Possible Team Comps
Regarding Team Comps
As for this Season's boss lineup, the required elements are extremely unconventional with the possible best team comps you can make. Instead, focus on getting synergistic Blessings to circumvent the inherent weakness. At most, try to save AoE groupers like Venti or Sucrose for the Mandragora at Act 8.
If playing in Lunar Mode, It's best to save at least another grouper and a Nightsoul character for the Arcana Challenges.
Act 1 - 3
| Physical Plunge | |||
|---|---|---|---|
|
Eula
|
Electro
|
Xianyun
|
Any |
| Superconduct | |||
|
Electro
|
Cryo
|
Any | Any |
| Varesa Plunge (Boss) | |||
|
Varesa
|
Electro
|
Anemo
|
Any |
During the early stages of the Performance, choices are restricted to just Superconduct or Swirl team comps, you would want to use Eula, Mika, and other non-high priority characters as long as Varesa or Xianyun can be saved on Act 3 boss or the Lunar Arcana II challenge with Mimifloras.
Against the Jadeplume Terrorshroom, its best to use Electro to make it Activated and reduce its RES afterwards. Any teams that have Electro, either as an on-field carry or as an off-field applicator are good to have for this boss.
Act 4 - 6
| Freeze Teams | |||
|---|---|---|---|
|
Cryo
|
Furina
|
Any | Any |
| Swirl | |||
|
Anemo
|
Any | Any | Any |
| Fall DMG (Boss) | |||
|
Jean
|
Any | Any | Any |
As usual, Act 4's Monolith Defense specifically benefits from units that have taunt or AoE capabilities, but if you can, try to save Venti or Sucrose as they are needed for the Mandragora at Act 8. AoE teams are particularly amazing in this Act, but depending on the particular stage that you encounter, you'll either need Hydro or Pyro units to effectively deal with them. Choose wisely if you can afford to use such units so early.
Act 6's Veteran Battle Hardened Waveshuttler moves a lot and may Freeze and Shatter your team. You can reverse-uno the boss, trivialize, and counter it with Freeze team with the Special-Guest Star, Furina, or cheese it with Jean fall damage trick!
Act 7 - 8
| Lunar Teams (Frostnight Scion) | |||
|---|---|---|---|
|
Columbina
|
Ineffa
|
Any | Any |
| Electro Swirl Teams (Boss) | |||
|
Anemo
|
Electro
|
Any | Any |
| Pyro Swirl Teams (Boss) | |||
|
Anemo
|
Durin
|
Any | Any |
Act 7 benefits Lunar teams especially with Ineffa and the Special-Guest Columbina. If you don't have these yet, having your most powerful Anemo carry should do it.
The Act 8's Hexadecatonic Mandragora boss fight requires Anemo groupers and either Pyro or Electro to satisfy its conditions.
Act 9 - 10
| Cryo-Swirl | |||
|---|---|---|---|
|
Cryo
|
Anemo
|
Any | Any |
| Boss-Killers | |||
| Single-target DPS | Any | Any | Any |
Act 9 and 10 features single-target targets, with the Perpetual Mechanical Array headlining the last act. Any remaining coherent teams should be used on the Lunar Mode: Arcana challenges first before attempting, as there are no real element checks for these acts.
Lunar Mode: Arcana Challenges
| Swirl Teams (Challenge I) | |||
|---|---|---|---|
| AoE DPS |
Anemo
|
Any | Any |
| Natlan Teams (Challenge II) | |||
| Natlan Character | Natlan Character | Any | Any |
The first Arcana Challenge for this season features waves of Eremites. AoE teams are best to use here to defeat all of them at once and hasten the clock.
The second Arcana Challenge features Tenebrous Mimifloras, as such, saving any Natlan units are best to use here.
Best Characters to Use
| Act 3 | |||
|---|---|---|---|

