). To craft it, you need the recipes:

Qingbo Gear Set recipes come from Gear Template Crates in the Wuling region. Some crates mix in pieces from other sets, so you may need to open several before you’ve collected everything.
The Qingbo Positioning Kit T1 blueprint can be picked up while exploring Sword Vault Dale, the sixth Wuling sub-region added in Version 1.3 (southeast of Qingbo Stockade, gated behind the “Deep Vaulted Steel” side mission).

In our runs the blueprint shows up in the later sections of Sword Vault Dale — clear the deeper exploration nodes and check chests and blueprint pickups there. If you want to pin the exact node, a current interactive map of Sword Vault Dale will confirm the spot.

Builds by Player Type

The Chen + Mi Fu core can be built at almost any investment level. Here’s where to land depending on where your account actually is.

Brand-new / Early Account

Chen Qianyu: Sundering Steel (5★) at the highest refinement you can afford. Swordmancer 3-piece as soon as the recipes drop.
Mi Fu: Ancient Canal as a placeholder Greatsword, Grizzled Edge 3-piece + any Swordmancer off-piece. Don’t sweat NAV Beacon vs Light Armor yet — you’ll feel the difference later.
Priority: Finish Chen’s Swordmancer set before refining Sundering Steel past mid ranks — the stack-generation floor matters more than her solo damage.

Mid-Game / BP Player

Chen Qianyu: Glorious Memory (Protocol Pass) once you’ve banked the BP. Swordmancer 3-piece with Agility-priority kits.
Mi Fu: Amaranthine Tassel if you pulled it, otherwise a high-refined Greatsword from your existing pool. Lock in 3-piece Grizzled Edge + Swordmancer NAV Beacon as the default.
Priority: P1 Mi Fu becomes attractive here — the -2s Combo Skill cooldown and stronger Physical Susceptibility is the only dupe most non-whales should consider.

Endgame / Whale

Chen Qianyu: Lupine Scarlet, Rapid Ascent, or Eminent Repute. Swordmancer 3-piece, max-refined kits, Agility / Strength / Crit / Physical DMG% rolls.
Mi Fu: Amaranthine Tassel at the refinement you can stomach, 3-piece Grizzled Edge + NAV Beacon for max damage, swap to Light Armor for Ult-heavy content.
Priority: P0 + signature beats P1 + BP weapon by a wide margin. Don’t chase P2 over the sig.

The Standard Chen + Mi Fu Rotation

Putting it all together, here’s the loop the build is designed around.

Lead with Chen to apply Lift and build Vulnerability toward 3-4 stacks. Her Combo Skill re-applies Lift on Vulnerable targets for an extra stack.
Once the target is sufficiently stacked, Mi Fu’s Fists of No Regrets Combo Skill auto-triggers, applying Physical Susceptibility (which feeds Grizzled Edge’s 1.5× condition).
Chain into Trail and Mangle, then unleash World Splitter for the Crush payoff — the bigger the stack count consumed, the larger the Grizzled Edge buff she carries into the next rotation.
Repeat, weaving Chen’s Combo Skill back in to keep stacks flowing, and time Mi Fu’s Ultimate for the extra self-applied Vulnerability when your DPS window opens.

If you’ve been running the Mi Fu & Camille build guide frame, this is the version optimized specifically around Chen rather than around a Camille Heat axis — same Crush-burst payoff, just with the stack-generation engine swapped out.

Common Mistakes and Pitfalls

After a few weeks of running the pairing, the same handful of mistakes show up over and over.

Building Mi Fu with crit stats. Her Crush can’t crit. Every point you sink into Crit Rate or Crit Damage is wasted, since her main payoff hit rolls 5% by default and doesn’t move with crit substats.
Running a full Swordmancer build on Mi Fu. Tempting (set’s right there, Chen’s wearing it), but Grizzled Edge’s per-stack scaling outpaces Swordmancer’s stagger bonus on the consumer. Set Swordmancer aside on Mi Fu beyond the single off-piece.
Hunting “Redeemer Gauntlets” as a Swordmancer upgrade. It doesn’t exist. Redeemer Gloves are a separate standalone piece with no set bonus. Don’t waste catalysts trying to slot it into Swordmancer expecting synergy.
Equipping Mi Fu without a real stack-applier on the team. Without Chen / Pogranichnik / Lifeng / Rossi feeding her Vulnerability, World Splitter just won’t unlock. Mi Fu solo is roughly 60% of her ceiling.
Buffing World Splitter with Skill DMG%. Crush ignores Skill DMG% entirely. Stack Arts Intensity, Physical DMG%, and ATK — not the generic Skill DMG buffs that work on most other carries.
Quoting “+60 Arts Intensity” for Mi Fu P2. It’s +20 Strength and +16 Arts Intensity. The +60 number is a long-running misquote.
Treating Aspirant as a Rossi weapon for cross-pollination. Aspirant’s Ultimate-damage profile fits Chen because her Ult applies Lift; it does not fit Rossi (whose Ult is 100% heat), where it’s actively a downgrade vs Glorious Memory.

Watch List: What Would Change These Builds

A few external factors could shift the optimal builds before the next major patch lands.

