Sorry for such a dumb question, but I can't seem to find the answer even though I've been looking in the core rulebook and the rulebook that came with the beginner game.
I know that if your strain goes above your strain threshold, you become incapacitated. I know that you can voluntarily take on strain in some ways.
But what does strain actually do. Is there a difference between having a strain of 1 and a strain of 10 if they are both under your strain rating?
I asked somebody who was new to the game as well, and (they weren't sure) but they said that for each point of strain you take, you role a setback die when you do each skill check.... she thinks.....
Can somebody tell me what strain actually does? And if you can point me out to the page in the core rulebook where this is listed, I'd really appreciate it too.
