The "trio" team is the term used to refer to a specific team lineup, that being the
Herrscher Of Finality / Herrscher Of Truth / Herrscher Of Origin.
When all three of them are in the same team they gain unique mechanics and skill changes that enable them to form a tight synergy and form a "double dps" team composition with Bronya supporting the other two.
As you may have noticed all three of them are Imaginary type DPS, giving them high performance on IMG type enemies, as well as SSS Benares. due to their very high raw damage output they are capable of trivializing (and stealing) weathers that were not meant for them in the first place.
Additionally They form the perfect team to tackle the new [Symphonic Environment]

As you can see, this weather is designed for them to perform very well.
With a single element in the team enemies will take 20% more elemental damage
With two elements in the team, 30%
With three elements in the team they will take 50% more elemental damage, a huge spike!

Mechanics
This is the section that will go over different changes in the Trio core kit that comes into play specifically for this team, as we went over at the start many skills are buffed, changed, and enhanced when they are in this particular team.
⭐Leader Skills

[Herrscher of Finality]: boosts the teams All elemental damage by 35/40/45% (S0/S3/SS3) If Mei is on the team this effect is increased for the both of them by an additional 35/40/45% (S0/S3/SS3)
[Herrscher of Origin]: Boosts the teams Elemental damage by 24/27/30% ( S0/S3/SS3) and grants them 35/40/45 (S0/S3/SS3) Initial SP, If Kiana is on the team they will both gain an additional 35/40/45 (S0/S3/SS3) Initial SP.
Generally, you will be using Finality as the leader for Abyss, and Origin as the leader for Memorial Arena.
This is because the SP start doesn't do anything for you in Abyss, while providing a large boost in Memorial Arena.

⭐Joint Bursting

Narrative of Infinite Truth
In the trio team, [Herrscher of Truth]'s ultimate is replaced with [Joint Bursting] deals Ice DMG, removes the switch CD of [Herrscher of Finality], then activate her [Special QTE] attack.
SP Cost reduced to 75.
Cooldown reduced to 15 (cannot be affected by cooldown reduction effects)

Bronya triggering joint bursting

In the trio team, Mei's ultimate is replaced with [Joint Bursting] deals Lightning DMG, removes the switch CD of [Herrscher of Finality], then activate her special QTE attack.
SP cost reduced to 50.
Cooldown reduced to 15 (cannot be affected by cooldown reduction effects)

Mei triggering Joint bursting

Kiana's special ATK passive
If [Herrscher of Truth]'s [Joint Burst] hits the enemy they will take 6.9% more total damage.
If [Herrscher of Origin]'s [Joint Burst] hits She recovers 13 SP.
After entry through [Joint Bursting] the character will deal 13.1% more total damage.

⭐Joint Ultimate

[Herrscher of Finality] ultimate is boosted with [Herrscher of Truth] and [Herrscher of Origin] present in the team.
[Time Wave] will no longer be removed upon switching characters.
Her ultimate will be enhanced and replaced by [Joint Burst] dealing more fire damage, but additionally lightning and ice damage.
This can still directly damage the core.


When [Herrscher of Finality] enters through [Joint Bursting] she deals Fire DMG and stacks 5 "Descent".
Entry through [Herrscher of Truth] Joint bursting can be connected into Basic ATK sequence 3.
⭐Passives

Kiana's ultimate passive
When both [Herrscher of Truth] and [Herrscher of Origin] are in the team, the entire team will gain 15% elemental damage.

Mei's ultimate passive
[Joint Bursting] makes all enemies take 8.3% more Total DMG for 10s.
When [Herrscher of Finality] and [Herrscher of Truth] are on the team, casting [Malice Expunged] makes them deal 8.3% more Total DMG for 10s.

Mei's Basic ATK passive
When [Herrscher of Finality] and [Herrscher of truth] are present in the team, Mei will deal 50% more Total DMG within 10s of [QTE entry]; triggering it again refreshes the duration.

Kiana's combo passive
With [Herrscher] of Origin and [Herrscher of Truth] on the team.
[Moon Blade Stance]: Combo ATK deals bonus fire and lightning damage.

