Botzu's Quick Evaluation

+ Trait: Regular attacks deal damage twice
+ Talent: When deployed, all Skills with [On Attack] and [When Hit] Charge Type gain 1 SP over time
+ E2 Talent; +ATK, +DEF, +Physical Dodge
+ Excellent when paired with other Operators that have [On ATK] or [When Hit] charge skills
+ S2: Strong burst group assassination
+ S3: Great multi-target and Boss killing
= While her attacks hit twice, they only charge 1 SP per attack, and her ATK stat is lower than other Guards to compensate, putting her at a disadvantage against high DEF enemies
= As a Nuker, her best Skills are instant bursts, and she lacks Skills for sustained damage
- Expensive Deploy Cost
- [On-Attack] charge Skills with moderate SP Costs can be slow to charge

Operator Overview

“Such evil must be stopped, and by any means necessary.”

Onee-san, tsundere, waifu, and all-around badass of the early Arknights story, Ch’en is not just a high-ranking Lungmen official but also a 6★ Specialist
Dualstrike Guard with an outstanding and diverse kit.

Of her two Talents, Ch’en’s first, Scolding is potentially her most potent: it causes all allies with Skills of the  “Attacking Enemy” or “Getting Hit” SP Charge Type to gain 1 SP every 5 seconds. This can be used solo or stacked with other SP-gain abilities to allow more frequent Skill use.  Just call her the SP Energizer Bunny (though maybe not within her hearing).

Along with her trait that allows her to deal damage twice with each attack, what makes Ch’en so unique is the variety and effectiveness of her Skills.  Her role in battle changes based on the Skill she uses, and she is solid at all of them. 

  • Her Skill 1, Sheathed Strike, boosts her single-target DPS with a nice Attack steroid and adds fairly consistent stuns.
  • If she equips her Skill 2, Chi Xiao - Unsheath, Ch’en turns into a multi-target burst assassin.  The Skill deals a lot of Physical and Arts damage to multiple enemies in range (both ground and aerial!), and at max Skill Level it is available to use immediately on deploy.
  • Need some multi-attack burst with crowd control?   Ch’en’s ready with her Skill 3, Chi Xiao - Shadowless, which divides several hits between targets over a large area and ends with a Stun.  Use it and watch low-Defense bosses melt before your eyes!

Ch’en’s greatest weakness is that she hasn’t joined me yet pays for her amazing Skills by only being able to charge them when she is attacking.  Although her Talent does soften the blow, it can be frustrating during breaks in battle watching Ch’en get no closer to her next Skill use while other Operators are charging.  Ignore Ch’en at your peril, however. Given the chance, her skillful swordplay can completely dominate the battlefield.

Newbie Tier List Explanation

Good damage early game but falls off in later content. Needs Skill Mastery to really excel. New players are better off using development resources elsewhere until if/when they are sure they want to fully invest.

Elite Promotion Discussion

  • 3rd Skill - Chi Xiao - Shadowless - Ch’en goes into Ninja-Teleport-Slaughter mode and instantly delivers 10 hits to a large range with a huge multiplicative ATK bonus.  If anything survives this onslaught, it gets rewarded for its toughness with a decent length stun. The only real trouble is that she needs to be attacking something to charge her SP, which can be frustrating during lulls in fighting or if you would prefer to have her away from the frontline assault point.  Her other skills offer different utility that will be preferable depending on the situation.
  • Skill 2: Chi Xiao - Unsheath (M3) - At Mastery 3, this skill starts with 20/20 SP, letting Ch’en instantly use it on deployment.  This allows players to use her as a pseudo-Specialist to deploy and burst down enemies with large AoE Physical and Arts damage.  She can then be retreated for additional uses.  Since this hits aerial units as well, it can even catch any leaked drones heading for home!

  • Talent 2 - Blade Art - An ok self-stat increase. Nothing game-changing.

  • Talent 1 upgrade - Scolding - A boost to her very useful first Talent.  It doesn’t seem like much at first glance, but it is a 20% increase in effectiveness.

Ch'en's default Guard form has never been all that strong, but her value has only dipped further as time has gone on, especially with the introduction of her alter form, the most powerful unit in the game. But still, her Guard form does hold some small niche meta value still, and she gains a small bit of new life thanks to the Roguelike mode.

Most players should not spend resources on Guard Ch'en at all, though both her S2 and S3 have quite valuable Masteries for those intent on using her. For her S2, Mastery allows for instant activation on deployment. Her S3 provides some strong damage that can be dished out at range with some pretty rare invulnerability attached which occasionally finds an end-game niche.

She can work well in the Roguelike mode thanks to various relics that work really well with her skills. That gives her slightly higher grades than a unit of her meta caliber normally gets. But she is still a waifu-only raise. There are simply too many good Guards who do the same role better or cheaper.

Integrated Strategies Tier List Explanation

General IS Notes

+ Powerful burst damage.
+ S2: Helidroppable. Decent panic buton with high damage that catches air.
+ S3: Big burst of mixed damage on single targets.
- Low uptime due to high SP costs and Offensive charging.
- Generally worse than other Operators at both holding lanes and bursting enemies.
- S2: Struggles to take down anything later on.

IS2 Specific Notes

Very reliant on relics to catch up to speed with other Operators. Doesn't perform well against most bosses in the gamemode due to their gimmicks.

Good Relics

Wrath of Siracusans
Golden Chalice
Royal Liqueur

Relic Interactions

Offensive SP Recovery skills benefit massively from Attack Speed buffs, or any kind of SP support as a whole. S2 can greatly capitalize on Anger of the Siracusans.

