Spiral Abyss Floor 12 Guide and Best Characters in Genshin Impact

• First Half: Characters' Stellar Glimmer reaction DMG increased by 75%.
• Second Half: All party members gain a 75% Cryo DMG Bonus.

The first and only wave features a single Battle-Hardened Chimeric Volkodlak Archer, better known as Furiosa, a Local Legend in Snezhnaya. Furiosa's core mechanic involves summoning Hindering Roots. The first attack summons 2 roots while Furiosa fires a rain of arrows. You can destroy the roots to interrupt her attacks. The second attack occurs when she burrows underground and generates a Hindering Root where she will emerge next. If you manage to attack the root before she appears again, she will be stunned for a few seconds. Aside from off-field characters that can deal damage, ranged characters or characters with fast movement speed are the best options for focusing on these roots.

The first wave features Iniquitous Baptist - Caller of Flood, Flame, and Fulmination, while the second wave features Shadowy Husk: Standard Bearer and Shadowy Husk: Defender. Iniquitous Baptist is a boss that can create multiple elemental shields in a row. For this type, it will create Electro > Pyro > Hydro shields in order. You need to use the appropriate elements to destroy these shields and stun the boss for a few seconds. Once all 3 shields are broken, it will be paralyzed for a full 13 seconds, which you should take advantage of by using all your Elemental Skills and Bursts. The best element here is Cryo, as it can destroy two of the three shields. All that's left is the Pyro shield, for which you can bring a Hydro character.

The second wave features two mobs, but they are not much of a threat. You should consider generating Elemental Energy to refill your Bursts for the next Chamber.

In the first and only wave, there is a single Radiant Moonfly. Its core mechanic is inflicting the Radiant Cocoon debuff on your team. This debuff will decrease your characters' Crit Rate by 100%, DMG Bonus by 50%, and Incoming Healing Bonus by 40%. Healing the whole team to 100% HP removes the debuff and grants the Disentangled buff, increasing their Crit Rate by 15% and their DMG Bonus by 50%.

There is only one wave here, featuring Battle-Hardened Elite Treasure Hoarder (known as the Local Legend Hiljetta in the open world). She will summon her battle armor on the field; you can see it from the line connecting her to the battle armor. There are 2 ways to prevent the armor from attaching to her body: either trigger the Frozen reaction on Hiljetta or trigger the Overload reaction on the battle armor.

If the attachment is not interrupted, Hiljetta will successfully equip the battle armor and enter the Armored State. The Armored State packs quite a punch, but you still have a chance of survival by avoiding all of her incoming attacks until it's over.

In the first and only wave, we have Chimeric Winged Lion. Once the challenge starts, the boss will spawn with an Electro shield. The best elements to destroy it are Pyro, Cryo, or Dendro. However, you can also use Stellar Glimmer reaction to reduce the shield more effectively. Once the shield is broken, the boss will be paralyzed for 13 seconds, and its RES will be reduced to 70%. That's the best window to unleash all of your attacks.

The boss can also summon 5 Anemo Orbs. After absorbing 3 of the Orbs, it will fill the bar and the boss will continue attacking you. Destroying 3 or more of these Orbs with PHEC elements (Pyro/Hydro/Electro/Cryo) will paralyze the boss. Another option is to use the Stellar Glimmer reaction on the boss. It will instantly destroy all the Anemo Orbs and paralyze the boss again.

At the last stage, you will face Secret Source Automaton: Overseer Device. When the battle starts, the boss will immediately enter a state in which it can unleash its powerful attack. In this state, you can see the Flow Momentum bar under its HP bar. You need to use Cryo attacks to reduce the Flow Momentum bar as much as possible, which will disable the boss's Ultimate beam attack and reduce all of its RES.

Another option is to use a Natlan character, as their Nightsoul's Blessing state will make the enemy accumulate Adaptive Countermeasure. Once the Adaptive Countermeasure progress is complete, the boss will enter Counterstrike Mode and deal huge damage with its water jet. In this mode, its RES is also reduced. In conclusion, you have two options for facing this boss: either use a Cryo character to reduce the Flow Momentum bar or use Nightsoul's Blessing from a Natlan character to accumulate the boss's Adaptive Countermeasure.
