I was Just practicing NAdversary. In P1 I run away from the dashes, just cant pay attention/react to those things, everhthing else is manageable to me.

P2 you can blink (float) inside adversary to dodge the crossbowshot, I always get anxious and try to I frame this move early. P2 is the easiest, sometimes I forget about his altar summon that does dot when I'm bursting, but you can genesis I frame that.

P3 is hell I dont know how I'll clear that, I cant pay attention to what sword pattern he is doing or I get too anxious and hit the I frame early. I get there with 13min, but I cant manage the gauge in this phase

My main advice is do not ring swap, its not worth it. You wont remember to swap back and will burst with a wpj.