Contingency Contract modifier waves. If a CC season punishes single-element comps, expect a Rossi-hybrid pivot that re-routes Chen’s stack-applier role through a slightly different stat priority.
Endministrator rework. A reworked Endmin could change which Crush-consumer best pairs with Chen, especially in F2P comps where Endmin currently coexists awkwardly with Mi Fu (the two share consumption duties and split the resource).
Camille’s full SP/sec numbers as Phase 2 settles. If Camille’s SP economy lets Mi Fu fire World Splitter more often per minute, the Ultimate-gain Light Armor swap becomes less essential and NAV Beacon becomes default-everywhere.
A 1.4 Physical 6★. A new Physical operator slotted into Chen’s role would re-rank her tier table, but it would not break the Swordmancer-on-applier / Grizzled-Edge-on-consumer split itself.
Amaranthine Tassel rerun cadence. Signature reruns typically arrive 9-12 months out — a faster cadence would push more accounts toward the full BiS shell faster than the F2P weapon table assumes.

Final Verdict

Chen’s job in a Mi Fu team is Vulnerability generation. Build her on the Swordmancer 3-piece set and arm her with Lupine Scarlet or Rapid Ascent if you’re invested, or a high-refinement Sundering Steel if you’re F2P.
Mi Fu’s best gear is 3-piece Grizzled Edge plus one Swordmancer off-piece — NAV Beacon for maximum damage, Light Armor for faster ultimate gain. Grizzled Edge beats a full old-Swordmancer build on Mi Fu because its buff scales with the stacks she consumes. Skip crit stats entirely.
Crush hits ~3× as hard as Breach and ignores Skill DMG%, so prioritize Arts Intensity and Physical DMG%. Breach first on tanky targets, straight Crush on squishy ones.
Qingbo recipes drop from Gear Template Crates in Wuling, with the Positioning Kit T1 blueprint waiting in the depths of Sword Vault Dale.

Get the gear right and the Chen / Mi Fu core becomes one of the most satisfying physical teams in the game — Chen stacks, Mi Fu shatters. Try the setups, tweak the Breach-vs-Crush calls for your own content, and let the Vulnerability do the work.

FAQ

Is Chen Qianyu mandatory for a Mi Fu team? Functionally, yes. Mi Fu’s MOVE 3 (World Splitter) requires Trail and Mangle to consume 3+ Vulnerability stacks, and Mi Fu herself only self-applies one stack on Ultimate. Without a dedicated applier — Chen, Pogranichnik, Lifeng, or Rossi in hybrid frames — Mi Fu sits around 60% of her ceiling. Chen is the most accessible of those options because she’s a free 5★ from Chapter 1.

Should I run Mi Fu with full Swordmancer like Chen? No. The 3-piece Grizzled Edge bonus scales with the Vulnerability stacks she consumes, and her Combo Skill self-applies Physical Susceptibility to hit the 1.5× condition. Full Swordmancer doesn’t keep up on a Crush consumer. Use Swordmancer on the stack-applier, Grizzled Edge on the stack-consumer.

Are Redeemer Gauntlets the next Swordmancer piece? No — “Redeemer Gauntlets” is a misnomer that’s been floating around community guides. The real item is Redeemer Gloves, and it’s a standalone piece with no set bonus at all. Don’t build around it expecting Swordmancer synergy.

Why do crit stats not work on Mi Fu? Her Crush damage instances can’t crit. She sits at the base 5% crit rate, and the World Splitter payoff hit doesn’t roll the crit dice. Stat budgets are better spent on Strength, ATK, Physical DMG%, and Arts Intensity, which all scale her actual damage.

Is Sundering Steel really competitive with the 6★ swords on Chen? At max refinement, yes — within a few percent of Lupine Scarlet, Rapid Ascent, and similar options. For F2P accounts it’s the most sensible long-term Chen craft, since Chen’s primary contribution is Vulnerability application rather than raw damage ceiling.

Should I use NAV Beacon or Light Armor as Mi Fu’s fourth piece? NAV Beacon kit gives the highest pure damage and is the default. Switch to Light Armor when you specifically want Mi Fu’s Ultimate back faster (it’s her only self-applied Vulnerability stack) — typically in content where you can’t sit a full rotation in the buff window. Light Armor specifically, not Heavy Armor.

Does Skill DMG% buff World Splitter? No. World Splitter counts as a Crush instance, and Crush scales with Arts Intensity and Physical DMG% but ignores Skill DMG%. This is one of the most common buff misallocations on Mi Fu — generic “skill damage” gear effects don’t move her payoff hit.

Where does the Qingbo Positioning Kit blueprint actually drop? Inside Sword Vault Dale, the new Wuling sub-region added in 1.3, gated behind the Deep Vaulted Steel side mission. The blueprint shows up in the deeper exploration nodes. Sword Vault Dale also feeds back into the broader Wuling region’s Gear Template Crates, which is where the rest of the Qingbo recipes come from.

Is Aspirant or Glorious Memory the right Chen pick for a BP player? Glorious Memory carries the same Ultimate Damage Bonus profile as Aspirant but layers on ATK%, Crit Rate%, and higher base stats. For most BP players it’s the better grab when both are available, especially because the BP route makes it the cheaper long-term refinement target.

How does Mi Fu’s P2 actually scale her damage? Potential 2 (Kinesthesia of Harmony) adds +20 Strength and +16 Arts Intensity — not +60 Arts Intensity, which is a misquote that keeps recirculating. The Strength bumps her shield budget and Final Strike multipliers, while the 16 Arts Intensity adds ~16% pre-mitigation Physical damage. It’s a stat-stick dupe, not a kit-changer.

CHEN & MI FU: GRIZZLED EDGE VS SWORDMANCER
