Yeah my pool of charatcer is pretty nice also so I just kinda used my strongest. Never really took the abyss seriously until now and I just cleared it full it with 36 stars. Can't really remember who I used for floors 8-11, but for Floor 12 I ended up using Ayaka, Diona, Mona and Venti and my second seam was Raiden Shogun, xinqiu, bennette and Xingling. Pretty much crushed it. My second team with Raiden shogun was really fun. The high tide low tide shit in floor 12 is really annoying, but I pretty much had my Alts up at all time.I've got a pretty big pool of reliable characters to choose from, so it's usually whoever fits the situation, but for sure I have Zhong Li + Hu Tao on one squad, and Noelle + Ning on the other.
