Review
Please keep in mind Wuthering Waves is a skill-based game and each character has a different playstyle, difficulty level and even special tricks and combos. Wuthering Waves is also a team based game and it's only by combining both these factors to the highest level a character can reach optimal performance.
The current best Electro DPS, one of the very best Whimpering Wastes DPS with huge AoE’s;
Has access to very F2P-friendly team compositions in Flare mode - will essentially never be stranded for teammates, even for beginners. Plus, probably the single best F2P WhiWa DPS in the game;
Unison is an easy upgrade path from Flare at higher investments, able to make use of Shorekeeper and Verina really well while retaining top performance.
One of the biggest Signature to permanent weapon gaps in the game. Limited weapon alternatives aren’t good in Unison mode either. Generally just pull Hsin’s Signature if you want to get her, results will not be up to par with the rest of the meta otherwise;
Pretty underwhelming Sequences in Flare mode aside from her S6 - has standard Sequence values in Unison mode though.
Hsin is a 5-star Electro Rectifier Main DPS who plays into the Electro Flare archetype and a (sort of) brand new one, Unison. Electro Flare is one of the many Negative Statuses, and all of them have received significant attention meta-wise recently. However, Unison is a previously forgotten mechanic only Jinhsi possessed up until now, that involves your character doing 2 Outros per rotation: Unison gives one for free, and your Concerto gauge gives you the other. In the same vein as how Jinhsi plays, this creates more unique team rotations compared to the usual. With that being said, Hsin’s kit has many complex elements based on her Resonance Mode, so we’ll have to go in-depth to fully understand it.
Hsin has 3 states that she will switch between during battle throughout her rotation: Answering Form, Illumining Form, and Mechanism Dominion. In Answering Form, you build up the Forte required to switch to Illumining Form, then in that form, you build up the Forte that is required to enter Mechanism Dominion, at which point you consume said Forte to then unleash Hsin’s final Ultimate. Pretty straightforward idea.
However, we can go a bit more in-depth on the details here, based on Hsin’s resonance mode. They fundamentally change how she will rotate and what kinds of synergies she will get.
In Electro Flare mode, Hsin will perform a standard 1-2-3 team rotation like in any classic team you’ve previously played, so she’ll do her on-field rotation fully until her Outro is ready and all her key abilities have been cast. Flare mechanics work in this way:
Electro Flare stacks normally get consumed every time the instance of periodic damage it should deal is triggered. When Hsin is on the team, this is not the case. Instead, Hsin will have any extra Electro Flare stacks over the stack limit (10 at base) converted into Heart of Thunder instead of Electro Rage, to then unleash a detonation of its damage in one Skill.
Electro Flare is applied by: Her first Ultimate, Forte Skill, her Basics after her Forte Skill, and her second Forte Heavy (5 stacks each), as well as her Intro (1 stack).
Once Hsin casts her first Ultimate, she will apply 1 stack of Electro Flare to enemies who have none. If another teammate applies at least 10 Flare, Hsin stores this information and raises the Flare count up to the max instead. These effects apply to all nearby enemies until her rotation ends.
Hsin gains extra Electro DMG Bonus when another character in the team applies Electro Flare onto enemies, with an extra boost if that character is Electro Rover.
In Unison mode, Hsin rotates quite differently. Unison provides her with a free Outro once every 25s when her first Ultimate is cast, at the cost of no Concerto energy. Other mechanics include:
Hsin increases the DMG of all Unison Response characters, including herself, by stacking up a unique buff (somewhat similar to Tune Strain) called Unison Boon. This buff is given when Unison Response characters perform Intros with each other;
Hsin can entirely skip the Illumining Form state and go straight into Mechanism Dominion if she Intros again after her First Ultimate;
Hsin’s Intros are enhanced if they are triggered by another Unison character and they give Hsin 50% more ATK for 8s.
In other words, you are heavily incentivized to use Unison mode with and only with other Unison characters. To add to this, Hsin’s Outro gives 20% DMG amplification to other characters in the team than herself, but only to Electro DMG (Electro Flare mode) or Unison characters (Unison mode).
