Hello,
I have been going over the sorcerer rules and I am a little stuck on if you can get discipline mastery using sorcery.
1) Page 168 in the Radical Handbook and page 116 in Disciples of the Dark gods states that all psyhic powers can also be manifested as sorcery Arcana, and Discipline Powers count as Major Arcane with a threshold 2 higher. That is simple enough.
2) The Sorcery Talent (page 168 and 117 respectively as above) more or less says you get 3x your willpower bonus in Arcana, Major powers count as 2, and picking Arcana is not bound by the psyker's Discipline framework.
Does this main that sorcerer's can never have domain mastery? It seems to me no, but I wanted to see how everyone else does it. It just seems really difficult to manifest major Arcana and there is no hope of lowering thresholds. But then this is my first game and I have never ran a straight pskyer.
