Special Guests Only Available if You Have the Character

Aside from the Opening Characters, you can invite the 4 Special Guests Ineffa, Yae Miko, Thoma, and Chiori for this season.

Take note that these characters are only available if you personally have them, but you can always borrow someone else's Special Guest if you so desire using the Supporting Cast system.

Recommended Alternate and Supporting Cast Characters

Support

Make Sure Your Supporting Cast is Cryo, Hydro, and Anemo

Aside from the Special Guests, the only characters available in this season are Cryo, Hydro, and Anemo characters. Be sure to choose these as your Supporting Cast for other players to use!

If you are in need of another player's built characters to give your team that much-required edge in the Theater grounds, consult our request board below!

Possible Team Comps

Regarding Team Comps

Based on the boss lineup for this season, you will want to start with Hydro-core teams before transitioning slowly to Stellar-Swirl teams.

Afterwards, start shifting towards Cryo and Anemo teams when you already reach Act 6, since it requires Stellar Glimmer reactions and Cryo from here on out, and you will only have access to Stellar-Conduct through Ineffa.

Act 1 - 3

Any
Any	Any	Any	Any
Hydro Core (Boss)
Hydro	Hydro	Any	Any

The first two acts can be done with the opening characters that is available, but do try to save your best Cryo characters until Act 6 or so.

The Perpetual Mechanical Array is weak to every element in your roster, so pick and choose your best damage dealers to break through it.

Act 4 - 6

Anemo-core (Monolith)
Anemo	Anemo	Any	Any
Stellar Glimmer (Boss)
Cryo	Anemo	Any	Any

Act 4's Monolith Defense can be done with any type of team with slight preference with Anemo-based reactions to group up enemies.

Furiosa serves as the boss for Act 6, and necessitates the use of Stellar-Glimmer teams to disable her rooting mechanic.

Act 7 - 8

Cryo core
Cryo	Cryo	Any	Any
Stellar Glimmer (Boss)
Cryo	Anemo	Any	Any

Act 7 can be done with any team, depending on the enemy options that you see with slight lean with Cryo teams. Regardless, adjust accordingly to opponents you might encounter.

Act 8's Chimeric Winged Lion also wants Stellar-Glimmer teams to be used against it, or Cryo-centric teams in particular.

Act 9 - 10

Hydro Swirl
Hydro	Anemo	Any	Any
Freeze (Boss)
Cryo	Hydro	Any	Any

Similar to Act 7, it really depends on what enemies you encounter, but most will be weak to either Hydro or Anemo, so lean towards Hydro Swirl teams to go through this.

Act 10 features the Secret Source Automaton: Overseer Device, which wants multiple Cryo units to burn through its Flow Momentum generation.

Lunar Mode: Arcana Challenges

(Challenge I) Teams
Healer	Any	Any	Any
(Challenge II) Shielder
Bow User	Shielder	Any	Any

The first Arcana Challenge for this season features waves of Rockfond Rifthounds that will chew through your team's HP. Bring a healer to counteract this.

The second Arcana Challenge features different Ruin machine opponents that will require you to outlast them. A Bow unit is recommended to bring down any Ruin Drakes in the sky, and shielders are recommended to prevent interruption.

Best Characters to Use

Act 3
Neuvillette	Furina	Prune	Thoma
Act 6
Vesna	Faruzan	Traveler (Cryo)	Qiqi
Act 8
Sandrone	Yae Miko	Qiqi	Odette
Act 10
Skirk	Escoffier	Furina	Vodyanitsa
Lunar Mode: Arcana Challenge (I)
Wriothesley	Columbina	Vodyanitsa	Ineffa
Lunar Mode: Arcana Challenge (II)
Sandrone	Columbina	Odette	Ineffa

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.

Some characters are reused, assuming you don't use them elsewhere.

Season 28 Act 1 - 3 Guide

Pre-Boss Priorities (Act 1 - 2)

Build up blessings favoring Stellar Glimmer for boss stages.

Use Hydro teams for the early acts.

Save your best Cryo characters for Acts 6 and above.

Invest on Anemo and Cryo Blessings for the later stages early on. The opening characters are sufficient should be sufficient enough to clear Acts 1-3 as it's generally very easy.

