Magic potion is a necessary item for hunters to travel at home. The potion is very powerful, but it is only suitable for hunters. Ordinary people will die instantly after drinking one mouthful.

Magic potion can enhance the hunter's ability to surpass human beings, but it also has its limitations. If you use too many potions at a time, even powerful hunters can't carry them, so Geralt uses them carefully every time.

The birth of the demon hunter:

No matter which faction you come from, becoming a demon hunter is a painful process. Generally speaking, the candidates for hunters are all little boys, usually orphans or children abandoned by their families. Joining hunter school is their only choice.

Children who survive through a series of training have to face the grass test, that is, the process of normal boys becoming mutants. In this process, the survival rate is only three tenths. Although cruel, hunters will form a lifelong emotional connection with them. Especially the relationship between Geralt and his mentor Vesemir, Vesemir regards Geralt as his own son.
