How to parry Rellana - Elden ring DLC boss 

when she pulls the 360 and re-swings back when do you parry on that, on every other move she does i can parry but not that 360 move, any tips?

can you parry any attack? or only sum

How do you time the parries? Or do you just pre fire the parry when she pulls her sword back?

Vu comme ça, elle ne paraît pas si effrayante...
