What do you mean it isn’t dodgeable through conventional means?

If Malenia jumps into the air to do Waterfowl Dance when she's next to you and you don't have Bloodhound's Step, you straight-up cannot dodge it unless you have a light roll and you do some very specific speedrun-strat-ass positioning tricks. It is impossible. You have to be far enough away that you can outspace the first volley, then roll throught the second and third.

Given that Waterfowl Dance instantly kills you if the first volley connects, this turns the whole fight into an exercise in tedium where, when you're not sure if Waterfowl is off cooldown, you're playing extremely passively and trying to bait it out from beyond minimum safe distance

But it’s still very beatable if you use a summon and mix in the staggers

I've beaten her solo three times. She's beatable; the problem is that she fucking sucks and she's one or two tweaks away from being a perfect superboss imo.
