They won't nerf shit dude
This is what they originally intenteded hollow knight to be
They designed the game around 3 masks from the beginning. They only upped it to 5 as a last minute decision. Back then, it was probably the right move as the lessened difficulty probably helped it go mainstream, but now that they've made it they have no need to pull punches at all. You start with 5 masks but it may as well be 3 because every enemy that matters deals 2 pips right out of the gate. I just got my fourth mask shard, so I'm up to 6, but that still means I die in 3 hits from every boss lol. Only the fractured skull is able to act as a crutch, but even that isn't enough most of the time. Also, it's basically garunteed that by the time you have something like 8 masks, you'll be dealing with 3 pip damage enemies and bosses lol
