NettetGametic mutations occur in the reproductive organs (they occur in the testes of males or ovaries of females), usually during meiosis, when the gametes (eggs and sperm) are being formed. These are passed onto the next generation if the resulting gamete is fertilized. This mutation is consistent in all parts of the body (though that doesn't mean ...

NettetIn another words just using neutral mutagens will not cause you to mutate, it'll just increase your neutral Mutagen value. So if you want to mutate in the Ursine branch for example, you'd want to first increase your neutral Mutagen value through standard mutagens, then use an Ursine primer or mutagen to increase your Ursine value.
