Over time, changes will begin in your world: monsters will become stronger and more dangerous. All this is due to the new scale - difficulty. You can find out its meaning by creating a Hardometr. To influence the difficulty, crystals were created: cursed and enchanted. The cursed increases the difficulty value by 10 points, the enchanted decreases by 10 points. Crystals can be found in underground dungeons in the normal world (stronghold, mineshaft, monster room).
