Lythara is just ridiculous

So Im leveling a new character because of the endgame changes and I can not get past her.

I have really good twink gear and she still almost one shots me with her lightning spear attack that creates those chaos fields. We are talking about roughly 3k HP/ES and maxed ele res (chaos at 30%) which is way better than any normal league start character would have.

In the second phase their is almost no save spot in the arena and she also tends to of screen you.

WTF

Just to put it into perspective, I beat original unnerved Azmadi at league start in 3 to 5 tries (don't remember the exact number) which implies that I'm not completely bad at the game.