Kiana SSS passive
Total damage +10%
All enemies take more damage from Mei and [Herrscher of Finality].

How to Rotate
Since that's out of the way it's time to get into an example of how you would be rotating..
⭐Opening Rotation

ty to my friend the great nonovana for making me this
- Swap to Bronya, use her weapon active -> attack once to connect into the 4th basic attack sequence for additional SP.
- Enter her "mech mode" by tapping ult, this can be done during the animation of her 4th basic attack.
- Use her combo ( skip on first rotation ) then her Joint burst ( ultimate ) to trigger Kiana's Special QTE
- Use Kiana weapon active, then combo attack to trigger Mei's QTE
- Use Mei weapon active -> Evade when it flashes-> Attack -> Hold ATK to Combo attack
- Use Mei Joint Burst (ultimate) to trigger Kiana special QTE, then use weapon attack -> combo attack -> hold evade.
- Use Kiana's weapon active -> full basic attack sequence until you start to use combo attack -> hold ultimate to trigger it as soon as you can.
If you don't have timestop, instead you would just DPS with Kiana until it's time to start the next rotation when Bronya's buff falls off.
⭐Follow up Rotation

- Swap to Bronya, use her weapon active -> attack once to connect into the 4th basic attack sequence for additional SP.
- Enter her "mech mode" by tapping ult, this can be done during the animation of her 4th basic attack.
- Use her combo attack then her Joint burst ( ultimate ) to trigger Kiana's Special QTE
- Attack on Kiana into Kiana weapon active, then combo attack to trigger Mei's QTE
- Use Mei weapon active -> Evade when it flashes-> Attack -> Hold ATK to Combo attack
- Use Mei Joint Burst (ultimate) to trigger Kiana special QTE, then use weapon attack -> combo attack
- Joint Ultimate
From there you would look to use "Opening Rotation" with the addition of Bronya's Mech mode combo attack!

Weapon Comparisons
This will not be doing in depth rundowns on the weapons or why they work as well (or as poorly) as they do, but will instead jump right into the tests themselves.
For more information on the weapons please refer to the "Weapon Test" Section of the following links. Origin Finality

⭐Herrscher of Finality: Weapon
[Domain of Genesis]- 614,268 DPS (100%)
[Domain of Incandescence]- 411,772 DPS (67%)

⭐Herrscher of Origin: Weapon
[Domain of Unity] - 614,268 (100%)

For the video, please refer to the "[Herrscher of Finality]" Weapon section.

[7 Thunders]- 460,386 (74.9%)
⭐Herrscher of Truth: Weapon
[Domain of Ascension] - 614,268 (100%)

For the video, please refer to the "[Herrscher of Finality]" Weapons

[C- Bunny 19] - 480,870 (78%)
For this one pay special attention to "DPS" and the battle duration

Stigmata
To ensure proper testing all ATK affixes will remain the same throughout this test.
Keep in mind this is not flawless, it is a fixed rotation on a stationary target, it does not directly portray performance.
This will not be doing in depth rundowns on the Stigmata or why they work as well (or as poorly) as they do, but will instead jump right into the tests themselves.
Instead of being a damage test over a single rotation, it will be a DPS test across 3 rotations.
due to that instead of doing many tests I will instead redirect you to my guides specific to the character that did more in depth testing on stigmata, but across a single rotation.
For more information on the Stigmata please refer to the "Stigmata Comparison" Section provided -> Origin Finality

⭐Herrscher of Finality: Stigmata
[Kiana TMB]- 614,268 DPS (100%)
[Lee TB + Thales M] - 485,653 DPS - (79%)
Keep in mind that if you ever have SP issues the DPS will drop, especially on longer rotations. For more information check the link provided at the start of the Stigmata section.

