Scarred Raven.

The drug is meant to heal the most severe damage to the body. Even someone that has only one breath in them can be brought back from the brink of death and saved.

The drug is so powerful that it only left the barest scars on his body. It also had enough energy to help his body transform for the eighth time. That's why it had cost nearly a thousand gold coins to buy.

After his eighth transformation, he lost control of his body as usual, but it wasn't as severe as the previous times. It is because his upper limit of strength had increased from 14 to 16.

It was just a 14.3% increase in strength, not 100% or 50% that he used to experience when he was very young.

His control over his body had also become better over the years. So this increase of 14.3% didn't affect him much.

The impact was so small that even his mother, who had known him for many years, didn't know that he had grown stronger. He still had to train his body, though.
