Game developers always, always, always make their games too hard. It's because, if you made the systems, poured over it for dozens of hours, you will always overestimate how well people do at the game. I had to grind the final fight until I got lucky with my "sacrifice" card stacking with a x2 bonus. I don't think there's any other way to win that fight.
The game would be tons better with an 'easy' difficulty. Other than that this is an amazing game!
No hate, but I think you may have misunderstood a game mechanic. The parries cause the x2 bonus so you could have tried to tank some damage to save up dice, build up parries and then time the sacrifice. The difficulty isn't really a problem, just the dice make it seem a lot more random than it really is.
take the roll one more die per turn lose 10 health, roll a die cooldown 4 turns, flip a die and add 2/3 value to a die. use them every time you can, every turn you can.
use the plus 2/3 on 5's and 4's respectively to make it into a 6 and overflow a 1 that you then flip into a 6 every turn.
until the duo crock and crane fight on day 3 swap out the roll one more die per turn lose 10 health for passively deal 3 damage every turn, swap back after for the last 2 fights.