Hence, we can conclude Hsin’s rotation will have her stacking up her Forte gauges (which she can only do while she is active on the field, so Swap Cancelling is restricted) and entering Illumining Form via her Ultimate. In Unison mode, she will switch out until another Unison character can give her another Intro. In Flare mode, she will stay on field and charge up her second Forte, both things done to enter Mechanism Dominion state, at which point she can do a few Basic Attacks to consume the Forte, cast her second Forte Heavy and Ultimate, and then Outro until her next rotation starts.
You may have guessed the following when we described Unison mechanics:
Electro Flare is Hsin’s more flexible mode teammates-wise, and her most F2P-friendly.
If you want to invest into Unison, Suoming is the clear-cut best choice (and frankly the only good one), and can take Hsin’s ceiling to new heights.
And this is entirely true. Performance-wise, Hsin’s Flare teams are however still restricted to using Electro Rover and Suisui at best. Overall, Electro Rover is far from an ideal character, with low total buffing potential and a lengthy rotation, meaning they too could be replaced in the future. But for now, they are enough to make Hsin a good DPS still, and a budget-friendly one at that, able to run Buling in the 3rd slot for a nearly cost-free team composition while still retaining good enough performance to clear all endgame modes when played properly.
If you choose to upgrade to Unison through Suoming, you have a top meta team on your hands. Due to scaling off general stats, the team is perfectly able to make use of Shorekeeper and Verina. It’ll be able to clear all endgames without much trouble, with an easy rotation with plenty of room for error. Unfortunately though, the only good Unison option is Suoming. Jinhsi is technically another Unison character, but her personal damage contribution has fallen out of fashion as an old 1.x character and she gives no damage buffs to Hsin, making the team overall not recommended by a lack of strength. You’re better off using an F2P Flare team overall.
In conclusion, while Hsin has no good permanent banner weapons, with her and her Signature, you essentially have a guaranteed Flare team for her out of the box, and that makes her a great pull for beginner players. Plus, Unison is a straightforward upgrade path that leads her to the top of the meta easily. Overall, Hsin is currently a top meta DPS who will greatly help in all endgame contents, under the important condition that you pulled for her Signature.

All recommended endgame stats portray a fairly good quality endgame build as a goal to aim for on most characters. However, don’t treat this as an end-all-be-all, and more of a suggestion.
All stat recommendations are given at S0 for 5-stars, S6 for 4-stars, and free characters (unless specified otherwise), based on total stats in the in-game stat-screen with the character out of combat but also active in the party (and hence some buffs may or may not apply). Any other precision may be directly specified. If not specified, Energy Regen requirements are estimated in the character’s best team.

Gameplay and teams
Hsin’s rotation is fundamentally easy to understand: build up her Forte to cast her first Forte Heavy Attack, this unlocks her Ultimate. Then, enter Mechanism Dominion and finish it off with her second Forte Heavy Attack and Ultimate. She has two ways to achieve this, based on her Resonance Mode that changes her rotation.
Summon Hsin’s Echo freely at any point throughout her rotation.
In Electro Flare mode, Hsin will adopt a standard 1-2-3 team rotation the same way the majority of the DPS characters in the game have up until this point. To use all of her key abilities the quickest, we can execute the following rotation:
Intro
Basic 4
Heavy: Realm Protector
Ultimate: Formshift
Basic: Illumining 1 (Cancel animation on cast via Skill)
Skill: Illumining
Skill: Pillars
Basic: Pillars 1
Basic: Pillars 2 (Cancel animation endlag via Dash)
Basic: Pillars 1
Basic: Pillars 2 (Cancel animation endlag via Dash)
Basic: Pillars 1 (Cancel animation endlag via Heavy)
Heavy: Stilling All Horizons
Ultimate: Pillars Across Heaven
Outro
In Unison mode, Hsin’s team rotation concept changes to be similar to what Jinhsi used to offer in the past. Here, going by Intros and Outros as reference points, it’s more of a 1-2-3-2-3 loop, where 1 is your Support, 2 is your Unison secondary, and 3 is Hsin herself. She will indeed use 2 Intros per rotation to skip any Illumining Form attacks and go straight into Mechanism Dominion with the extra perk of retaining the maximum amount of damage buffs possible, like so:
Intro: Manifold Unison
Basic 3
Basic 4
Heavy: Realm Protector
Ultimate: Formshift
Skill: Illumining (Swap)
Outro (Unison)
—> Build up a second Outro from your Unison Secondary here.
