Q: I put in a lot of effort killing Wild Silver Zlimes since I was told by NPCs that they gave a lot of EXP, but I’m not leveling up at all. Is this a bug?
A: It’s a bug. Due to a mistake, the experience granted by Wild Silver Zlimes and Berserk Rabbits had been switched. Go search for and hunt Berserk Rabbits instead.
Q: The healer in my party is not leveling up at all. Is this a bug?
A: It… would be great if it was a bug, but it is how the game is. In this game no matter how many times one casts healing magic, they would receive no experience. Either try to find a new, higher leveled healer, or try your best to let them deal the final blow.
Q: The healer in my party leveled up, but their recovery magic did not become any stronger. Is this a bug?
A: It’s… not a bug, but how the system works. When leveling the healer, if they dealt the final blow with a physical attack, then even if their class is healer, their physical statuses are what will increase. Either try to deal the final blow with magic, or give up and treat healers as consumable items.
Q: A certain magician joined our party, but doesn’t listen to commands and goes berserk, and even burns other party members with offensive magic. Is this a bug?
A: The existence of that character is something like a bug.
