I searched the forums for Stress first, and couldn't find what I was looking for. Doesn't mean it isn't there, I just didn't find it if it is.

Okay, so I see that everyone starts with 2 stress boxes. There is a skill for each of them that can increase the number of boxes up to 4. Then there's Toughness, which increases the Physical stress boxes by twos. My question is, is there a way to increase the other stress boxes? I haven't found one in the book yet, but I'll keep looking.
