there is content with permadeath. its called BA though there is a way to res it is extremely limited. its either 70% chance to res or a spell that kills you to res another. i can assure you if you missed it was hellah fun. it wasnt extreme difficulty but every ability oneshotted so you had to be extra carefull . the peak ofc being the final boss ozma an extreme version of it which you could wipe 52 peeps for one mistake. can try to get into it but it requires a discord server and a whole lot of luck. also you need to get through eureka.