⭐Support Hofi with Turg?
Now hear me out, I know you are probably looking at me with a look reflecting you think I've lost it.
I know you want to ask "why would you suddenly slam support gear on the supposed to be DPS of the team, and why use this over HoO + GD + HTR? But the thing is this actually works quite well as a cheap option with the potential to perform closely due to a few factors that should be kept in mind.
- This lowers the cost of Mei's ultimate from 75 to 50, and Bronya's ultimate from 125 to 75.
- Using her as a leader enables you to gain an extra 35/40/45% + 35/40/45% Elemental damage (S0 /S3/SS3)
- Turg isn't being used in the team so this technically allows her to keep her own damage up + the others.
- Herrscher of Truth's Joint Burst hits the enemy they will take 6.9% more total damage
- Herrscher of Finality and Herrscher of truth are present Mei will deal 50% more Total DMG within 10s of QTE entry
- The entire team will gain 15% elemental damage
So all and all, this will enable you to run Trio on the likes of Kevin and Benares if you are missing Kiana's full gear.
Not saying that her gear isn't worth picking up, more so that you don't need to feel crippled if you don't have it, and this remains a potent option.
[Turg TB Tesla M] - 589,744 (96%)
[Turg TB Pool Mei M] - 579,329 (94%)
I have also checked this with other various support sets, none of them have performance worth writing home about besides Turg.
As you can see it has really respectable DPS, for the middle piece you would use...
- Tesla Band M - This gives me the best results on DPS dummy, Kiana isn't dealing enough damage and Pool party doesn't have a long enough duration to enhance Mei.
- Mei Pool Party M - Can possibly perform better on Symphony weather where her damage matters more.
- Paganini M- If you ever run into any enemies that have pesky shields.
As for if you have S0 you will lose some DPS due to needing to do a different rotation, since you cannot use her evasion skill again, but it's not like this becomes impossible.
Since your evasion skill is still on cooldown, you would do something like this.
(I chose to emulate S0 HoO by not using the evasion skill)
⭐Herrscher of Origin: Stigmata
Keep in mind, in Symphony weathers where Mei is expected to deal alot of damage too her performance will drop significantly using anything that's not her full gear.
[Raiden Mei]- 614,268 (100%)

Please refer to the video under "Herrscher of Finality Stigmata" if you would like to see the video!
[Aslaug TMB] - 483,837 (78,7%)
[Turg TB + Aslaug M]- 509,242 (82.9%)

⭐Herrscher of Truth: Stigmata
[Bronya Zachik] - 614,268 (100%)

Please refer to "Herrscher of Finality Stigmata" for the video on the performance of the full team.
[Turg TB + Aslaug M] 539,545 DPS (87.8%)
[Margrave]- 444,471 (72%)
(dont use this)
Since her Ult cost is reduced, this set is actually horrible on her.
[Aslaug]- 486,219 (79.1%)
[Gluttony T + Aslaug M + Cezanne B] 479,242 (78%)
Due to the long rotation, this set doesn't actually perform that well.
[Gluttony T+ Fu Hua Musician MB]- 453,964 (73.4%)
She can not trigger [Jin Shengtan] TM + Newton B / Pool Party M off field.
Turg works specifically because it says that the duration can be extended by summons via the 2 piece, and it's not triggering the rotation but extending the already existing rotation.

⭐Overall Stigmata Ranking
Finality

Expect some loss in performance at S0 HoO, from 96% to around 90%
Keep in mind, Turg effectively lowers [Herrscher of Finality] DPS in exchange for boosting [Herrscher of Origin] DPS.
This means it will not perform as close to [Kiana Kaslana] stigmata against say... [Symphony] weather where you need to balance the teams damage out more since they all play a part.
It could also change if you need to do more, or less rotations but I thought 3 was good.

Origin

Just like with [Herrscher of Finality] Expect different results if you are fighting against [Symphony] weather, where losing her personal damage will change the results for the worse.
This could also change if you need to do more or less rotations of course.

