Not sure why my experience with Ebrietas was so different... I purposely waited for her charge (while keeping at range), dodged it and then went in for the attack since she wouldn't do anything for a bit after the charge. Maybe its bad if you stay close, I'm not sure?
It's definitely avoidable at large distances.
I guess what my issue is is that her geometry doesn't match the hitbox. It probably wouldn't mind it as much if it did. So many times it looks like I'm nowhere near her but then I see my health disappear.
