In general, people call it "mechanics" as in MMORPG you know... To defeat boss, you need to perform mechanics or possess the best weapons. There is nothing wrong with mechanics, if they annoy you, then just break all webs. I did this in my first playthrough because I thought she was only moving around with them.

Then my whole party died.
In the future, you can kill her with better weapons and a higher level, without mechanics.
I spent 4-5 hours. Without webs. But I killed her. I think it will be easier at a higher level. And I repeat, she doesn't always jump on the web! Very often, it can teleport directly to you, ignoring web.
