How to Beat 3.0 Spiral Abyss Floor 11 & 12 in Genshin Impact 3.0
Floor 11
Floor 11 is the second the last Floor in the Spiral Abyss in Genshin Impact.
Before you start clearing this floor, you must take note that all characters in the party gain a 75% Dendro Damage Bonus, and the enemy level is 88 – 92.
On this floor, you will be able to get a blessing of the Abyssal Moon: Efflorescent Moon
- After characters deal DMG to opponents with a Dendro Core, their attack will be increased by 15% for 8 seconds. This effect can stack up to 4 times and can be triggered once every 0.1 seconds.
Best Characters to Use:

You must make sure to have at least 1 DPS, because this DPS will either be accompanied by 2 sub-DPS and 1 Support or 1 sub-DPS and 2 Supports.
It is highly recommended to use Dendro Characters. Floor 11’s Ley Line Disorder will provide a 75% Dendro Damage Bonus, and if your characters are under-leveled then you should use a Dendro Main and sub-DPS for the first and second half from the party.
In the first half, a lot of enemies in the second chamber can be affected by Frozen, and that’s why you should use Dendro or Cryo characters to take out the enemies faster.
In the second half, you will encounter a bit heavier enemies, and it is recommended to use Pyro, Cryo, and Anemo Main DPS characters that can deal a lot of single target damage.
Floor 11 – Chamber 1
At this point, your challenge will be to defeat a total of 18 opponents.

In the first half of chamber 1, most of the enemies can be controlled by Venti, Sucrose, or Kazuha. You will want to use their Elemental skills and Bursts to stop the enemies.
In the second half of chamber 1, use characters like Ganyu, Amber, or Tighnari, and use their Elemental skills to have the Mitachurls distracted.
You need to know that Shieldwall Mitachurl will want to attack you first and to avoid this make sure to take out Axe Mitachurls first.

Once the Thunderhelm Lawachurl shows up, use Cryo or Dendro attacks to quickly destroy the shield.
Floor 11 – Chamber 2
At Chamber 2 your challenge will be to defeat a total of 22 opponents.
In the first half of chamber 2 is best to use Freeze to immobilize the Hydro Mimics. Don’t use your Elemental Bursts, instead save them until a bubble shows up when beating Hydro Mimics.
In the second half of chamber 2, you need to use shields to immobilize the Geovishaps. To take advantage of the Dendro buff, use reactions such as Aggravate or Bloom to quickly defeat the Geovishaps.
Floor 11 – Chamber 3

In chamber 3 your challenge is to defeat a total of 7 opponents.
In the first half, you need to use a combination of Anemo Crowd Control and the Frozen reaction since the enemies here are light and can be easily frozen.
In the second half, attack the Electro Regisvine’s weak point which can either be found in its head or in its roots. It is best to use Dendro or Cryo attacks to destroy the weak point faster and take it down with Dendro reactions or Vaporize.
Floor 12
Spiral Abyss Floor 12 is the final floor of the Spiral Abyss domain.
For this level, the Ley Line Disorder flow will be normal. The enemy level is 95 – 100.
Best Characters to Use:
It is highly recommended to choose 1 DPA, then either 2 sub-DPS and 1 Support, or 1 sub-DPS and 2 Support, depending on which characters you have available.

Use cleansers on the first half, because they can clear any elemental debuffs on your character. This can be a form of full cleanse like Jean’s Elemental Burst or applying another element to your character.
Floor 12 – Chamber 1
In this Chamber, your challenge is to defeat a total of 11 opponents.

In the first half, you have to lights on either the Eye or the center body of a Ruin Drake when charging up for an attack. If you hit these spots, it will get stunned and you can deal huge damage in a short period. Melee and AoE attacks often work against grounded Ruin Drakes, but also you might need a bow to hit the flying versions.
In the second half, approaching Pyroslingers will cause them to jump back, and you can use this opportunity to make them jump to a nearby Eremite Crossbow enemy that can deal a lot of AoE damage.
Floor 12 – Chamber 2
In this chamber, your challenge is to defeat a total of 5 opponents.
In the first half of Chamber 2, the target priority for the fight is the Electro Cicin Mage, then the Crossbows, and last Mirror Maiden. Mirror Maiden is last because has the highest health. You better take out the DPS first because it will give you a higher success chance when you leave the tank last.

In the second half, you need a shielder that will protect you from the AoE Pyro blast attack. If you are not able to use shielder, then make sure to save an Elemental Burst for the invincibility animation and prevent damage.
Floor 12 – Chamber 3
In this chamber, your challenge is to defeat a total of 7 opponents.
In the first half, it is best to take out Bolteater Bathysmal Vishap for the first wave of the first half. The enemies will drain your Energy Recharge, and after that you should focus on defeating the Primordial Bathysmal Vishap with the Hydro Aura.

In the second half, you must take note when fighting a Jadeplume Terrorshroom, don’t hit it with Pyro, but instead, hit it with Electro.

If you hit this enemy with Pyro, it will spawn additional enemies, but if it’s with Electro, it will fill the circle on the bottom left of its Health bar.
Once it is filled up with Electro, it will eventually get exhausted which will be your chance to deal lot of damage to it.
