Hm, looks like there's not much else I can do from inside the shadows, not while she's up in the air. I've been firing out some Spells up at her, but she's easily dodging them.
Since there aren't any pillars or large rocks nearby in or around this area, the only shadow I can use is hers, which also means that she knows exactly where my attacks are coming from.
Coming out of the shadows will be risky, I'm basically untouchable while down here, but...I won't benefit from this as much by playing it safe as I would if I took some more risks instead.
Hm, if I emerge from her shadow, she'll see me coming and be able to react easily, giving me no element of surprise to work with. In that case...
I then fired out lightning bolts up at her from shadow, which she swiftly countered with her own lightning, more powerful than my own attacks, canceling them out and shooting down towards the ground.
