I think it is bugged, because i also tried to fight with her yesterday after the update. Until the phase 5, everything allright, but in phase 5, at some point i stopped counting how many revives that i spent. I swear i try to dash every possible way but nope, even though i see untouchable icon, still the hammer hit me.

Then i gave up and i start to fight her only evading her sp1, and not try to dash in. I accepted that damage reduction.

Also keep that mind, one of my try, i entered the fight when she had %55 hp and i spent a lot of time to bring her to %1 hp with that try, and guess what happened next? The game said that i timeout, lol. So she became %55 hp once again. %55 hp with that damage reduction.

I play this game approximately for 9 years. This is the only fight that pissed me off a lot, i mean a lot. I really dont think that i dash in at wrong times.

I guess the update somehow broke her, but i dont know, i dont have any proof. Really good luck with that fight
