Greetings o enlightened superbeings!
I've got a question. I'm making a character (a technological manipulator) who has an instinctive understanding of technology. It is INSTINCTIVE, not rational. He could fix a machine, or figure out how to get a computer to do something, but he doesn't really understand the theory of how he does it (he thinks he's appealing to the Machine Spirits that inhabit machines). So he would be unable to explain it to someone else, to theorize about it, and so forth. He can DO but not UNDERSTAND.
What kind of limit would you give for this? I'm thinking -1/2.
There is likely something about this in TUS, which I do not have...