Recommended Promotion

E2 strongly recommended. Access to S3 and S2 masteries are fairly important.

Module Analysis

Operator Impact: Medium / High

Meta Use: Medium / Low

Explanation: Ch'en's Skills are her primary source of damage, so increasing Skill damage is welcome.  The biggest problems for Ch'en, however, are the high SP costs and slow on-attack charging for S3, and the mixed damage of her S2 limiting its one-shot potential. The ASPD bonus and extra damage this Module offers does take some small steps towards improving her issues, but it isn't going to be enough to change her standing in meta usage.

Base Skill Analysis

Ch'en gains her second RIIC Skill at Elite 2.

It is tied with Projekt RedGitano, and Astesia for the highest Reception Room buff in the game.

Profile

Ch'en, head of the Lungmen Guard Department's Special Inspection Unit, graduated from the Royal Victorian Guard School with superb grades and outstanding achievements. During her time with the Department, she cracked down on crime, fought violent offenders, tracked down armed fugitives, and brought down international criminals.
Now works at Rhodes Island, providing on-site tactical command.

[Originium Overview]
Ch'en has never been seen using Originium, which led many to suspect she didn't have a talent for it. Indeed, she did struggle to control her Originium ability, blasting the occasional hole in a wall, blowing files everywhere, and causing more collateral damage than might otherwise be acceptable. Using Originium for too long tires her out. After discussion with the tech staff, it was decided Ch'en lacked the necessary conduit to control her Originium power. Without one, Ch'en could never master it.

I saw her test results. The thinner the staff, the better she is at assimilation. But what's the point? Maybe if you had something shaped like a sword, it might work for her. But who would want to use it for that? A sword is for slashing! We're going to need a lot more work on this..
--Caster D

Increase Trust to 100.
Ch'en graduated from the Royal Victorian Guard School with straight A's in all mandatory subjects and glowing recommendations from her professors. After returning to Lungmen, she almost immediately joined the Guard Department.
No one knows anything about her life prior to enrolling in the L.G.D. School, and no one questions her ability, dedication, or hatred of her enemies. Police officers working with Ch'en often complained about her demeanor--too strict and too harsh. Everyone thought that this harsh character would disappear in the struggle for power, and she would soften up after being worn down by endless incidents.
Surprisingly, both crime and casualty rates have declined in the past two years, and the younger generation of officers began being promoted faster and more substantively. Ch'en was promoted and joined one of the most important teams in the Department, the Special Inspection Unit.
Members of this unit are generally not allowed to serve more than two years - to protect their lives and reduce their stress. Perhaps this position isn't suitable to serve for a long time: old inspectors' careers always seem to end with heroic sacrifice.
Ch'en did not retreat. She doesn't even know how to back down.
She became the fastest promoted officer in the history of the Lungmen police force, and also the youngest Special Inspector in the Department. Those who ridiculed her were impressed by her perseverance. After all, planning for the future is one thing. Planning every day is another.
Why was she so hard? Why live life this way? No one can could understand.
There are often small pieces of paper that have been ripped apart or angrily crumbled in Ch'en's trash bin.

Increase Trust to 150.
Of course, Ch'en is not a total workaholic.
Officers who know her say she is almost perfect. She operates efficiently, scheduling her time wisely such that she can exercise and tend to her hobbies. Every minute of her day is filled with meaningful activities.
And yet this worries her colleagues even more. It is common for her to cancel her days off and to work overtime on into the night. It's also common for a mountain of paperwork to disappear one day only for her to get called into an urgent meeting when she is about to go see a movie.
She is mechanically efficient. People naturally ask her,
'Are you stressed?'
'No reason to be.'
No one has ever gotten a different answer out of her.
Ch'en lives this way every day, always doing what she can for Lungmen and honing her skills. She is always getting better, and the sky is the limit.
But what exactly is she pursuing?
Even her friends wouldn't say they understand Ch'en. She tries to do it all.

'Your father has cut ties with you. He doesn't have anything to do with me, either, but neither of us care.
Do you want to leave?
You can, but I have something to tell you before you go.
I actually know who that old person is.
But I forget a lot of things -- like that night you and your friend had a little adventure. It's easy to forget.
It's my fault. I made an unforgivable mistake.
I will forget.
If you want to leave, I will send you to a city that is safe, rich, and stable. You would have a peaceful life there.
And you will say goodbye to everything here. The home you hate, the street you hate, the people you don't like.
It's just that you will lose your opportunity to know the truth. The facts are dangerous, and I can't have innocent people getting involved.
Angry? You're angry with me? You hate me?
Well, of course. Let me be who you hate. Hate a powerless person like me.

Here is your other choice.
You choose to stay.
From now on, I would train you. You would be free to hate me and even try to kill me, if you want.
How could you not? Of course you can. You would be a natural.
Your body and mind both belong to you. I can teach you right from wrong, and if you do well, you should work with Originium on your own.
Don't forget it, just do it.
Being able to do things right is worth the hard work. Having to fix a mistake could be fatal.
Even I don't know what is in store for us in the city. It is full of opportunity. Anything can happen.
It doesn't matter if you don't understand now, you will later.
Hey, I still remember. I remember that last thing you said.
Do you persist, or do you give up?
Choose.'

Description:
Ch'en always puts herself on the frontlines.
At first, her colleagues thought she was foolhardy, and believed themselves proven right when she paid a price for it. Once she learned to wield Chi Xiao properly, however, they began to make way for her of their own accord,
both because they do not want to get caught in the blade's wake, and because they know that when Ch'en says she can do something, she will not rest until it is done.
