Floor 12 Chamber Information

Chamber 1 First Half

Wave 1	Wave 2
Assault Specialist Mek x1	Perpetual Mechanical Array x1

You need to take out the Mek quickly to buy more time for the Perpetual Mechanical Array.

It is a wise choice to lower the Array to about 20% HP to trigger phase two, and then target the glowing spawned mech to kill it and remove the boss's invulnerability.

 

Chamber 1 Second Half

Wave 1	Wave 2
Wind Operative x1	Radiant Moonfly x1

The Wind Operative is really annoying, so if you're running Freeze, pin it in place to stop its jumps or apply Bond of Life to your party to mitigate its harassment.

Against the Radiant Moonfly, watch for its Radiant Cocoon debuff, which lowers your CRIT and damage. Remove it by healing characters back to full HP or by perfectly i-framing the Cocoon attack, though the latter requires precise timing.

 

Chamber 2 First Half

Gluttonous Yumkasaur Mountain King x1

For this half, you'll only face the Yumkasaur Mountain King. As usual, hit the Pomegranates with Pyro when they appear to stun it and deal significant damage. Then watch out for its spin attack, especially when using Bennett, as it can trigger Burning on your character.

 

Chamber 2 Second Half

Wave 1	Wave 2
Oprichniki Thunderblitz Gvardiya x1	Hiljetta x1

Quickly eliminate the fodder Oprichniki elites to free up time for dealing with Hiljetta, the Battle-Hardened Elite Treasure Hoarder. Since she is lightweight, she can be lifted by Anemo crowd control abilities from characters like Venti or Jean.

At a certain point, Hiljetta will enter a charging state, during which she attempts to absorb devices that spawn nearby. To prevent this, trigger either Freeze or Overloaded on her immediately. If she successfully absorbs the devices, her attacks will become empowered and can easily defeat your active character unless you are able to consistently dodge them.

Successfully interrupting this absorption process will also deal damage to Hiljetta by shattering her.

 

Chamber 3 First Half

Wave 1

Radiant Glacial Wolf

The Radiant Glacial Wolf behaves identically to its Overworld Valiant Chronicles counterpart, summoning a Cryo-shielded clone of itself. This shield is immune to direct Pyro or Electro damage and can only be broken through Pyro-Swirl or Electro-Swirl reactions. To remove it, have an Anemo character Swirl a Pyro or Electro aura onto the clone. Doing so will shatter the shield and stun the Glacial Wolf.

 

Chamber 3 Second Half

Secret Source Automaton: Overseer Device x1

The Secret Source Automaton Overseer Device opens the fight in its laser phase, during which it has high resistance to all elements. To neutralize this, apply Cryo attacks consistently to fill its gauge. Once the gauge is full, its resistances drop and the lasers cease.

Constant Cryo application is essential throughout the encounter. Bringing two Cryo characters—such as Skirk, Wriothesley, Escoffier, Kaeya, Rosaria, Layla, or Charlotte—will render the boss largely helpless for most of the fight, leaving its massive health pool as your only real challenge.

 

Floor 12 Recommended Teams

First Half

For the first half, although the Abyss Blessing favors Anemo, Pyro is still essential for dealing with the Yumkasaur Mountain King and the Radiant Glacial Wolf's mechanics. The Glacial Wolf, in particular, requires Pyro-Swirl or Electro-Swirl to break its shield—meaning you'll need an Anemo character capable of infusing or swirling Pyro or Electro.

Your options are either to run a Swirl-Pyro or Swirl-Electro team from Varka's lineup, or to bring a standard Pyro team with a Swirl enabler like Kazuha.

Teams
Venti	Durin	Bennett	Faruzan
Venti	Durin	Bennett	Varka
Sucrose	Bennett	Varka	Mavuika
Mavuika	Kaedehara Kazuha	Bennett	Xilonen

 

Second Half

In the second half, This floor heavily favors Cryo and Freeze teams because of the Elite Treasure Hoarder and the Secret Source Automaton. Skip Pyro units—the Radiant Moonfly is very resistant to it.

Bring a healer too. The Radiant Moonfly's Cocoon effect lowers your CRIT Rate unless you're at max HP, so you'll need consistent healing to counter it.

Teams
Skirk	Escoffier	Furina	Shenhe
Wriothesley	Escoffier	Furina	Shenhe
Wriothesley	Escoffier	Furina	Citlali
Varka	Venti	Escoffier	Citlali
