Can Mutants be all 3 classes, and is this table the only way they get untrained psychic sorcery, or is it in addition to if they roll 11+ for PS ?
At this point, my thinking is no Class-restrictions. And, yeah, in addition to random roll all characters get. Since you roll mutations before the untrained sorcery roll, you can skip the latter if you roll the sorcery mutation. By the same token, you might get size-change mutation and also roll for untrained sorcery.
Cool, but now I can't see any of my gaming group wanting to be a True Man - haha, until I bring on the persecution and slavery
You know, I was playing around with the Gamma World idea that True men might have a bonus to deciphering artifacts or something. But really, odds are that a mutation is useless, so I'm not sure I want to introduce that kind of thing,.
