Question about joining groups. (Elex)

The situation is the following, I have done the necessary kveta have Berserkers and clerics. Each IG glavnyukov I gave the nod to joining their ranks. Have Berserkers: I have to agree to become a Berserker, and Reinhold is a dialogue: I want to become an acolyte of the clergy.
And here actually a question, If I become a Berserker and learn their magic in a dialogue with Rihardom disappear or still be available?
