She should not be this hard, but I rely heavily on healing as part of my defense and she's owning me. Anyone got some advice?

It's not just you, she is pretty difficult! When healing is disabled, the best strategy is to protect the little health you do have. The gold standard for that is blocking.

Now let's look at her opponent info over here. Her weapons deal mainly dark and earth, with some fire, water, and physical mixed in. You basically want to use weapons and scrolls that block those elements (:block:dark::block:earth:|:block🔥:block:water::block:physical:) to conserve your health so you can outlast her.

For weapons to add to your set, a great constant for her would be Maliss Cannon, which blocks dark and earth. There's also Shrine of Apollonia, which activates a blessing that provides some extra dark and earth coverage for several turns. You could also use a shield like Item Defenders Shield, which is good for conserving health since it blocks a bit of each element.

In terms of scrolls, Aftershocks Scroll is going to be the best infinite use scroll for her, but if you need something cheaper, Feather Explosion or Fiery Death would also be decent choices. If you want some once per battle scrolls to round out your set, Spacial Abyss Scroll is the best when it comes to opponents with healing disabled. It blocks a lot of icon types and you won't suffer from the negative heal. Cobalt Eternal Scroll also costs a similar amount and blocks most of the icon types she uses. If you need something cheaper, Fatal Fire would also be okay to use here.

Lastly, for your mod crystals be sure to add a few Blessing of Natural Armor Tear Crystals to prevent her from stealing your weapons.

I do have aftershocks, I'll toss it into my scroll line up for her!

Thank you so much. I'm gonna go grab some of those items you mentioned. She's just rolling me every time lol
