She’s supposed to be some princess that avoids direct battle. Think about it - one tree is focused on sniping, which involves hanging back and picking enemies off before they can react. The next one is all about freezing enemies, making them unable to fight. And the last one just gets someone else to do your dirty work for you.
It’s brilliant…but still annoying lol. No wonder she’s lacking so hard when it comes to staying healthy, particularly during solo boss fights.
