The concept is good at the core, but rest made poorly.
Most annoying part of crucible is plague flame attack, seems like every knight has it, when dealing with multiple enemies, it becomes harder to spon, since player need to pay attention for every enemy, to doge attacks, absurd amount of damage it does makes it even worse. And they can cast it of the screen.
Enemy placement - they see far, and strike hard. Just was in a run, and what seamed like a good distance to draw to me only one enemy, wasn’t enough, knight ended up running at me with a shield. They put so many enemies close together so game becomes a rolling stone simulator, dogge that, dogge this, do one attack with 2-handed sword, and keep rolling,
Embers - It’s okay to have currency for such things, what is not okay, is that you have no idea where to find this stuff reliably, going around the world looking for every chest, hoping it will has an ember is insanely time consuming, Feels like game loves to waste players time
Repetitive - 10 stages, 6-8 enemies, over and over again, nothing much differs from run to run. I want to play crucible less and less, as I level up, it becomes so boring and mondain. Yes it proposes a challenge, bur lacks a kick to it
So I felt the same way, was having fun through the story, first 20 runs were fine, and slowly it stopped being engaging at all