Truth


Rank Up Tests: Trio
A rank up damage comparison will be added later for your convenience, just know that the trio team is extremely powerful and does not require any ranks to function properly as a team, that being said there are some ranks that are better than others!
⭐Origins Rank Review
If you would like to see specifically what her rankups give and a better representation of how they enhance her in her own team please check Origin Guide
Alright so, S0 to S2 in Trio only increased the damage by roughly 270k per rotation, this is because Mei isn't doing a large amount of the damage in the team so it's diluted, S0 to S2 is better when she's making a large contribution to the overall teams damage such as in her own DPS team, or if running Turg on Kiana.
S3 is strong for Memorial Arena, it gives you 10 more SP for Kiana and Mei when Mei is used as the leader.
SS - This increased the Trio team Damage from 13.36 million to 13.6 million
SS1 - This only increased her own personal DPS, not a noticeable DPS increase. (Literally 13.6 million again)
SS2 - The debuff is welcomed, but not a massive upgrade, Increasing to 1.3775 million
SS3 - is strong for Memorial Arena, it gives you 10 more SP for Kiana and Mei, no noticeable DPS increase.
SSS - Increased damage from 13.775 million to 14.4 million, this is the largest team enhancement from all of Mei's rankups.

⭐Finality Rank up
If you would like to see specifically what her rankups give and a better representation of how they enhance her in her own team please check Finality Guide
S1 - This increased the damage from 14.4 million per rotation to 14.7 million damage,
S2 - This increased the damage per rotation from 14.7 to 15.4 million
S3 - This increased the damage from 15.4 to 15.8 million
SS -This increased the damage from 15.8 to 16.8 million
SS1 - Increased the damage from 16.8 to 17.0 million
SS2 - Increased the damage from 17.0 to 17.5 million
SS3 - Increased the damage from 17.5 to 18.0 million
SSS - Increased the damage from from 18 million to 19.3 million
⭐Truth Rank up
Because of her deal on Expansion, I am considering her default rank S2 so I had her for all the tests, this will mainly be for checking her breakpoints at SS and SSS since the ranks in between don't actually do anything in terms of supporting.
For those of you who wanted to know the difference between S0 and S2 however... I was dealing 1.3 million damage on a single attack while my friend who helped me test was dealing 1.24 million damage.
S2 - 19.3 Million damage
SS - 19.92 Million damage
SSS - 19.96 Million damage

Gameplay
This gameplay is not indicative of the maximum potential rotation, it is just for fun to showcase their unique playstyle on my favorite stages, all stats will remain the same throughout the video.



Closing + 6.4 Pull priority
That's it, this Guide actually took alot longer to make than I'd of liked it to. I hope it manages to help some people, feel free to ask any questions you may have.
in terms of priority if you are looking to optimize your pulls and gain the Trio.
I would recommend you to pick up [Herrscher of Origin] first because she's discounted, then [Herrscher of Truth]
As for why.
- Herrscher of Origin - Discounted, strong Lightning IMG dps, will only cost you on average around 40~ pulls to fullgear!
- Herrscher of Truth - She performs quite well as an Ice DPS, while also being the best in slot fire and lightning support. This effectively consolidates three roles into one character which gives her high value, not to mention the Trio doesn't work without her. She beats AE and Fischl by a fairly large margin as well. Totally worth the upgrade!
- Kiana Kaslana ELF - Considering on average she will only cost 15k crystals to get to 3* and she provides a large impact in the teams overall DPS while providing switch CD and massive grouping, it's a no brainer why she makes the cut. She also helps every Lightning and Fire team you may have.
- Herrscher of Finality - don't get me wrong, she is not "weak" or "bad" she's extremely strong, she's just not a high priority to ascertain due to various aspects such as large deals or pre-existing requirements to make the team actually work. Very strong fire DPS, very strong DPS in trio. Getting her without the pre-requisites could just be actively harmful.
A quick analogy for those confused about why the ELF ranks higher than she does.
It costs on average 92 pulls to get full gear ( 25,760 crystals ) and you will on average gain around a 15-20% raw DPS increase over alternatives for that one team with that one character. Comparatively you will spend on average 15,000 crystals to get fully geared ELF and gain that same DPS increase but for every fire and lightning team you have.
That being said, if you are a new player you won't have other teams that can benefit from said ELF and in that case Hofi would be a higher priority than the ELF.
I know this means you will most likely have to give up Finality for now, and with her being the fan-favorite I know that's not what many would want to hear, but since she has a reliance on [Herrscher of Truth] ( and often Origin ) If you are looking to optimize you will save a large quantity of pulls if you do so this way.
I wish you luck on your pulls! See you next time!
