Ok, thank you. So I "can" change the class to witch without fear... there is only one more thing... I will lose all the skills that I didn't get in the original class, BEFORE changing class, am I right? So, the final skills of let's say, augur, will be lost forever right? To get all skills of my original class and the new class, witch, should I wait? Or can I get that skills in some other way?
I am really sorry to be so stubborn, and I really thank you for your help.
EDIT: I post this before reading the last message. Now I understand better. Thank you all ^^
