Generally speaking, humans become powerful by fighting in battles. Such qualities as strength, defense, agility, and mana will upgrade depending on the weapons, armors, and magic books that have been used in the battles. HP goes up regardless what items and equipment were used. While fighting the enemy increases the various characters' HP, their growth rate will not at all be equal. The stronger the enemy, the more powerful the characters become. Since the humans do not possess any special skill, they must depend on the items they carry. Humans can use any items they wish and can carry up to eight.
The basic system of growth for mutants is equivalent to that for humans, but the rate of growth is a little slower. However, they have a much higher level of mana and can acquire various special abilities by fighting battles. Mutants can carry up to eight items, of which a maximum of four can be special abilities that can be acquired. Mutants can acquire these abilities if there is room on the item list. If their capacity is full, the newly acquired abilities is exchanged with the last one on the list. It's best to let them become powerful by using a lot of special skills and upgrade their mana. It's also a good idea not to give them too many weapons since they acquire different special skills as they become more powerful.
Robots don't become powerful as a result of fighting in the battles. They can raise the HP and the values of abilities by equipping the weapons and armor. In other words, the more weapons and armor acquired, the stronger they become. They can equip themselves with any available items with different degrees of power. When robots have used up their weapons, the player shouldn't not throw them away. If the robots are staying in the inn, such weapons will restore the capacity to fifty percent of the maximum number that can be used. However, the operating level of the skill items will not decrease but they will not be restored at the inn, either. It is recommended that the robots be equipped with as many powerful weapons and armors as possible.
Monsters don't become powerful by themselves. They can transform themselves into another monster by eating enemy monster's meat, which may occasionally be dropped after the battle. Whether or not they become stronger depends on the meat they eat. They need to eat the meat of a strong monster to become stronger. They should not miss the meat of boss monsters when it's available. They may become weaker, however, by eating the meat of a weak monster. Once the monsters become strong, they should not eat the monster's meat unless the player are sure that it's the meat of a very strong monster.