|
Varesa

|

|
All characters, including the opening characters and guest stars, will still be selected at random.
However, above is a list of example team comps for characters to use for each Act's boss fight.
Durin, Bennett, Columbina, and Furina are the characters who can save your run so it's best to save them on the bosses and Arcana challenges, especially the Lunar Team with Flins, Ineffa, Columbina, to finish off the latter stages.
Season 21 Act 1 - 3 Guide
Pre-Boss Priorities (Act 1 - 2)
 Pick 1 or 2 Electro/Anemo blessings to buff Varesa teams later on. |
| Use Eula teams for Acts 1 and 2, or Varesa if you're stuck in a pinch. |
| Save at least 1 Energy from Varesa for the boss. |
With the Opening Characters, your priority is to check and see which of these units you plan to bring into the later levels, and consume the energy of the ones more suited for fodder opponents. The important to save these Acts is Varesa, as she's the strongest starting character.
With the rest of your currency, you can opt to purchase blessings to enhance Electro or Anemo right off the bat or later on, especially if you have a lot of carries for that element.
General Strategy (Act 1 - 2)
Use Physical Teams, Only Use Varesa if Needed
As you will likely struggle to pick a comfortable team comp in this starting lineup, expend Eula and her teams to make up a Physical-core.
If you can't clear at all, Varesa is there to carry you, but as advised earlier, it's best to save her for Jadeplume Terrorshroom.
Act 3 Climactic Showdown
 Jadeplume Terrorshroom
|
Defeat the Opponent Within 70s
In Act 3's boss fight, apply Electro to fill up the bar and make it Activated. When activated, the boss will become more dangerous. Avoid its attacks until it runs out of steam and becomes RES downed. Of the available picks, Varesa with Swirl buffs and Xianyun should be able to defeat it with ease.
Season 21 Act 4 - 6 Guide
Pre-Boss Priorities (Act 4 - 5)
| Spend points on Companion events, inviting most of your Characters (especially Anemo for Monolith). |
| Spend the remainder of your points to get any chosen Blessings. The Anemo blessings are amazing for Act 6. |
| If you have Furina or Columbina, use a Freeze team against the mobile Battle-Hardened Waveshuttler boss. |
Upon reaching Act 4, you will have lost a portion of your opening characters and may have one or two uses left for the rest, so start unlocking your more powerful personal units, especially Cryo and Anemo units for later stages
Act 4 Strategy
Choose Your Monolith Defense Wisely
Act 4 is the Monolith Defense which is best for groupers like Venti, but he's also important for the Mandragora later so try to save at least one use for characters like him later on.
Characters who Taunt like Ororon, are also great to have if you don't want to use your Anemo groupers early.
Act 5 Strategy
Use any Fodder units as you can
Act 5 can depend on the matchup but as long as you defeat the required number of enemies, any team comp will do, especially those who are weaker in your team.
Act 6 Climactic Showdown
 Koholasaurus Warrior: Waveshuttler
|
Defeat the Opponent Within 80s
The Veteran Waveshuttler enemy in Act 6 is very mobile and attacks with Hydro and Cryo, making you susceptible with Freeze. To counter it, Freeze or crowd-controls from Anemo units are generally the way to go to prevent it from surfing around the battlefield.
As the boss can also be staggered, using Jean to initiate Fall DMG is also good to use.
When the boss spawns a Cryo device, if you have Bennett or Durin, they will be able to handle it with ease.
Season 21 Act 7 - 8 Guide
Pre-Boss Priorities (Act 7 and Act 8)
| Have a Lunar team for Act 7, or choose your stronger Cryo, Electro, or Anemo hypercarry teams. |
| If you haven't still, choose one grouper like Sucrose for the Climactic Showdown. |
| Hold Bennett as much as you can for Act 8. |
| Spend your blessings on Anemo blessings. |
Around this time, you can start to unlock more of your blessings in preparation for Act 8's boss fight. Act 7 is a particularly hard floor to complete due to the Lunar horse, so having Columbina may save your run if you have her.
Act 7 Strategy
This act is made easier with Lunar teams to counter the Lunar horse. If you don't have at least Columbina, expending a use for one of your stronger teams are pretty much a necessity to complete this act. Note that the Electro horse is immune to Electro, and Cryo to itself.
Act 8 Climactic Showdown
 Hexadecatonic Mandragora
|
Defeat the Opponent Within 75s
The boss works the same as the overworld variant. It starts with a high resistance and requires either Pyro or Electro to fill its gauge.
Once its been filled up, the boss will explode into multiple mini-mandragoras. Use your groupers here like Sucrose and defeat all the mini-mandragoras to drastically reduce its resistances!
Lunar Mode: Arcana Challenges Guide
Arcana Challenge I
 Eremite - Stone Enchanter
|
 Eremite - Desert Clearwater
|
 Eremite - Scorching Loremaster
|
 Eremite - Daythunder
|
Note: If you're in Lunar Mode, you must do the Arcana Challenges before Act 10 as otherwise it will end the performance.
Arcana Challenge I Strategy
Bring Your AoE Team
For this challenge, waves of Eremites will spawn. As some of these Eremites also spawn their minions, and to ensure you satisfy the requirement until the countdown ends, use your AoE teams like Venti Swirl or Flins Lunar-Charged to defeat all of them at once!
It's also great to bring a shielder like Ineffa here as enemy hits might stagger or even kill your characters.
Arcana Challenge II
 Tenebrous Mimiflora
(Iktomisaurus Warrior, Tepetlisaurus Warrior, Qucusaurus Warrior) |
Arcana Challenge II Strategy
Bring Natlan Teams
if you still have your Varesa in your team, she can already fill the requirement for these waves of enemies. If not, other Anemo or Electro Natlan characters like Chasca, Ifa, or Ororon will help you fill up the gauge!
Otherwise, you can use characters with high elemental application like Swirl to remove its Nightsoul shield.
Season 21 Act 9 - 10 Guide
Pre-Boss Priorities (Act 9 and Act 10)
| Leave your best damage dealers for Act 10 and Arcana Challenge. |
| Use Single-target DPS units for Act 9. |
| Spend the remainder of your points on the more beneficial Blessing upgrades or Mystery Caches buffs that increase DPS, especially Electro-related buffs. |
By this point in time, you should have enough energy to use up your last spare DPS units for Act 9's bounty units, and your main Geo DPS for Act 10's final boss.
If you have the spare currency, you can use them on mystery caches to try and get some units back.
Act 9 Strategy
Focus Down the Bounty Units
Similar to previous seasons, Act 9 requires you to kill certain Bounty units that spawn alongside a never-ending wave of enemies until you complete the challenge.
As a trick, swirling the Pyro Slimes to the enemy for a Cryo DPS to trigger Melt will make your DPS soar higher!
Act 10 Climactic Showdown
 Perpetual Mechanical Array
|
Defeat the Opponent Within 75s
The final act boss in act 10 is the Perpetual Mechanical Array, which has no real gimmicks other than focus-firing the boss, so any of your strongest remaining team members can focus on dishing out as much as damage as you can.
When it reaches the invulnerability phase, focus on the mob that glows up, as defeating that automaton will remove the boss' invulnerability shield.

Whoever signed off on the Act 7 target for 6.4 is the biggest piece of shit imaginable. Completely impossible if you lack Bina and/or Furina. Even with them it sucks because Lunar-reactions are a buggy mess, so I guess you NEED Ineffa or Flins as a random electro unit won't cut it.
