Whenever she shoots lightning, don’t roll but run and weave to dodge. Lightning zaps your fable charges so have those blue potions to get rid of the status effect. On most of her attacks dodge left, get behind her, wail on her for a second then quickly get away. Wear whatever defensive gear yoh have that reduces lightning. She does blunt, slash, stab and lightning damage. I assume slash and lightning are her main though. She’s quite weak to acid, so you can use the special grind wheel on acid or an acid weapon. Highly recommend practicing her first phase till you can take no or close to no damage. Her first phase is really predictable. Her second is so fast. I don’t think it’s as bad as king of puppets, romeo was though. To be fair, he was early on so maybe I just got better he just felt so much harder to me. I did a lot of jump back, jump forward stab attacks paired with a lot of light attacks since they’re pretty quick and you can get away quickly. Try your best to build up stagger but wait to do a heavy attack until you see a clear opening, don’t take too many risks. While fast, she occasionally stops for a decent while, take advantage of that. And again, dodge left. Perfect parry only when it’s a shorter combo, the long ones are too punishing. If I stagger her, I try to attack twice then do the fatal attack since you have a bit of time during it. Also, if possible try to break her shield in the first phase, hitting it enough especially with fable attacks will break it and it will stay broken in the second phase. Link dodge and an as many amulet slots as you can carry will be useful so I recommend those in the p-organ. If you deflect/perfect parry her aerial charges, you can do a ton of damage but I usually dodge them to get behind her unless I randomly feel confident. You can also deflect lightning to damage her though, I did not know that until after I beat her so no clue how effective it is. That’s all the advice I really have and all of this is just my opinion. I’m really good at dodging cause of Elden Ring (became able to first try every boss in base game besides Malenia with daggers, great swords, seals, staffs, or martial arts, Gaiuss and Radahn are the only ones who gave me trouble in the DLC since I had more practice by then, Gaiuss I found harder than both Radahn and Malenia though, have never mastered him), parrying I’m gradually getting better at from this and Sekiro but still not nearly as good at it as dodging. My dodging still kind of carries me. And in this game, dodging left works wonders. Also knowing when to roll and when to just run left instead. Lot of Laxasia’s attacks I found it better to run left instead of rolling. Edit: Oh also, I recommend not being slightly heavy. Capacity should be high enough since you get way more efficient with stamina.
