so far defeated the boss now with the trial characters and it took me like 10 or 15 attempts i think, most of the deaths was due to me trying to do it the hard way(not using rotation) but in the end i decided to do it the easiest way first, now the next thing i need to do is to win it using only alpha and no support. then i will try to no hit it after doing that
Nah, all phases, even if we count phase 4, after her big circle trap gets dispelled. See 0:15 for example. Phase 1 whenever she is staggered/juggled, she will definitely make a comeback move and there's a chance it will be the parriable attack (step back and purple flash then stab forward). She also may do that in phase 2 after you break her game rules, then her moveset returns back to being like phase 1's.
7000 BP xD. Watch my "Satisfying Parry" video, you will know. SS + full memories build and her Signature weapon "Nightblaze" (with 1 weapon resonance - Dead Line Timing). Oh yeah, and also her Signature CUB - the motorbike.
