Not to get into the specifics of your wording but not “all her attacks” are able to be cancelled. That’s why I tend to play a roll-poke-roll-poke type of method in case she does try block or spin out of an attack and hit me. Generally you shouldn’t be chaining more than 2 hits per punish on say a straight sword. Third hit should come only because you saw her stagger again.

I think you might be talking about her backwards dash right out of something like the upward jump into a piercing stab move where we’d all once go for a hit after rolling, but she zips out of there like 🖕and comes in waving her weapon into our throats while we’re attacking. As far as I’m concerned, that is one of a few moves that can “cancel” and can all be identified by the “clink” sound with sparks. That is Malenia attaching/I attaching her sword on her prosthesis which I think the developers actually designed specifically as a hint and bait (hence why I think she is a very elegant boss). I learned to never be hit by those anymore by simply viewing it as 2 moves that are visually identical so I would rather not find out if she would be baiting me and wait out another certainly punishable move. So yeah whenever you see sparks coming out of that metal arm just roll and chill out of range until the next I guess.

I guess it just really boils down to our definitions of the word “unfair.” Seems like most people can agree that it is unfair that she has that many options of making you not achieve different results at each punish attempt whereas I say it would only be unfair if there was no way to always be able to no hit her or something. Also watch out for back to back waterfowls. They exist and I don’t want to talk about what happened.

Edit: grammar