Intro: Manifold Unison
Basic: Pillars 1
Basic: Pillars 2 (Cancel animation endlag via Dash)
Basic: Pillars 1
Basic: Pillars 2 (Cancel animation endlag via Dash)
Basic: Pillars 1 (Cancel animation endlag via Heavy)
Heavy: Stilling All Horizons
Ultimate: Pillars Across Heaven
Skill (Swap)
Outro
For the above rotation, seeing as Hsin and Suoming can rotate quickly, if you need to extend the team’s rotation, you can cast more Pillars basics up to your discretion (4 times Basic 12 should be the maximum while conserving Suoming’s Outro buff).
Hsin is a very straightforward character with very little potential for Swap Cancels. The most she could get done is casting a few Answering Form Basics before her rotation starts during another teammate’s Swap window, to immediately cast her Forte Heavy once she Intros in. However, she needs to be on-field in order for any Forte to be generated. This makes her very restricted to a nearly completely strict on-field rotation.
In Flare mode, at the end of Hsin’s last rotation in a fight, an Answering Form Skill may be cast (with Hsin staying on field) in order to consume any leftover Heart of Thunder from her last rotation. This can squeeze in some extra damage at the end of a fight for a bit of extra scoring.
Much less impactfully, you can also cast an Answering Form Skill at the very start of the fight and Swap Cancel that, for some negligible extra damage (why you don’t do this later until the very last rotation in Flare mode is because it consumes Heart of Thunder stacks even if you Swap Cancel it, highly impacting your Flare detonation damage if you do this, or your rotation time if you stay on field).
The Skills that are swapped at the end of the Unison rotation parts before the Outros are simply there for free extra damage, and can be skipped if you’re uncomfortable with fast Swap Cancels. Do them too slowly, and they stop being DPS increases.
Suoming Rover (Electro) - Hsin's best secondary options for Unison and Electro Flare respectively. Suoming gives Hsin access to her best overall team by far, since the array of buffs she can provide for Hsin are massive. Electro Rover is less capable in terms of buffs and can be more inconsistent, but overall they're more F2P-friendly and still allow Hsin to perform up to endgame standards for cheaper.The Shorekeeper 
Verina Suisui 
Chisa 
Buling - Shorekeeper is Unison Hsin's best current Support as there is no dedicated Support for Unison teams, so she comes out on top by virtue of being the best generalist choice. Verina is her F2P replacement. Suisui, Chisa and Buling are all options for Electro Flare Hsin. Suisui is generally the strongest, Chisa in the in-between, and Buling is the F2P fallback option, giving extra Flare application and Skill DMG-oriented buffs. Buling can also be used in Unison to a lesser degree than Verina.Rover (Electro) 
Jinhsi - Electro Rover is Hsin's current best second slot teammate, as they provide her with some external Electro Flare application which is great for triggering her passives, as well as being able to provide her with a massive amount of Electro DMG Bonus among some other buffs. Jinhsi is the only current Unison character in the game, so she's the only option for Unison mode Hsin to be used with normally, but generally she's not recommended even over a F2P Flare team.The Shorekeeper Suisui Chisa Buling - Shorekeeper is Unison Hsin's best current Support as there is no dedicated Support for Unison teams, so she comes out on top by virtue of being the best generalist choice. Suisui, Chisa and Buling are all options for Electro Flare Hsin. Suisui is generally the strongest, but Chisa can outperform her in Quickswap. Buling is the F2P fallback option, giving extra Flare application and Skill DMG-oriented buffs.Best Team (Unison)
Jinhsi is theoretically usable instead of Suoming here, but there's a huge performance gap and it's not recommended over an F2P Flare team.
