"There are 3 types of attacks: Normal Attack, Physical Skills and Magic Skills. But if you repeat the same type of attacks..."
"The damage dealt may gradually decrease. Enemies get used to the attack and it becomes less effective."
"But it might be a chance. When enemies get used to the attack, the defense against other types of attacks gets weak."
"So, if an enemy gets used to normal attacks, you can deal more damage than usual with physical and magic skills."
"Well, some monsters get used to attacks easily, some don't. So when you notice the damage dealt decreases, you should change the type of attacks."
