The Spiral Abyss's 9 and 10 are the easiest floors to play, but they can still cause problems if you go into it unprepared. If youre newer to Genshin Impact's endgame content, check out this page for a jump start on how to defeat the Spiral Abyss.
Each Spiral Abyss update includes a unique feature to aid you through your battles. This update is the Blessing of the Abyssal Moon: Efflorescent Moon. This buff has the following effect:
After characters give DMG to opponents with a Dendro Core (including Burgeon and Hyperbloom), their ATK will increase by 15% for 8 seconds. This effect can be triggered once every 0.1 seconds.
The Spiral Abyss'floor 10 contains an additional Leyline Disorder that reduces the effects of the spread and aggravate reactions by 75%.
Characters to consider
The Leyline Disorder of these floors motivates you to bring additional Dendro teams. Aggravate and Spread reactions can only be triggered by combining a Dendro unit with an Electro unit, while the general Blessing of the Abyssal Moon is best utilized with a Dendro + Hydro unit.
- Tighnari: Tighnari is stronger on this floor, as the Leyline Disorder for this floor helps out Tighnaris best team, which consists of pairing Tighnari with a strong Electro applier like Fischl or Yae Miko. Aggravate and Spread are strong reactions, and Tighnari is a good unit that can take advantage of the buff on this floor.
- Keqing: Keqing got a big buff with the addition of the Dendro element. Aggravate and Spread are strong reactions, and Keqing is a great on-field Electro DPS. As a result, take advantage of Keqings newfound strength and try her out on this floor.
- Dendro Traveler continues to be an essential Dendro unit for applying Bloom and other Dendro reactions. The main character is a highly recommended unit to invest in.
Floor 10: Chamber 1
The first half of Chamber 1 is very similar to the first half of Floor 9: Chamber 1. You will encounter Fungi and Shrooms that appear in waves of three, and you may want to consider bringing a ranged character for a winged Cryoshroom.
The second half of Chamber 1 consists of two Primordial Bathysmal Vishaps. Tighnari is recommended you bring him on this half because his single-target DMG is a bit higher. These enemies are a little tankier, so bring a strong single-target DMG like Yoimiya or Hu Tao.
Floor 10: Chamber 2
If you do not defeat Kairagi at the same time, you will face five opponents in the first half. AoE damage is best brought by teams with strong AoE damage.
In the second half, you will have to face a single Thunderhelm Lawachurl and Electro Abyss Mage. The Electro shields will be burst down quite rapidly. Start by damaging the Thunderhelm Lawachurl first, as the Electro Abyss Mage will teleport to you.
Floor 10: Chamber 3
Three Eremites and two Fatui Skirmishers will be encountered in the first half. If you are lacking damage, make sure to target the Fatui Skirmisher Hydrogunner Legionnaire first. This enemy can heal the other enemies, so it's important to dispatch the enemy first.
One Mirror Maiden and two Fatui Electro Cicin Mages will be fighting in the second half. We recommend you combating the two Electro Cicin Mages first, as the flies they summon can distract from your teams damage.
