Hello, I am trying to add a tech for the human race in which to be investigated will grant magical immunity to the peasants, but for some reason does not work. I created a new tech and in the tab of "effect" I selected "Immunity to magic" and added it to the "Tech used" tab of the peasant. I have tried many ways but none works. How can I do so that through this investigation the peasants possess magical immunity? If possible without skills/abilities, since I want to do it with tech upgrade. Sorry for my bad english, I'm desperate.