Save your Cryo characters for 6, as best as you could as Stellar-Glimmer is the main focus team for this theater.

General Strategy (Act 1 - 2)

Use Hydro Core Teams

As usual, try not to use your strongest characters yet. Any sort of Hydro Swirl team should be viable, as long as you get the necessary blessings for later.

You can get some blessings for Hydro and Anemo combinations, but don't invest too much since you'll want to put more into late game.

Act 3 Climactic Showdown

Perpetual Mechanical Array

Use Any Strong DPS Team

The Perpetual Mechanical Array is weak to any element in your party, giving you more options on what team to bring or create. Focus on using your best available DPS for this fight to clear it in time.

Season 28 Act 4 - 6 Guide

Pre-Boss Priorities (Act 4 - 5)

Spend more points to increase your character lineup.

Start shifting towards Stellar Glimmer blessings in preparation for Act 6 and onwards.

Save your Cryo and Anemo Characters for Act 6 and 8.

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

Recommended to Choose the Fatui Monolith

Act 4 is the Monolith Defense, you can use taunters like Lynette to stop the Fatui units from targeting the Monolith. You will also have access to ample grouping options so you can keep them away.

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

Furiosa

Destroy The Roots and Reposition Often

Furiosa's entire moveset is based around her root generation. Focus fire on these everything she brings them up as it will disable whatever move she was planning, and give you a safer means to attack them.

It is also recommended to move around a lot to dodge Furiosa's Arrow Shower if she can get it off.

Season 28 Act 7 - 8 Guide

Pre-Boss Priorities (Act 7 and Act 8)

Prioritize Stellar Glimmer blessings and teams for Act 7 onwards.

Add more characters to your lineup if needed.

If you can afford, try to have Freeze blessings in case you need it.

Around this time, you can proceed to add more blessings or characters for Stellar Glimmer teams for the Act 8's boss.

Act 7 Strategy

Similar to Act 5, Act 7 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 8 Climactic Showdown

Chimeric Winged Lion

Break Through Its Electro Shield

The Chimeric Winged Lion spawns in an enhanced shielded state, represented by the Electro shield. Stellar Glimmer damage can chunk through this shield faster, making it your recommended way to deal with this phase.

Once the shield is off, the Winged Lion will be immobile for a time, then fly around the battlefield upon recovering. However, it will no longer have the Electro shield, allowing you to chip it down with your attacks.

Lunar Mode: Arcana Challenges Guide

Arcana Challenge I

Rockfond Rifthound

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 a Healer for the Stage Mechanics

The stage will periodically deal damage to your active character. It's highly advisable that you bring a healer to counteract this, preferably ones that can heal the entire team.

Try to focus down each Rifthound one at a time since even one kill can lower the time limit.

Arcana Challenge II

Ruin Grader	Ruin Guard
Ruin Drake - Skywatch	Ruin Drake - Earthguard

Arcana Challenge II Strategy

Bow and Shield Users Are Good

Due to the presence of the Ruin machines on this level, you can also try to kill off as many as you can to reduce the time remaining, but make sure you have ample Shielding or Healing to live through their heavy attacks.

A Bow unit is recommended specifically to hit the Ruin machines in their weak spots, specifically towards the Skywatch Ruin Drake.

Season 28 Act 9 - 10 Guide

Pre-Boss Priorities (Act 9 and Act 10)

Leave your best damage dealers for Act 10 and Arcana Challenge.

Save Cryo Units on Act 10.

Spend the remainder of your points on the more beneficial Blessing upgrades or Mystery Caches buffs that increase DPS.

If you still haven't cleared Arcana Challenge, we recommend doing it now to get more characters and blessings to make Act 9 and 10 much easier.

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.

From what we have tested, you can either encounter Wildwood Leshies from Snezhnaya, or Avatars of Lava from Natlan. We recommend the Avatars of Lava if you still have a good amount of Hydro units left, and the Wildwood Leshies otherwise.

Act 10 Climactic Showdown

Secret Source Automaton: Overseer Device

Bring Ample Cryo Units

This entire fight is based on whether or not you can counter the Overseer Device's Sweeper Mode by interrupting its Flow Momentum with consistent Cryo application.

Doing so will lower the RES of the Overseer Device and allow you to properly damage and eventually defeat it.
