So this is pretty normal for hard mode, right?

Running a lightweight gauntlet build at level 24 right now and I'm noticing the lowlands boss is sponging a lot of damage and getting shredded in two hits.

Boss itself isn't super hard to get a read on thankfully but a minor whoopsie or two keeps sending me back to the whisper.

So I'm just curious if this is about the average experience for hard mode at this point and I just gotta tough it out, or if I've missed something and I'm supposed to have a build that tears this thing up like toilet paper in seconds or the like?
