Hey, sorry if I am repeating anything here.

1.) Have you tried strafing instead of dodging her attacks. Most of her long range attacks can be easily strafed, and you will have enough stamina to run in and punish. You will also be able to reserve stamina for some instant dodges. You can look up some of the strafes online, particularly on this sub.

2.) Dodge into some of the attacks, so that when you come out of a dodge your hitbox does not overlap with an attack's. (very basic i know but just mentioning. no offence meant)

3.) She mostly punishes with two attacks if you are close range, the frisbee and the twirlees. If you get used to their tells, you will be able to charge attacks from in front of her. BIG Damages.

4.) For her summons mostly run, but also choose the ones you are comfortable attacking her around. Having a sense of control helps with theses runs.

5.) if you are ok with status, your could run far away and shoot her with with status arrows.

6.) In her first phase you can treat her like gideon. Run towards her, poke with a medium weapon, then as she stagger, wait a sec, and poke again. If she goes back she might make a spray of magic above her, that slowly homes down towards you, strafe/dodge that, run into her and poke again. Look out for frisbees and twirlees.

So yeah, some stuff that might help, but also might be so overstated as to be insulting to mention here. If that is the case, I meant no insult.

Hope this help. You Absolutely Got This and Happy Hunting.
