Take the time to build supports and stuff if you haven’t already. you can use this guide if you need help. it really helped me. floor 11 is easy for me, except this time I wasn’t able to do it all the way because I have no good cryo characters,
That is one of the reasons why I am imo rather weak and struggle with endgame content. Abyss became too hard now and I cannot even complete floor 11 like before, and the theater is pretty hard I often even fail doing it on normal. If only you could just brute force through it all with the mains but alas
if you don’t have many supports, I recommend taking a break from pulling dps characters or faves,, and pulling supports or characters that’ll be good for your account like Xilonen, kazuha, citlali, nahida even. Also just building the good 4 star supports can help in end game modes. For theater, you can put a crappy build on a character and still complete it just fine. but if you do already have those characters, then great. building supports for teams helps a lot in abyss. for Abyss, you can do it just fine with even just 4 star characters, you just gotta know how to build the, and what rotations and teams to use. I’ve been getting a lot of help from my whale friends who know more about that kind of stuff. And I love giving advice to others who also need it. Definitely pull escoffier when she reruns for your skirk, if you haven’t already.
