Wow, so this is the modern japanese definition of Hell mode where it just means you need to grind more and have a 99.99% exp penalty.
I remember when Hell mode used to mean no retries, everyone hits you hard (one shot), and skill, planning, tactics, and memorization is more important than grinding or stats (not to mention leveling up to 4 levels already doubles your stats).
Also, why is "farmer" a social class? Shouldn't it be serf, indentured servant, or something similar instead? A farmer is an occupation, not a social class. Unless its a matter of citizenship, but well.. w/e. I'm thinking too deep into this, since obviously the author didn't put much though into his world building. (I've been spoiled by bookworm too much, and expect every isekai to have its level of world building).
