Rabbit and Steel Wizard Solo Hard Clear

So, I heard Wizard was going to get buffed at some point, so I thought I'd get a clear before that so I could say "I did it before the buff." It's only hard, tho. I'm still working on Lunar, and considering Wizard was one of my least proficient character in the demo, I wasn't gonna get Lunar clear anytime soon.
I cleared hard a few times now, but I actually had not realized the last boss was on her own stage until I noticed my life was at 5. I should have known with the stage name flashing and all that, but it never occurred to me.
Anyway, I think I have most mechanics down, and I get hit because I make mistakes, and not because I didn't know what to do except maybe Pale Keep and the final boss. I think I know most, but I need to figure out some more.
My DPS felt a little low going into the last phase, so I wasn't 100% sure I was going to get it this time or now. And when my life got to last 1, and the boss started enrage sequence, I thought I was done for, but I barely cleared it.
And the adapt palette is pink! I always wished she had a pink palette, and I guess it was behind a hard clear.

How do you target an AOE between two enemies?

[@shiawasagi]

Hold down the change target/focus move button. L1 on controller by default, and I'm guessing shift on keyboard by default (haven't played with keyboard)

@@shiawasagi oooo thank you so much!! I’ve been WISHING for something like that, that’ll make that one double mouse fight where they heal each other MUCH easier!
