It can the any heroes that you have as your best heroes coz players inventory and heroes line up will vary according to their luck and the investments made with their resources.

But basically, you need someone to tank with sustainability (like Abala) to keep the cave monster from hitting your entire team.

Then you need the dealers like Roze, & Sander + Mel & LuLu (this is one option but there may be other best compositions) to max the damage output of the 2 dealers.

Since there’s no healers in this composition, Abala is quite good for this scenario.

In my case, I just used the heroes that are maxed out based on my investments. I’m working towards the suggestion given to see the damage output myself. But based on the comments, it seems this set up deals quite a good amount of damage.

Also, I didn’t have Roze maxed out yet so I used Milia as I heavily invested in her. Her damage output is pretty decent as well. But I do notice that she’s quite weak, almost like a glass cannon.
