Revision of the Battle System

Earlier during combat, an ally character suddenly attacked the player from the start. It wasn't a betrayal—it was Franz's mistake. Franz's behavior gets weird during combat. His dice rolls become absurdly strong, landing two critical hits in one round with consecutive 18s and 19s. He made one player fight four high-level creatures. Both the battle balance and the dice rolls are blatantly overpowered. Plus, the ally character attacking earlier was a mistake too. When I asked him to fix the HP, he said the “log” disappeared. It was in the log right before, so that's weird. Franz is fine for enjoying conversations, but the combat system is completely useless. The battle system needs maintenance for a while.　

I've also removed the campaign. I'll bring it back once the battle system is improved.
