There was a dazzling array of various types of mutant blood potions. There were even more than ten sets of fatal-risk mutant beast potions that were rarely seen outside, including the works of masters.
According to the formula of the Mutant Blood Potion, there was a huge difference in the final product's effect if the ingredients of a mutant beast were mixed with different herbs or ores.
The better the formula, the better the strengthening effect on the body. It would inherit the stronger characteristics of the beasts, and the less likely it was for there to be side effects, reducing the chances of death.
