I've finished this version of the Spiral Abyss with these comps.
Notes:
1. Always use the Blessing of the Abyssal Moon to your advantage. This Spiral Abyss centers on Anemo characters so if you do not have a 5-star anemo character, considering Sucrose is the only 4-star anemo at the moment, use your traveler.
2. Floor 11 is the easiest because of the Swirl damage bonus.
3. Always prepare your Anemo characters' burst before ending a chamber for fast clear on the next one.
4. I used Geo characters (Zhongli and Ning) because I don't have other characters built, which may have limited elemental reactions. For this, I suggest building Xinyan and Beidou for shield + better elemental applications.
5. 2-pc and 4-pc artifact effects are secondary in priority. Use artifacts that give the best stats even if they are from different sets.
6. Take your time with floor 12 if you know your characters deal peanut damage. There's no pressure in the amount of stars you collect on that floor unless you really want full rewards.
