Is this abyss not good for arle?

Okay so i'm sorry if this isn't the right place for this but i just gotta ask. So i finished my second team which is raiden overload so i can finally take on spiral abyss. And i was able to sweep up to floor 11 with ez with arlecchino vape and raiden overload. But as soon as i got to floor 12 i was having issues do these enemies just have high resistance to pyro and electro? Or is this just a skill issue since this is my first time taking on abyss?
